Then the team tested the material’s electrical performance as the anode, with lithium metal as the cathode, inside a coin-shaped battery. (a) In comparison, lithium-ion batteries made with other carbon-based anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. C and maintained 85.9%
