Problem with graphene for ebike battery is it adds more weight.

"Twenty percent of a lithium-ion battery pack (in a vehicle) is to do with cooling them...It does not overheat and it nicely operates below zero so far in testing.... They don’t need circuits for cooling or heating, which currently accounts for about 80kg in a 100kWh pack... between 150 and 160Wh/kg and 7000W/kg. ” - May 2021

Developer Of Aluminum-Ion Battery Claims It Charges 60 Times Faster Than Lithium-Ion, Offering EV Range Breakthrough

The graphene aluminum-ion battery cells from the Brisbane-based Graphene Manufacturing Group (GMG) are claimed to charge up to 60 times faster than the best lithium-ion cells and hold more energy.

Cooling and heating circuits on Li-ion are largely unnecessary. That's why my latest Nissan Leaf series did away with them, increasing their range most of each year.

Their battery heating circuit on the previous Leaf didn't cut in until temperatures were far lower than we usually experience in Britain and in our climate and traffic conditions they had little chance to overheat.

And many of them have been sold and used in Norway which straddles the arctic circle.

Disruption or hype: Are sodium-ion batteries catching up and replacing lithium-ion ones in EV?

Disruption or hype: Are sodium-ion batteries catching up and replacing lithium-ion ones in EV?

In recent years, the popularity of sodium-ion batteries has suddenly risen. Chinese companies such as Contemporary Amperex Technology (CATL), Gotion Hi-Tech, EVE Energy and BYD are all engaging in researching sodium-ion batteries. CATL is even about to put them into mass production. Here are...
