Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
In particular, three major design principles for electrode materials are summarized: (1) excellent host chemistry; (2) efficient ion and electron transport; and (3) long-term structural stability.
This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
For positive electrode materials, in the past decades a series of new cathode materials (such as LiNi 0.6 Co 0.2 Mn 0.2 O 2 and Li-/Mn-rich layered oxide) have been developed, which can provide a capacity of up to 200 mAh g −1 to replace the commercial LiCoO 2 (∼140 mAh g −1).
Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
