Providing the next breakthrough technology with Aluminium Graphite Dual ion Battery

Today’s portable electronic devices rely upon rechargeable batteries with low weight and
volume, and long life as essential components. With every new product launch mobile
devices becoming increasingly smaller, slimmer and lighter weight and at the same time
increasingly feature and function rich, placing more demands on the batteries and less
room to store the energy in the component.

If we compare advances in microprocessors to advances in the energy density of batteries,
the seriousness of the problem becomes immediately apparent. The performance of
microprocessors that power the worlds smart phones has been doubling every 18 months,
power demand doubling every 36 months, however battery performance lags dramatically,
doubling every 10 years.

Over the last decade lithium batteries have overtaken nickel cadmium and nickel metal
hydride rechargeable batteries, as the battery of choice for mobile electronics and today
lithium batteries have a 70% market share. Lithium-ion batteries are attractive due to
their lithium cells having a high energy density making them small, lightweight and with
a longer life span than traditional batteries.

One example is smartphones. Most people can’t live without their smartphones, but the
biggest overriding issue for most consumers remains the battery life. Even as developers
produce more efficient hardware, in the race to have the fastest performance, the best
camera and the display and features, any improvements in battery capacity are soon
used up. Although lithium-ion batteries have not yet reached their capacity limit, the
gap between energy power demand and capacity is unlikely to keep pace.

The main limitations of lithium-ion batteries are due to the materials used for the anode,
cathode and electrolyte. The major variation of LiETs,

AGDiBs are (1) the use of graphite cathode (2) aluminum counter electrode (3) conventional lithium salt and carbonate solvent as the electrolyte.

Independent research into aluminum batteries at Stanford University has confirmed that the AGDiB is an ultra-fast-charging battery that can fully charge a smart phone battery in around 60 seconds! This is nearly 100 times faster than the maximum charge rate for a lithium-ion battery. The battery can even be bent and folded safely, and the researchers drilled a hole through it while it was operating without causing a angerous short circuit.

Compared with conventional LIBs, this battery (AGDiB) shows an obvious advantage specific density (~1.3-2.0 times), and energy density (~1.6-2.8 times). This discovery is particularly important given rising battery demand and existing LIB technology, which is reaching its limit in specific energy (by weight) and energy density (by volume).

The AGDiB is a disruptive new rival to the lithium-ion battery, which is light weight, low-cost battery which performs better than lithium ion batteries that currently power smartphones and other portable devices.
