Development of long life lithium ion battery for power storage
1. IntroductionIn previous papers [1], [2], [3], the authors reported studies performed for the development of a 1 kWh class lithium ion battery for power storage, using LiCoO 2 and natural graphite as cathode and anode active materials, respectively, with 1 M LiPF 6 dissolved in ethylene carbonate/diethyl carbonate (EC/DEC) as an
