Li-rich Mn-based layered oxide cathodes (LLOs), delivering high specific capacity of >300 mAh g −1 and maximum energy density of >1000 Wh kg −1, are deemed to be one of the most promising cathode candidates for next-generation lithium-ion batteries over 350 Wh kg −1 at the full cell level.
Lithium layered cathode materials, such as LCO, LMO, LFP, NCA, and NMC, find application in Li-ion batteries. Among these, LCO, LMO, and LFP are the most widely employed cathode materials, along with various other lithium-layered metal oxides (Heidari and Mahdavi, 2019, Zhang et al., 2014).
To achieve this goal, understanding the principles of the materials and recognizing the problems confronting the state-of-the-art cathode materials are essential prerequisites. This Review presents various high-energy cathode materials which can be used to build next-generation lithium-ion batteries.
Lithium nickel cobalt aluminium oxide is a class of cathode active material used in LIBs. NCA batteries are used in several high cost, high performance EVs. Next-generation NCA-type cathodes include lithium nickel cobalt manganese aluminium oxides (NMCA). Lithium nickel manganese cobalt oxide is a class of cathode active material used in LIBs.
In the last two decades, lithium-ion batteries have been the most robust technology, supplying high energy and power density. Improving cathode materials is one of the ways to satisfy the need for even better batteries.
In order to improve the performance, Liu et al. developed heterostructured spinel/Li-rich layered oxide (Li 1.15 Ni 0.20 Mn 0.87 O 2) nanofibers as superior cathode materials for recharhable Li-ion batteries .
