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.
Since the cracking of carbon materials when used as negative electrodes in lithium batteries is very small, several allotropes of carbon can be used, including amorphous carbon, hard carbon, graphite, carbon nanofibers, multi-walled carbon nanotubes (MWNT), and graphene .
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.
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.
This type of cell typically uses either Li–Si or Li–Al alloys in the negative electrode.
