quality. LiCoO2 has a well-ordered layered crystal structure which favours fast and reversible lithium intercalation (Figure 5). However, is it very expensive owing to cobalt's rarity, toxic to humans and has relatively low theoretical capacity (~ 130 mA h g-1) . Figure 5: Layered, spinel and olivine structures for positive electrode materials for lithium ion batteries5. Besides the low capacity discharge, LiCoO2 is thermally…
