One of the most noticeable effects in loss of performance and capacity of thermal systems is produced by altitude. This causes that the density of a compressible fluid and the atmospheric pressure are considerably reduced, causing a decrease in electrical power and thermal systems. Given ... Read More
使用COMSOL Multiphysics计算了硅基锂离子电池在不同硅颗粒大小，电池放电倍率及固体电解质界面几何均匀性三个条件下SEI的稳定性。仿真结果表明，当硅颗粒半径从800 nm减小到600 nm和400 nm时，失效时间分别增加到原来失效时间的129%和165%。当结构缺陷深度比从0.6降低到0.4和0.2时，破坏时间分别增加到174%和237%。放电倍率方面，与0.1C相比，0.2C和0.3C下的失效时间分别延长至134%和239%。依此证明了减小硅颗粒粒径，人工设计结构均匀的SEI，采用较小倍率运行电池都是提升SEI稳定性的手段 Read More
