How Li-containing alloys solving the present
issues?
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[34, 35], and they became commercially available somewhat
later[35]. Since then, researchers not only used the lithium alloys
as the anodes to reduce the activity of Li anode and stabilize
it[36], but also developing various kinds of other strategies, i.e,
constructing rational design of anode structure (3D hosts and 3D current
collectors)[25, 37], suppressing Li dendrite growth via modification
of electrolytes, separators and anode interfacial engineering[2,
38], etc.
