Another day, another post from batt-crazy me.
IBM proposes sustainable successor to lithium-ion battery
The juicy bits:
Importantly, they have also proved that the battery outperforms lithium-ion versions, so it has the potential to improve electric vehicles and energy storage.
When optimised for performance, the battery has a higher power density than lithium-ion, meaning potentially smaller batteries that could be transformative for technology like electric aircraft.
In addition, it takes only five minutes to reach an 80 per cent charge, a length of time similar to filling up a tank of petrol at a service station. It is also low-cost, thanks to the materials sourcing method, and has low flammability, so it is safer to use.
