CC-BY 4.0 . The pursuit of new and better battery materials has given rise to numerous studies of the possibilities to use two-dimensional negative electrode materials, such as MXenes, in lithium-ion batteries.
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).
Ideally, the specific capacity of a negative electrode material should be higher than 372 mA h g –1, that is, the specific capacity of graphite, which is the most commonly used negative electrode material at present.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
Due to the smaller capacity of the pre-lithiated graphite (339 mAh g −1 -LiC 6), its full-cell shows much lower capacity than the case of Li 21 Si 5 (0.2–2 μm) (Fig. 6b), clearly indicating the advantage of the Li-rich Li-Si alloy as a promising lithium-containing negative electrode for next-generation high-energy LIBs.
It should be noted that the potential applicability of this anode material in commercial lithium-ion batteries requires a careful selection of the cathode material with sufficiently high voltage, e.g. by using 5 V cathodes LiNi 0.5 Mn 1.5 O 4 as positive electrode.
