An open electrolytic cell has been designed and constructed
for use in a dry environment. This was used to investigate the
passivation processes concerned with both the lithium and the
carbon (SO2) electrodes.
A.c. impedance techniques have been used in both two and
three terminal cell systems in order to study the kinetics of the
electrode processes. Effects of temperature, state-of-charge and
reverse cell operation have been studied.
Computer simulations were made of the growth of crystals on a
flat (Li) surface and the resulting growth transients connecting
current and time were derived. This model was extended to simulate
the porous carbon (SO2) electrode and the utilisation of the carbon
as a function of the depth of reaction penetration into the
electrode is devised for both potentiostatic and galvanostatic
discharging.
