Carbon nanomembrane prevents dendrite formation in Li-metal batteries, doubles lifetime

Green Car Congress

The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future—in electric vehicles, for example. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. Here, the use of an ultrathin (?1.2

Study links carbon fiber microstructure to Li insertion mechanism in structural batteries

Green Car Congress

Carbon fibers have already beeen demonstrated as high-capacity Li-ion battery anodes, opening the way for their use as structural electrodes—i.e., This is why the IM CFs with a lithiation mechanism reminiscent of disordered carbons outperform the HM CF with its larger crystallites highly oriented along the fibre direction.
