关于小动力锂电池，没有明确的定义，查百度是 " 中小型车辆、便携式设备、轻中型电动工具、智能家居产品等低能耗设备提供动力的可充电 电池 " ，它的特点是电压比较低，容量比较低，成本要求很敏感。主要的应用领域，电动二轮 / 三轮车、低空经济、游艇、机器人、工程机 械。天上飞的，地上跑的，水里游的，都纳入小动力电池范畴。 根据不完全统计，中国的电动二轮车保有量差不多 4 亿辆，如果按照每两年换一次，因为铅酸电池使用寿命将近 2 年，每两年换一次铅酸电 池，如果是 2 亿辆，每一辆电动电瓶车的平均电量 1.3 度电，那就是 260GWh ，每个月差不多有 1600 多万套。 260GWh 什么概念呢？ 1000 多亿的市场。 | | | 分 : 分 : 分 : 不 : | | | | | E 親 | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | | | 2015 0 2025 | | | | 国 12 | F 125 同 行 | | | | | | | | | 起点锂电行业年会暨锂电金鼎奖颁奖典礼 | | | | | | | ...
