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 study was supported by the JST-Mirai Program (grant umber JP18077239). Graphite thus requires a binder to prevent it from falling apart with use. 0c02742.

U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

Ni NMA outperforms both NMC and NCA and only slightly trails NMCAM and a commercial cathode after 1000 deep cycles. The researchers have received grants from the US Department of Energy, which has sought to decrease dependency on imports for key battery materials. In pouch cells paired with graphite, high?Ni
