【摘要】 尖晶石结构正极材料LiNi_0.5Mn_1.5O₄因具有理论比容量高、比能量大、放电平台高（⁴.7 V）、价格低廉等优点而备受关注。但该材料循环性能和倍率性能不佳,制约着材料的推广应用。主要综述通过掺杂、包覆、形貌控制等手段来提高该材料电化学性能的最新研究进展,旨在为提升该材料性能的相关研究提供参考。更多还原

【Abstract】 Spinel LiNi_0.5Mn_1.5O₄ has been paid extensive attention owing to its high theoretical capacity, high energy density,high discharge platform（4.7 V） and low price. However, the rate capability and cycle performance of spinel LiNi_0.5Mn_1.5O₄ are not good enough. In order to address these issues, the materials have been improved by modification. The recent researches on modification of LiNi_0.5Mn_1.5O₄ cathode materials were reviewed, such as doping, surface coating and morphology controlling.更多还原
