为实现失效磷酸铁锂(LiFePO_(4))电池正极材料的回收和再利用,采用仪器分析和表征方法,研究LiFePO_(4)正极材料失效前、后的理化性质。结果表明:失效后LiFePO_(4)电池正极材料中含有大量的Fe、P、Ni,少量的Cu、Co和微量的F元素,晶相结构未发生明显改变,Fe主要以Fe^(2+)和Fe^(3+)形式存在;LiFePO_(4)电池正极片失效后表面呈现不规则的波浪状缺陷和坑状凹陷;在失效过程中,LiFePO_(4)正极材料颗粒表面产生裂纹,破碎后形成的小颗粒变得黏连、杂乱和团聚,降低正极材料的电化学性能;失效后颗粒表面出现的约20 nm厚的PVDF膜结构影响颗粒表面的疏水性,降低浮选效率。

A distributed optimization problem with Markovian switching targets and stochastic observation noises is considered in this paper. In order to solve target following and renewable following for microgrid(MG) optimal power balancing, and to attenuate observation noises simultaneously, distributed optimization algorithms are developed. The interaction between observation noises and Markovian switching targets may introduce a fundamental tradeoff in reducing the optimization errors and choosing the step size. Furthermore, under infrequent Markovian switching assumptions, the mean-square optimization error bounds, the switching ordinary differential equation(ODE) limit, and the asymptotic distributions of the optimization errors are established rigorously and comprehensively. A simulation example on a DC MG is presented to show the main results of the paper.
