Since the rapid development of Li (Na) ion batteries, increasing the electrochemical performance of the cathode material is the most urgent task. The basic characteristics, advantages, and disadvantages of typical cathode materials are summarized in Table 1 .
A multi-institutional research team led by Georgia Tech’s Hailong Chen has developed a new, low-cost cathode that could radically improve lithium-ion batteries (LIBs) — potentially transforming the electric vehicle (EV) market and large-scale energy storage systems.
[ 94] In the research of lithium-ion battery cathode materials, another cathode material that has received wide attention from both academia and industry is the spinel LiMn 2 O 4 cathode material proposed by Thackeray et al. in 1983. LiMn 2 O 4 has three-dimensional Li transport characteristics.
Li-based Layered metal oxides with the formula LiMO 2 (M=Co, Mn, Ni) are the most widely commercialized cathode materials for LIBs. LiCoO 2 (LCO), the parent compound of this group, introduced by Goodenough was commercialized by SONY and is still employed as the most active cathode material for LIBs.
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 .
Recent advantages and future prospects of cathode materials towards the exploration of future-generation LIBs have also been highlighted in this review, aiming to remarkably reduce the cost and enhance the efficiency of future LIBs, which may revolutionize the transportation way and various aspects of our lives. 1.
