Novel copolymer binder extends the life of lithium-ion batteries

Green Car Congress

One of the major challenges for graphite anodes is the exfoliation of the graphite framework on deep cycling at a fast current rate. This comes in part from the ?-? 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.
