Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
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.
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.

The cathode materials of lithium batteries have a strong oxidative power in the charged state as expected from their electrode potential. Then, charged cathode materials may be able to cause the oxidation of solvent or self-decomposition with the oxygen evolution. Finally, these properties highly relate to the battery safety.
They did not succeed in making the metallic lithium battery safe, especially at the end of cycle life or on quick charge as evidenced by the total recall of rechargeable batteries with metallic lithium . The first lithium-ion batteries reported in literature consisted of LiCoO 2 and petroleum coke .
