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).
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.
Lithium manganese spinel oxide and the olivine LiFePO 4 , are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.
