Abstract: The factors which influence the safety of lithium batteries exist from the choosing of the cell materials to the using situation of the batteries, from the beginning to the end of a battery life, so the reasons are complicated. Reviewing the Cell material themselves, process of the manufacturing, design of the BMS (battery manage system) and the safety parts, together with working conditions form the factors which may be the barrier of safety. We analyzed the factors which influence battery safety, such as the crystal structure/electrode potential/character, the cell manufacture process/growing of SEI, integration and designing of the battery, the abusing like over-charging/discharging/harsh temperature/accident. Proposing the way (integration and design) to make a safer battery.

Key words: lithium battery, power, safety, influencing factor
