Lithium is a highly interesting metal, in part due to the increasing interest in lithium-ion batteries. Several recent studies have used different methods to estimate whether the lithium production can meet an increasing demand, especially from the transport sector, where lithium-ion batteries are the most likely technology for electric cars. The reserve and resource estimates of lithium vary greatly between different studies and the question whether the annual production rates of lithium can meet a growing demand is seldom adequately explained. This study presents a review and compilation of recent estimates of quantities of lithium available for exploitation and discusses the uncertainty and differences between these estimates. Also, mathematical curve fitting models are used to estimate possible future annual production rates. This estimation of possible production rates are compared to a potential increased demand of lithium if the International Energy Agency’s Blue Map Scenarios are fulfilled regarding electrification of the car fleet. We find that the availability of lithium could in fact be a problem for fulfilling this scenario if lithium-ion batteries are to be used. This indicates that other battery technologies might have to be implemented for enabling an electrification of road transports. / Stand

Microstructure evolution at different stage of charge-discharge process of the SnO2 thin film electrode of the secondary lithium battery was studied in this work. In particular, the identity and amount of various phases were monitored as the lithium were inserted or exacted from the electrode. The SnO2 thin film ,though a negative-electrode material ,served as the positive electrode in the charge-discharge process .The counter electrode was a pure lithium foil. As obtained from the X-ray diffraction examination, £]-Sn phase increased gradually as the discharging process proceeded, reacting a maximum at the ending point of discharging(0.05V). The£]-Sn phase then decreased gradually as the charging process proceed and finally disappeared at the end of charging(2.5V). TEM observation indicates that SnO2 was present at the initial stage of discharging (up to ~0.91V),and at replaced at the end of discharging by£]-Sn which showed some agglomeration. Cracks on the thin film were observed by SEM offer discharging. They were formed due to the expansive caused by the formation of low-density phases.
