Application characteristics:
, Nano-alumina is used as an electrode coating for lithium batteries, which can effectively insulate and insulate, and improve safety performance
Doping aluminum into lithium cobalt oxide can form a solid solution, stabilize the crystal lattice, and improve Rate performance and cycle performance.
3. Coating lithium cobalt oxide with nano-alumina can improve thermal stability, improve cycle performance and overcharge resistance, inhibit the generation and decomposition of oxygen, avoid direct contact with the electrolyte, and reduce The electrochemical specific capacity is lost, thereby increasing the electrochemical specific capacity.
, The doping of aluminum ions in nano-alumina can increase the voltage of the battery, thereby improving the safety of the battery.
Nano-alumina is used to modify spinel lithium manganate materials and produce The resulting battery has a reversible capacity of 1000 cycles per gram and a capacity retention rate greater than that of similar international products. It is the first material in China that can be used in high-power lithium-ion batteries.
