Article Synopsis
- - The study focuses on improving the performance of high energy density spinel LiNiMnO cathodes, which suffer from rapid capacity loss, by substituting magnesium for manganese to create LiNi0.5MgMnO using a microwave sol-gel method.
- - X-ray diffraction analysis showed that magnesium substitution alters the interstitial sites in the spinel structure, leading to improved electrical performance, particularly with a 3% substitution (x = 0.03), which enhances rate performance and cycling stability.
- - A higher substitution level (5%, x = 0.05) further boosts cycling performance, retaining 96% capacity after 500 cycles at high discharge rates, making it suitable for diverse applications and also indicating potential as
