Because of these safety and cycle life problems with the use of elemental lithium, essentially all commercial rechargeable lithium batteries now use lithium–carbon alloys as negative electrode reactants today.
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.
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.
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.
