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 ...

In 2020, Tesla announced a breakthrough battery that would be much cheaper to produce while offering higher energy density thanks to new technologies like dry cathode coating and silicone anode.

Solid-state batteries for electric vehicles, offering greater energy density and range than contemporary lithium-ion batteries, remain out of reach, not least due to challenges coming from the ...

Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries. A collaboration ...

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 ...
