... At this time, the more promising materials for the positive (cathode) electrode of lithium ion batteries (LIB) in terms of electrochemical properties and safety has been the lithium iron phosphate, LiFePO4 (LPF), powders.
Since lithium is more weakly bonded in the negative than in the positive electrode, lithium ions flow from the negative to the positive electrode, via the electrolyte (most commonly LiPF6 in an organic, carbonate-based solvent20).
The positive electrode is activated carbon and the negative electrode is Li [Li 1/3 Ti 5/3 ]O 4. The idea has merit although the advantage of lithium-ion battery concept is limited because the concentration of lithium salt in electrolyte varies during charge and discharge.
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.
