Prieto 3D Lithium Ion Battery: The Ideal Battery For The Here and Now?
While batteries offering ultra-fast charging and higher capacity still await millions in crowdfunding capital, is the Prieto 3D lithium ion battery the ideal Airsoft battery for the here and now?
By Ringo Bones
Ever noticed why those ultrafast charging and very high
capacity rechargeable batteries exhibited during the 2015 Consumer Electronic
Show in Las Vegas are still not available to the consumer market in 2017? Well,
those batteries require manufacturing plants that are radically different from
existing ones that are currently manufacturing your run-of-the-mill lithium ion
batteries currently used in cars, laptops and smartphones. They are probably still
waiting millions in crowdfunding dollars to be able to make those batteries
available to consumers at a reasonable cost while making themselves a tidy
profit. But is there a way to increase the power capacity of lithium ion
batteries in an evolutionary – rater than a revolutionary manner – i.e. using
existing manufacturing facilities and off-the-shelf materials thus making it
ideal for current Airsoft use?
Dr. Amy Prieto, CEO of Prieto Battery in which she founded
back in 2009, has a way to make existing lithium ion batteries better while
using current battery manufacturing plants. All it takes is a clever use of
existing materials and on the way they are fabricated. Prieto is poised to
commercialize a battery that will deliver transformational performance – as in
higher power density, longer life cycle, safe and much greater energy density
than existing lithium ion batteries. It is called the Prieto 3D Lithium Ion
Battery.
The Prieto 3D Lithium Ion Battery uses a copper foam
substrate electrode which provides higher electrode surface area and a shorter
ion diffusion path that results in a five-fold increase in power density. It
has a copper antimonide for a three-fold increase in volumetric energy capacity
and the proprietary anode deposition eliminates the need of lithium dendrites.
Its solid polymer electrolyte results in a safer, nonflammable battery and also
increases its lifecycle. And while using standard industry available cathode
materials, it is easier to customize the cell voltage and capacity and with its
water-based process during electroplating results in a lower cost when it comes
to scaling up in its manufacture.

Can Augmented Reality Improve Your Airsoft Gaming Experience?
Given the recent success of Pokémon
GO, can augmented reality improve or at least make a more interesting airsoft
gaming experience?
By: Ringo Bones
With the recent success of Pokémon
GO, augmented reality gaming seems to be the in thing at the moment if you own
an advanced enough smart-phone. And given the relative ubiquity of advanced
smart-phones, can augmented reality elements be introduced to airsoft gaming to
make it more interesting? But first, an introduction to what is this augmented
reality business….
Augmented reality (AR) is a live, direct or indirect, view
of a physical, real-world environment whose elements are augmented by
computer-generated sensory input such as sound, video, graphics or GPS data. It
is related to a more general concept called mediated reality, in which a view
of reality is modified (possibly even diminished rather than being augmented),
by a computer. As a result, the technology functions by enhancing one’s current
perception of reality. By contrast, virtual reality replaces the real world
with a simulated one. Augmentation is conventionally in real-time and in
semantic context with environmental elements, such as sports scores on TV
during a match. With the help of advanced AR technology (e.g. adding computer
vision and object recognition) the information about the surrounding real world
of the user becomes interactive and can be digitally manipulated. Artificial
information about the environment and its objects can be overlaid on the real
world.
With the proper creative application of augmented reality,
airsoft gamers would soon be closer to playing in a gaming environment closely
resembling to that of James Cameron’s Avatar or those exotic extraterrestrial
locales of the Halo computer gaming series and even a passable World War II,
Vietnam War, and the recent Gulf conflict of the Call of Duty gaming series. It
seems that augmented reality applications for airsoft will only be limited by
the gamers’ imagination.

