Our new battery wont catch fire, even if you drill through it, Dai added.
People have tried different kinds of materials for the cathode, Dai said.
We accidentally discovered that a simple solution is to use graphite, which is basically carbon.
Smartphone owners know that it can take hours to charge a lithium-ion battery.
But the team reported unprecedented charging times of down to one minute with the aluminium prototype.
Aluminium batteries developed at other laboratories usually died after just 100 charge-discharge cycles.
But the Stanford battery was able to withstand more than 7,500 cycles without any loss of capacity.
Another feature of the aluminium battery is flexibility.
Aluminium is also a cheaper metal than lithium, Gong said.
I see this as a new battery in its early days, he added.
