In theory, power lithium battery is safer than lithium manganate / ternary battery, but in the actual use process, due to the production process control problem of power lithium battery, the consistency of power lithium battery circuit from material to battery is not as good as lithium manganate and ternary battery. Although in recent years, the electric vehicle fire incident official did not give an authoritative conclusion, but we can not simply say that these are accidental events, it can be said that there are many disadvantages in the quality of power battery. In the market economy, enterprises tend to pursue the interests of maximization, many enterprises tend to only focus on the sales of batteries, but not the battery quality itself. Enough attention has been paid to the battery production process, lack of strict control and detection measures. On the other hand, to use the power battery as the main power of the car, we need to concentrate dozens of kilowatt hours of electricity into a small container. In this case, to ensure the safety of the battery, we need not only high-quality raw materials, but also high technical requirements in the structural design of the battery and the battery pack. In addition, the use environment of the power lithium battery is also affected. The important factor of its safety, in the case of extremely high or low temperature, the current technology can not guarantee the safety performance of battery 100%, so before the technology can not reach the perfect, the safety of power lithium battery is relative. At this stage in China, due to the low labor cost in the past few years, it provides a good development opportunity for the processing of power lithium battery. With the rise of labor cost, the power lithium battery industry in China is facing the challenge of transformation, which requires the battery manufacturers to change their metamorphosis and thinking, from only looking at the short-term, quantity to long-term and quality.

Although at present, the power lithium battery can not guarantee safety 100%, but with the progress of technology, these short boards will be overcome gradually, and the power lithium battery market will usher in the spring of rapid development.
