| Abstract: | With the miniaturization and lighting of the portable electronic products, and the rapid development of electric vehicles and grid energy storage devices, lithium ion batteries with higher energy density and higher performances are increasingly demanded. Cathode materials play a key role in lithium ion batteries and their improvements are crucial for enhancing energy density of lithium ion batteries. Nowadays, cathode materials of high energy density with lower production cost and high safety for lithium-ion batteries has been of great significance. This paper summarizes recent progress in cathode materials from the prospects of enhancing the specific capacity and the working voltage, and mainly focuses on design and preparation of meso-scale structured nickel-rich and lithium-rich layered oxide and spinel oxide cathode materials with tunable electrochemical performances. |
