リチウムイオン電池の電極開発

摘要

正極材料と負極材料の容量を改善するための多くの研究が行われている．電池を実際に作製する場合，正極と負極の容量バランスが重要となる．負極括物質の容量がいくら大きくなっても電池のエネルギー密度は改善されない．%The development of electrodes for rechargeable lithium ion batteries was described in this report. Especially, a recent prog­ress on cathode and anode materials was summarized briefly. Rechargeable lithium ion batteries for electric vehicles were discussed based on material development for higher energy density and power density of batteries.
