Cathode material for battery
Due to the lack of cobalt resources and the high price, the application and development of lithium cobalt oxide, a cathode material for lithium-ion batteries, are limited due to high cost and other factors. In addition, studies have shown that pure LiCoO2 , when the amount of lithium ion deintercalation exceeds 50%, its electrochemical performance …
The synthesis methods of lithium cobalt oxide mainly include high temperature solid phase method and low temperature liquid phase method. Traditional high-temperature solid-phase reactions use lithium and cobalt carbonates, nitrates, acetates, oxides or hydroxides as lithium and cobalt sources. After mixing and pressing the tablets, they are heated to 600 ~ 900 ℃ in the …
The difference in the synthesis method creates LiCoO2. The different phases, although all embedded compounds, can be used as cathode materials for lithium-ion batteries, but the difference in crystal structure leads to differences in its electrochemical performance. The layered LiCoO2 (HT-LiCoO2) synthesized at high temperature has higher specific capacity, better cycle performance and safety, and …
