Since lithium metal functions as a negative electrode in rechargeable lithium-metal batteries, lithiation of the positive electrode is not necessary.

As discussed below, this leads to significant problems. Negative electrodes currently employed on the negative side of lithium cells involving a solid solution of lithium in one of the forms of carbon. Lithium cells that operate at temperatures above the melting point of lithium must necessarily use alloys instead of elemental lithium.
There has been a large amount of work on the understanding and development of graphites and related carbon-containing materials for use as negative electrode materials in lithium batteries since that time. Lithium–carbon materials are, in principle, no different from other lithium-containing metallic alloys.
This type of cell typically uses either Li–Si or Li–Al alloys in the negative electrode. The first use of lithium alloys as negative electrodes in commercial batteries to operate at ambient temperatures was the employment of Wood’s metal alloys in lithium-conducting button type cells by Matsushita in Japan.
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.
The first use of lithium alloys as negative electrodes in commercial batteries to operate at ambient temperatures was the employment of Wood’s metal alloys in lithium-conducting button type cells by Matsushita in Japan. Development work on the use of these alloys started in 1983 [ 29 ], and they became commercially available somewhat later.
