Portable devices in our daily life become thinner, lighter, faster and more capable. But through it all, battery life has mostly stayed the same.
Virtually every electronic device today relies on lithium-ion batteries, which provide power by transferring ions between the anode and cathode of a battery cell. The amount of lithium ions inside the battery directly affects how long your device can last on a charge.
The problem lies in the graphite that stores lithium ions in the anode of a battery. Graphite has a theoretical limit to how much lithium it can hold, and today's batteries have pretty much reached it.
So how can we improve the capacity of today's batteries?
The answer is Graphene, a Nobel prize-winning material made from atom-thick layers of graphite.
Graphene has a high surface area to mass ratio and it means more space in which to store energy, without increasing the total mass of battery.
Graphene is also the most conductive material that can offer 10 times faster charging speed.
This means, charging your phone in minutes instead of hours! which will last 4 days straight.
