高性能锂离子电池正极材料的设计制备、结构与性能构效关系研究;电池失效分析,晶体结构分析及表征。

(1)提出仿建筑物“榫卯结构”的正极材料优化策略

高镍层状氧化物是最重要的主流锂离子电池正极材料之一,它在服役过程中的严重结构退化和快速容量衰减极大地限制了其在下一代高能量密度锂离子电池中的应用。通过材料合成工艺的创新设计,我们首次在富镍层状氧化物中引入尖晶石榫卯结构,从而显著抑制了其在充放电过程中的结构退化。同时,具有高离子电导率的尖晶石榫卯结构显著抑制了材料的首圈容量衰减,并显著提升了其电化学循环稳定性。

(2)提出“表面高熵化”的正极材料优化策略

通过Mg-Al-Eu共掺杂,在钴酸锂层状氧化物体系实现了表面高熵化结构的制备。该表面高熵层显著降低了晶格失氧和钴元素的溶解,进而抑制了CEI膜的过度生长和层状结构退化。同时,优化后的材料相变可逆性和热稳定性也大大增强。结果表明,表面高熵化的钴酸锂表现出优异的高压循环稳定性。这种表面高熵化策略为高压正极材料的开发提供了新途径。
