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.
