Novel copolymer binder extends the life of lithium-ion batteries

Green Car Congress

One of the major causes for the drop in capacity over time in Li-ion batteries is the degradation of the widely used graphite anodes. interactions between the bis-imino-acenaphthenequinone groups and graphite, and also from the good adherence of the copolymer’s ligands to the copper current collector of the battery. 0c02742.
