Lithium-metal anode-free batteries promise higher energy density and longevity, but their biggest problem is the dendrites that form inside the battery and ruin it. QuantumScape claims it solved this ...

A lithium-ion battery may have fewer parts than a combustion engine, but it's no less complex. It involves an intricate interplay of materials that influences an electric vehicle’s range, charging ...

Cathodes play a dominant role in defining cell energy density, and also make up a significant proportion of cell costs, due to the use of high-cost metals such as cobalt, nickel and lithium. Standard ...