Stanford University’s Advanced Aluminum Battery: The Future of Airsoft Rechargeable Batteries?
With several competing “futuristic” ultrafast-charging
rechargeable batteries, is Stanford University’s Advanced Aluminum Battery
poised to be the future of rechargeable batteries?
By: Ringo Bones
Technology experts recently quipped that if the advances
made in rechargeable battery technology during the past 60 years mirrored that
of semiconductors, we would have today rechargeable batteries that could power
a mobile phone for a million years on a single charge. Sadly, such technology
is still beyond the reach of the current major consumer electronic
manufacturers, but recently, prototypes of ultrafast-charging rechargeable
batteries that with a minutes worth of charging could either power a mobile
phone for a day or drive an electric car for 300 miles are now a prototypical
reality.
Lithium ion batteries have been a boon for the modern world
in that they’ve replaced the heavier single-use alkaline type batteries in everything
from wristwatches to the power supplies of flight control systems in late-model
jumbo jets. Unfortunately, these rechargeable cells are already struggling to
keep up with our ever increasing energy needs. But a new type of aluminum-ion
battery recently developed by graduate students and their professor at Stanford
University is not only less prone to bursting into flames than current
lithium-ion types - something often demonstrated via You Tube videos posted in online Airsoft gaming sites and forums - but can also be built at a fraction of the price and
recharges completely in just over a minute. Best of all, “our new battery won’t
catch fire, even if you drill through it” says Stanford University chemistry
professor Hongjie Dai.
According to its developers, the Stanford University’s
Advanced Aluminum Battery uses a graphite cathode, an aluminum anode and an
ionic liquid electrolyte inside a polymer-coated pouch. “The electrolyte is
basically a salt that is liquid at room temperature, so it’s very safe” said
Stanford University graduate student Ming Gong, co-author of the study recently
published in the science journal Nature.
Unlike earlier rechargeable aluminum-ion battery prototypes
which generally fails after only about 100 recharge cycles, Stanford’s
prototype Advanced Aluminum Battery are composed of aluminum-ion cells that can
cycle more than 7,500 times without any capacity loss – that’s 7.5 times longer
than your average lithium-ion rechargeable battery in current production.
Sadly, Stanford University’s aluminum-ion cell isn’t perfect, yet, as it can
produce only about 2 volts per cell – far less than the 3.6 volts per cell that
current lithium-ion cells can muster. Plus aluminum-ion cells, at the moment,
can only carry 40-watts of electricity per kilogram compared to lithium-ion’s
100 to 206 watts per kilogram power density.
“Improving the cathode material could eventually increase
the voltage output and energy density” says Dai. “Otherwise, our battery has
everything else you’d dream that a battery should have: inexpensive electrodes,
good safety, high-speed charging, flexibility and long cycle life. I see this
as a new battery in its early days, It’s quite interesting.”
Unlike other competing prototypes, Stanford University’s
Advanced Aluminum Battery that has the ability to be charged for 1 minute and
yet could store enough charge to power a mobile phone for 24 hours was entirely
made possible by a group of graduate students and their professor without a
single cent of corporate backing whatsoever. Despite of this feat, Tesla
electric car company founder Elon Musk is currently skeptical of the Stanford
University’s Advanced Aluminum Battery on whether it will ever be as good – or
become even better than – as those ultrafast-charging lithium ion types in
current development. Hmm, if only Tesla Motors CEO Elon Musk would put his
money where his mouth is…Or maybe Airsoft electric gun manufacturers should
check out Stanford University’s Advanced Aluminum Battery for potential Airsoft
gaming applications.

StoreDot’s Fast Charging FlashBatteries: The Future Of Rechargeable Airsoft Batteries?
With the ability to recharge in 60 seconds to power a mobile
phone or allow an electric vehicle to travel 300 miles with a 5 minute charge
is StorDot’s FlashBattery represent the future of rechargeable battery
technology?
By: Ringo Bones
During the 2015 Consumer Electronics Show – CES – in Las
Vegas, Nevada, an Israeli firm called StoreDot demonstrated a newfangled
battery technology that can power a mobile phone with just a 60-second charge
and a bigger version that could drive an electric vehicle for 300 miles (480
kilometers) on a 5 minute charge. With such capability, StoreDot’s FlashBattery
technology could represent the future of rechargeable battery technology where
battery recharging of electric cars and other electric vehicles could be as
fast as the time it takes to fill up with gasoline in your local gasoline
filling station. Just imagine what it could do to the weekend Airsoft gamer who forgot during the whole working week to recharge his or her own batteries for AEG Airsoft gun use.
Lithium ion batteries contain inorganic compounds in the
battery’s cathode, typically comprising metal oxides or polyanions which are
continuously recharged by the insertion of lithium ions. This process limits
ionic conductivity, thereby reducing the power density and shortening the
battery’s life expectancy. Moreover, the electrolyte used in lithium ion
batteries is highly volatile and flammable, posing a severe risk to consumers,
critical especially in electric cars.
This optimized charging ability is achieved through an
innovative electrode structure containing proprietary organic polymers with
legacy lithium metal oxide components on the cathode end that trigger
reduction-oxidation chemical reactions. This solution causes ions to flow from
a modified anode to a modified cathode at a speed that could not be attained
through existing lithium ion battery technologies. Together with a proprietary
separator and electrolyte, this new architecture delivers a high current and
low internal resistance with enhanced energy density and a prolonged battery
life.
While some battery manufacturers were able to improve only one of the
following properties – either an increase in capacity, fast charging or
extended battery life – StoreDot’s novel technology has optimized all three
simultaneously, in addition to enhancing its safety. StoreDot’s organic compounds and newfangled proprietary
battery architecture provide 4 times more charge / discharge cycles compared to
any existing rechargeable battery, increasing the number of cycles from 500 to
2,000. Using compounds that are less likely to metalize during these cycles,
StoreDot’s FlashBattery eliminates the risk of an internal electrical short
almost entirely, which significantly prolongs battery life expectancy.
Specially designed for high current charging, StoreDot’s
FlashBattery contains, in addition to lithium, non-flammable organic compounds
encased in multi-layer safety-protection structure that prevents over voltage
and heating and is therefore considerably safer than traditional lithium ion
batteries. Containing their proprietary electrolyte which is an
ecologically-friendly material, the FlashBattery meshes polymers and metal
oxide together, resulting in an increased electrode stability and SEI
performance at high temperatures.

