Doping of LiCoO2

Doping of LiCoO2

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 […]

About the preparation method of LiCoO2

About the preparation method of LiCoO2

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

Structure and electrochemical performance of LiCoO2 electrode material

Structure and electrochemical performance of LiCoO2 electrode material

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
