Nano Aluminum Oxide for Lithium Battery Applications
- Utilizing Nano Alumina as an electrode coating in lithium batteries effectively provides insulation, enhancing safety performance.
- Introducing nano-alumina doped with aluminum into lithium cobalt oxide forms a solid solution, stabilizing the crystal lattice, and thereby improving both rate and cycle performance.
- The addition of aluminum ions through nano-alumina doping increases the battery voltage, thereby enhancing overall battery safety.
- Coating lithium cobalt oxide with nano-alumina enhances thermal stability, improves cycle performance, and increases resistance to overcharging. It also inhibits oxygen generation and LiPF6 decomposition, prevents direct contact between LiCoO2 and the electrolyte, and reduces electrochemical specific capacity loss, leading to an increased electrochemical specific capacity of LiCoO2.
- Modification of spinel lithium manganate material using nano-alumina results in a battery with a reversible capacity of 107mAh/g. It exhibits excellent cycling performance at 55°C for 200 cycles with a capacity retention rate exceeding 90%.
