The overall reaction OAR becomes highly reversible, and is suitable for the reversible Li" storage of electric energy ( lithium ion batteries ). Accordingly, acceptor-electrodes ( p-type ) are initially oxidized, and the charge is compensated by the insertion of anions. The overall reaction is written as ...

Graphitic carbon is now used as the anode material in lithium-ion batteries produced by Moli Energy (1990) Ltd., Matsushita, Sanyo and A+T battery. It is important to understand how the structures and properties of graphitic carbons affect the intercalation of lithium within them. 

The reciprocal value, / = l/V/Ah of the coulometric efficiency is called the charging factor. The coulometric efficiency for electrochemical energy conversion is about 70-90 percent for nickel/cadmium and nearly 100 percent for lithium-ion accumulators [14]. 

Secondary lithium-metal batteries which have a lithium-metal anode are attractive because their energy density is theoretically higher than that of lithium-ion batteries. Lithium-molybdenum disulfide batteries were the world s first secondary cylindrical lithium—metal batteries. However, the batteries were recalled in 1989 because of an overheating defect. Lithium-manganese dioxide batteries are the only secondary cylindrical lithium—metal batteries which are manufactured at present. Lithium-vanadium oxide batteries are being researched and developed. Furthermore, electrolytes, electrolyte additives and lithium surface treatments are being studied to improve safety and recharge-ability.

Of these requirements (1) - (4) relating to the energy density and requirements (8) and (10) associated with safety are most important behavior criteria for insertion materials for lithium-ion batteries, even in basic research. 

Carbons exhibiting hysteresis show poor cycling performance, and can be discharged only in a broad potential region of about 1-2 V (Fig. 13) [41, 51, 52, 218-220, 234-236, 244, 277, 278, 287], As a result, the energy efficiency of a lithium-ion cell is reduced. 

In conclusion, it seems that solvents appropriate for lithium-ion batteries employing a graphite anode must have high solvation energy, high E°, and high /0 for reduction in order to slow the cointercalation of the solvated ion, and to enhance the formation of the SEI at the most positive potential (far from the Li/Li+ potential).
