对于锂离子电池包制造商来说，针对电池供电系统构建安全且可靠的产品是至关重要的。电池包中的电池管理电路可以监控锂离子电池的运行状态，包括了电池阻抗、温度、单元电压、充电和放电电流以及充电状态等，以为系统提供详细的剩余运转时间和电池健康状况信息，确保系统作出正确的决策。此外，为了改进电池的安全性能，即使只有一种故障发生，例如过电流、短路、单元和电池包的电压过高、温度过高等，系统也会关闭两个和锂离子电池串联的背靠背（back-to-back）保护MOSFET，将电池单元断开。基于阻抗跟踪技术的电池管理单元（BMU）会在整个电池使用周期内监控单元阻抗和电压失衡，并有可能检测电池的微小短路（micro-short），防止电池单元造成火灾乃至爆炸。
锂离子电池安全
过高的工作温度将加速电池的老化，并可能导致锂离子电池包的热失控（thermal run-away）及爆炸。对于锂离子电池高度活性化的含能材料来说，这一点是备受关注的。大电流的过度充电及短路都有可能造成电池温度的快速上升。锂离子电池过度充电期间，活跃得金属锂沉积在电池的正极，其材料极大的增加了爆炸的危险性，因为锂将有可能与多种材料起反应而爆炸，包括了电解液及阴极材料。例如，锂/碳插层混合物（intercalated compound）与水发生反应，并释放出氢气，氢气有可能被反应放热所引燃。阴极材料，诸如LiCoO2，在温度超过175℃的热失控温度限（4.3V单元电压）时，也将开始与电解液发生反应。
锂离子电池使用很薄的微孔膜（micro-porous film）材料，例如聚烯烃，进行电池正负极的电子隔离，因为此类材料具有卓越的力学性能、化学稳定性以及可接受的价格。聚烯烃的熔点范围较低，为135℃至 165℃，使得聚烯烃适用于作为热保险（fuse）材料。随着温度的升高并达到聚合体的熔点，材料的多孔性将失效，其目的是使得锂离子无法在电极之间流动，从而关断电池。同时，热敏陶瓷（PCT）设备以及安全排出口（safety vent）为锂离子电池提供了额外的保护。电池的外壳，一般作为负极接线端，通常为典型的镀镍金属板。在壳体密封的情况下，金属微粒将可能污染电池的内部。随着时间的推移，微粒有可能迁移至隔离器，并使得电池阳极与阴极之间的绝缘层老化。而阳极与阴极之间的微小短路将允许电子肆意的流动，并最终使电池失效。绝大多数情况下，此类失效等同于电池无法供电且功能完全终止。在少数情况下，电池有可能过热、熔断、着火乃至爆炸。这就是近期所报道的电池故障的主要根源，并使得众多的厂商不得不将其产品召回。
