Cobalt-free batteries could power cars of the future
A new battery material could offer a more sustainable way to power electric cars. The lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel.
Next-generation batteries could go organic, cobalt-free for long-lasting power
In the switch to ‘greener’ energy sources, the demand for rechargeable lithium-ion batteries is surging. However, their cathodes typically contain cobalt — a metal whose extraction has high environmental and societal costs. Now, researchers in report evaluating an earth-abundant, carbon-based cathode material that could replace cobalt and other scarce and toxic metals without sacrificing lithium-ion battery performance.
