Urgency of LiFePO 4 as cathode material for Li-ion batteries

. The energy crisis involving depletion of fossil fuel resource is not the sole driving force for developing renewable energy technologies. Another driving force is the ever increasing concerns on the air quality of our planet, associated with the continuous and dramatic increase of the concentration of greenhouse gas (mainly carbon dioxide) emissions. The internal combustion engine is a major source of distributed CO 2 emissions caused by combustion of gasoline derived largely from fossil fuel. Another major source of CO 2 is the combustion of fossil fuels to produce electricity. New technologies for generating electricity from sources that do not emit CO 2 , such as water, solar, wind, and nuclear, together with the advent of plug-in hybrid electric vehicles (PHEV) and even all-electric vehicles (EVs), offer the potential of alleviating our present problem. Therefore, the relevant technologies in LiFePO 4 as cathode material for Li-ion batteries suitable to the friendly environment are reviewed aim to provide the vital information about the growing field for energies to minimize the potential environmental risks.
