Conventional batteries have anodes and cathodes, but a new design from the University of Chicago and the University of California San Diego lacks an anode. While this has been done before, according ...

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 ...

Lithium-ion batteries are used not only for small consumer electronics like cell phones and laptops, but also electric bicycles, electric vehicles, and long-term power storage. Though rare, ...

A study team created a prototype calcium (Ca) metal rechargeable battery that can withstand 500 cycles of repeated charge-discharge—the practical limit. Schematic of a prototype Ca metal battery. The ...

Stanford University researchers found that the best way to extend the life of a lithium-metal EV battery is to drain it and let it rest for a few hours. The study, “Resting restores performance of ...

Could an electric vehicle travel from Seoul to Busan and back on a single charge? Could drivers stop worrying about battery performance even in winter? A Korean research team has taken a major step ...

Solid-state batteries promise to elevate Li-Ion batteries to new highs, thanks to the advantages of using solid electrolytes. Scientists at the University of Texas at Austin have discovered that ...

Battery start-up QuantumScape believes ditching the anode can unlock big improvements in EVs, but challenges persist. A lithium-ion battery may have fewer parts than a combustion engine, but it's no ...

As more and more Americans embrace electric vehicles, automakers and the federal government are racing to secure the materials needed to build EV batteries, including by pouring billions of dollars ...
