许多企业的电池产品能够实现低温下正常放电，但在同样的温度下，实现正常充电就比较吃力，甚至无法充电，当Li+嵌入石墨材料时，首先要去溶剂化，这个过程会消耗一定能量，阻碍了Li+扩散到石墨内部；相反，Li+在脱出石墨材料进入到溶液中时，会有一个溶剂化过程，而溶剂化不消耗能量，Li+可以快速脱出石墨。因此，石墨材料的充电接受能力要明显逊色于放电接受能力。
低温环境下，锂电池充电有一定的风险。因为随着温度的降低，石墨负极的动力学特性进步一变差，充电过程中，负极的电化学极化明显加剧，析出的金属锂容易形成锂枝晶，穿破隔膜并导致正负极短路。
尽量避免锂离子电池在低温下充电。当电池必须在低温下充电时，需要尽可能选择小电流（即慢充）对锂离子电池进行充电，并在充电后对锂离子电池进行充分搁置，从而保证负极析出的金属锂能够与石墨反应，重新嵌入到石墨负极内部。
业内企业及科研机构对电池耐低温性能的探索和攻关，多着眼于对现有正负极材料的工艺改进，以及通过提高电池的局部环境温度为电池在低温下工作创造条件。随着的技术的进一步发展，锂电池在低温环境下将有进一步的突破。
