Characteristics and development of vanadium phosphate lithium ion battery
In the early 1970s, the research work of lithium-ion batteries was promoted due to the energy crisis, and lithium primary batteries with Li or Li-Al alloy as negative electrode materials, including Li/MnO2, Li/I2, Li/SOCl2, Li/FeS2, etc., appeared one after another. In 1970, Japan’s panasonic company obtained a patent for Li/(CF)n batteries in the United States, and during the discharge process (CF)n was lithiated into C and LiF, and the reaction was not reversible, so the lithium primary battery at [...]
