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 this paper, the applications of porous negative electrodes for rechargeable lithium-ion batteries and properties of porous structure have been reviewed. Porous carbon with other anode materials and metal oxide’s reaction mechanisms also have been elaborated.
This results in a lithium metal negative electrode, used in both laboratory or industry scenarios, typically with a thickness of several tens to even hundreds of micrometers, which not only leads to the wastage of this costly metal resource but also significantly compromises the energy density of SSLMBs 10.
Therefore, it is reasonable to speculate that in the lithium-deficient scenario, the rapid consumption of active lithium metal in the negative electrode leads to the delithiation of Li 2 O to supplement lithium ions and maintain battery cycling 66.
In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
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.
