Lithium-ion batteries that last longer in extreme cold

A lithium-ion battery made with a bumpy carbon-based anode material maintained its rechargeable storage capacity in extreme cold

13-Jun-2022 - When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion batteries’ anodes get sluggish, holding less charge and draining energy quickly. To improve electrical performance in the extreme ...