Anode-Less Rechargeable Batteries: The Future of Airsoft Batteries?
Even though it is an integral part of a rechargeable
batteries construction for proper operation, could eliminating the anode
improve current rechargeable batteries performance for Airsoft use by leaps and bounds?
By: Ringo Bones
Though not quite anode-less yet but a rechargeable battery
manufacturing company called Solid Energy Systems is currently developing a
nearly anode-less lithium ion rechargeable battery and has recently exhibited a
working prototype during the 2015 Mobile World Congress in Barcelona, Spain. Given
the already widespread acceptance of the lithium ion rechargeable battery in
mobile phone and hybrid / electric vehicle applications, Solid Energy System’s
concept takes the strengths of the current technology much further by reducing
the space taken up by the anode since it takes up most of the space in current
lithium ion rechargeable battery configuration. This means more compact - as in smaller - Airsoft batteries with similar or more powerful than - the ones currently available.
Solid Energy System’s nearly anode-less rechargeable battery
concept could last twice as long as current lithium ion rechargeable batteries,
while offering a 1,200 watt-hour per liter energy density. Designed with an
ultra-thin metal anode, this configuration improves the cell-level energy
density by 50-percent over current designs using graphite anodes and 30-percent
improvement over silicon-composite anodes. Once marketed and used on current
mobile devices, it could make them operate twice as long between recharging
times.
According to Solid Energy Systems, the “secret” in boosting
energy storage lies in swapping the conventional electrode material – graphite
– for a thin sheet of lithium metal foil, which can store more lithium ions.
Other battery manufacturers have been trying to use lithium-metal electrodes in
rechargeable lithium ion batteries for decades with only a limited success.
Solid Energy seems to have solved a couple of key problems which have caused
such batteries to either stop working after a few charges or burst into flames.
Current carbon anode cell energy density is at 600 watt-hour per liter while
silicon anode cells offer energy densities of around 800 watt-hour per liter,
while Solid Energy Systems’ near anode-less cell offer energy densities of
around 1,200 watt-hour per liter.
Solid Energy Systems’ solution to make nearly anode-less
rechargeable batteries to be as reliable as current lithium ion rechargeable
cells without dying only a few recharge cycles or suddenly bursting to flames
is via the use of both solid electrolyte and a liquid one. The solid electrolyte
is applied to the lithium-metal foil, the ions don’t have to travel through
this thin material, so it doesn’t matter that they are moving relatively
slowly.
Solid Energy Systems’ prototype nearly anode-less battery
can be recharged 300 times while retaining 80 percent of its original storage
capacity – closer to what you would need in portable electronics. It also works
at room temperatures whereas competing lithium-metal battery prototypes operate
at temperatures too hot to be practical. As of late, most other companies
investing in Solid Energy Systems’ newfangled batteries to become an
economically viable commercial product are electric car / hybrid car companies
with plans to use the newfangled rechargeable battery design in their electric
cars.

The Tamir Rice Airsoft Gun Case: A Blow To Airsoft Gaming?
Will the apparent accidental shooting death of Tamir Rice by
Cleveland police place stricter laws against Airsoft replica gun ownership?
By: Ringo Bones
The shooting of Tamir Rice, a 12 year old African American
boy occurred on November 22, 2014 in Cleveland, Ohio. Two police officers, 26
year old Timothy Loehmann and 46 year old Frank Garmback responded after
receiving a police dispatch call “of a male sitting on a swing and pointing a
gun at people” in a city park. A caller reported that a male was pointing “a pistol”
at random people in Cudell Recreational Center. The caller stated twice that
the gun was: “probably fake.” Toward the end of the 2 minute 17 second 911
call, the caller stated “he is probably juvenile.” The officers reported that
upon arrival, Rice reached towards a gun in his waistband. Loehmann fired two
shots within two seconds on arriving in the scene, hitting Rice once on the
torso.
Rice’s gun was later found to be an Airsoft replica, though
lacking the orange safety feature signifying that the gun is not real. Rice
died on the day after the shooting. His death has been ruled a homicide by the
Cuyahoga County medical examiner. The tragic incident has yet to raise the
question of the safety of Airsoft gun ownership in the United States.
In the United States under federal law, Airsoft guns are not
classified as firearms and are legal for all ages. Although persons under 18
years of age are not permitted to purchase Airsoft guns over the counter in
stores, however a person of any age may use one. But there are selected local
requirements. Some cities in the state of Illinois consider shipping or
distributing Airsoft guns illegal. Enforcement of local laws with regards to
Airsoft replica gun bans is often intermittent. There are many fields and
stores in operation and sporting goods stores regularly carry Airsoft replica
guns. However a man was arrested back in 2013 for firing a replica gun /
Airsoft gun in his own backyard.
