Tin-sulfur-lithium accumulator
The tin-sulfur-lithium battery is an experimental secondary cell that was presented in March 2010 by the Italian researchers Bruno Scrosati and Jusef Hassoun at the University of Rome. The negative electrode of the tin - sulfur - lithium accumulator consists of a carbon - lithium sulfide composite, the positive electrode consists of a tin-carbon compound.
properties
The energy density of the tin-sulfur-lithium battery stated by the researchers, at approx. 1100 Wh / kg, exceeds that of all conventional batteries many times over. Since the accumulator does not contain any metallic lithium , a higher level of operational reliability can be guaranteed than with the lithium-sulfur accumulator .
According to the researchers , the road to a usable lithium-sulfur battery is still long . In particular, the number of possible charge / discharge cycles has to be increased.
