About Photovoltaic Energy StorageIntroduction. In the early 1990s, Moli and Sony used carbon materials with graphite structure to replace metal lithium anodes, and lithium and transition metal composite oxide such as LiCoO 2 served as the cathodes, leading to the commercialization of LIBs (Arora et al., 1998; Song et al., 1999; Lee and Lee, 2000; Pattipati et al., …
About Photovoltaic Energy StorageThe cathode active materials in LIBs are divided into lithium cobaltate (LiCoO 2, LCO), lithium iron phosphate (LiFePO 4, LFP), lithium manganite (LiMnO 2, LMO), and ternary nickel cobalt manganese (LiNi x Co y Mn 1-x-y O 2, NCM). [24, 25] The main economic driver for recycling the retired LIBs is the recovery of valuable metals from cathode …
