FAQ
Q.What is lithium cobalt oxide powder?
A.Lithium cobalt oxide powder (chemical formula LiCoO₂) is a black/greyish-black powder with a layered structure. It is the core positive electrode material for lithium-ion batteries, featuring high energy density and stable discharge performance. It is widely used in portable devices such as mobile phones. However, it has high costs (due to the scarcity of cobalt) and requires safety control. Efforts are being made to optimize it through modification or the development of alternative materials.
Q.The function of lithium cobalt oxide powder
A.Lithium cobalt oxide powder primarily functions as a cathode material in lithium-ion batteries. Its layered structure enables reversible lithium-ion insertion/extraction during charge-discharge, providing high energy density and stable voltage (≈3.7V). Critical for portable electronics (phones, laptops) due to its electrochemical performance, though limited by cobalt cost and safety concerns.
Q.How to select lithium cobalt oxide powder
When choosing lithium cobalt oxide powder, the following aspects should be considered: electrochemical performance (specific capacity 140-160mAh/g, cycle life, stable voltage at 3.7V); purity (impurities < 0.1%), particle size (D50 5-15μm and uniform distribution); safety (thermal stability); cost and cobalt content. Based on the application scenarios (such as portable devices), select products with high consistency as the priority.
