In particular, the recent trends on material researches for advanced lithium-ion batteries, such as layered lithium manganese oxides, lithium transition metal phosphates, and lithium nickel manganese oxides with or without cobalt, are described.
The phosphate positive-electrode materials are less susceptible to thermal runaway and demonstrate greater safety characteristics than the LiCoO 2 -based systems. 7. New applications of lithium insertion materials As described in Section 6, current lithium-ion batteries consisting of LiCoO 2 and graphite have excellence in their performance.
It is an ideal insertion material for long-life lithium-ion batteries, with about 175 mAh g −1 of rechargeable capacity and extremely flat operating voltage of 1.55 V versus lithium. LiFePO 4 in Fig. 3 (d) is thermally quite stable even when all of lithium ions are extracted from it .
Electrode structure is an important factor determining the electrochemical performance of lithium-ion batteries. It comprises physical structure, particle size and shape, electrode material and pore distribution.
Negative electrodes based on lithium metal (Li) as active material allow a significant increase in the specific energy (Wh kg −1) of rechargeable batteries due to the physicochemical properties of Li such as the low standard reduction potential (–3.04 V versus standard hydrogen electrode) and light weight.
