利用COMSOL Multiphysics®对锂电池进行容量衰减预测

李金东 [1], 吴旭 [1],
[1] 华中科技大学,武汉,湖北,中国

在能源危机和气候变化的背景下,电动汽车和混合动力汽车产业快速发展,锂离子电池在其中发挥着重要作用。锂离子电池使用过程中的容量衰减研究是该领域中的一个重要课题。锂锰氧化物(LMO)由于其经济、无毒害等优点,成为锂离子电池的常用阴极材料之一。有文献报道,在电解液中六氟磷酸锂分解产生质子的情况下,锂锰氧化物会发生分解,锰离子发生溶出并在阳极发生沉积,这是造成锂离子电池容量衰减的原因之一。本模型通过仿真上述过程,分析锂锰氧化物的分解与沉积对电池容量衰减的影响。使用COMSOL Multiphysics®进行建模,参考案例库中的锂离子电池容量衰减模型(Application ID ...

生命体系中,位于细胞上的各种离子通道精妙的调控着各种生理生化过程。以此为原型,各种各样的仿生纳米体系也被相继开发,其中,纳流二极管研究领域更是发展迅猛。然而,现有的关于纳流二极管的研究都是通过 pH,电压等外界刺激改变表面固定功能基团的电荷类型从而调节纳流二极管的方向,这大大限制了纳流二极管功能的调控自由度。于是,我们制造了一种通过光响应的同时可以进行 pH 调节的“即插即用”双向纳流二极管。该体系基于聚合物单纳米通道,通过化学接枝,利用光响应主客体作用原理实现“即插即用”功能。通过实验实现了实验设计,并利用理论模拟进行仿真分析。模拟过程使用 COMSOL ... Read More
