Abstract
The theoretical capacity of SnO is much
larger than graphite when used as the
negative electrode of lithium-ion secondary
battery. The practical and efficient capacity
depends on the purity and microstructure
of electrode material powders.
Conventional preparation methods mostly
employ precipitation approach, which
produces amorphous SnO as well as
impurity SnO2. We proposed in this study
to produce SnO powders of high crystalline
and high purity based on hydrothermal
process. We also used SnO and
SnO/graphite composite materials as
negative electrode active materials. We
ensure the redox potential by differential
specific capacity management while taking
SnO and SnO/graphite as the negative
electrodes. The voltage of discharge of SnO/graphite composite materials is lower
than that of graphite, it also means the
working voltage is increased.
