AlLiMn2O4 Detailed Product Description
The Aluminum-Doped Lithium Manganese Oxide Target (AlLiMn₂O₄) enhances the performance of standard LiMn₂O₄ by incorporating Al³⁺ ions into the spinel lattice. This substitution mitigates Jahn-Teller distortions typically caused by Mn³⁺, thereby improving the material’s structural integrity during charge-discharge cycles. The addition of aluminum not only stabilizes the crystal structure but also increases resistance to phase transitions and capacity degradation, making it highly suitable for thin-film lithium-ion battery applications.
Key features include:
- Enhanced Structural Stability: Aluminum doping strengthens the spinel framework, reducing distortions and maintaining structural integrity over multiple cycles.
- Improved Thermal Stability: The modified composition offers greater resistance to thermal fluctuations, ensuring consistent performance.
