Development of the next-generation rechargeable battery is going to directly impact the performance and capabilities of electric vehicles. Current lithium-ion [Li-ion] battery technology has a maximum density of 250Wh/kg, […]

The element that powers them is considerably expensive and it is expected that the price will rise with the increasing number of electric vehicles on the market. Hence, scientists from around the world have been […]
