Tin and tin-based intermetallics as new anode materials for lithium-ion cells

摘要

The galvanostatic cycling behaviour of Sn/SnSb composite electrodes has been studied in 1 mol l~-1 LiCIO_4/propylene carbonate (PC), l mol l~-1 LiPF_6/ethylene carbonate (EC)/diethyl carbonate (DEC) (1:1), and l mol l~-1 LiCIO_4PC saturated with trans-decalin (t-Dec). Capacities between 500 and 600 mA h g~-1 (With respect to the mass of active material) were obtained.
