1. Lithium microbattery: principle and specific features
1.1 The benefits of lithium electrochemical systems
Among the many R&D projects currently being carried out on microbatteries, those involving systems with a lithium metal negative electrode are particularly promising.
There are three main reasons for this:
the potential of the Li + /Li couple is the lowest of all redox couples ( E 0 = – 3 V/ENH); lithium is in fact the most reductive element. It can be combined with any other material involving a redox couple and capable of inserting lithium, which then forms the positive electrode. The generator's potential difference can be as high as 3 to 5 V, depending on the material...
