Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
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.
This review presents a new insight by summarizing the advances in structure and property optimizations of battery electrode materials for high-efficiency energy storage. In-depth understanding, efficient optimization strategies, and advanced techniques on electrode materials are also highlighted.
Recent trends and prospects of anode materials for Li-ion batteries The high capacity (3860 mA h g −1 or 2061 mA h cm −3) and lower potential of reduction of −3.04 V vs primary reference electrode (standard hydrogen electrode: SHE) make the anode metal Li as significant compared to other metals , .
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.
