Abstract: 5.5Ah cylindrical Al-plastic film LiMn2O4-based lithium ion battery for E-bike was developed. These batteries exhibit good performance in rate discharge, cycle life and at high and low temperatures. The cells pass the safety test of GB/T 18287-2000 without any fire or explosion. The cells were stored for 3 months after discharging to 3.0V, and bulge appeared on the cell surface. With several cycles, the bulge disappeared without significant performance decay. The 10.8V/5Ah battery pack (3 cells in series) retain 82% of the initial capacity after 500 cycles at 1C, 100% DOD.

摘要: 研制成功了电动自行车用5.5Ah圆柱型铝塑膜锰酸锂电池,它具有良好的倍率、循环、高低温特性。单体电池通过了GB/T 18287—2000的安全试验,所有试验中电池不起火、不爆炸。将单体电池放电到3.0V,然后搁置3个月,电池出现“气胀”,经过循环,“气胀”消失,电池性能没有发生明显的变化。10.8V/5Ah电池组1C,100%DOD循环500次,容量保持在82%。
