From vehicles to energy storage, it is inseparable from the thermal runaway management of power lithium batteries

With the rapid increase in social electricity consumption year by year, the expansion of renewable energy, and the continuous development of new formats such as microgrids and new energy vehicle charging, the energy storage market has spawned more room for development. Industry professionals predict that the energy storage market will be another trillion-level market after new energy vehicles, energy storage-related technologies have become an efficient demand, and companies have been involved, of which the dynamic (intention) of power lithium battery companies is the strongest.

When the absolute safety of energy storage fire protection has been put on the agenda of the industry, and the power lithium battery as a companion product, it will be more rigorously tested in terms of safety management.

However, in recent years, the frequent fire accidents in global electrochemical energy storage stations have become a sharp sword hanging on the road of industrial development. In 2018, there were 23 energy storage power station fires in South Korea, resulting in the closure of 522 of 1490 energy storage projects in South Korea.

Experts believe that most of the fires in lithium-ion batteries are caused by thermal runaway. The higher the energy density of the lithium-ion battery material, the higher the safety risk and the greater the risk of thermal runaway. To avoid fire, it is necessary to start from the root cause, from the battery cell to the entire system to design the system, control and even avoid the occurrence of thermal runaway and thermal diffusion.

With the development of new energy vehicles, the development of electrochemical energy storage is also an inevitable trend, pay attention to battery safety is the primary task of the development of the industry, should accelerate the establishment of a comprehensive safety assurance system.

However, in the new energy vehicle application market, due to the rapid iteration of the energy density of power lithium batteries and other reasons, battery safety issues have attracted attention from all sides, which requires improving the safety level of energy storage power stations, strengthening the thermal runaway management of power lithium batteries and the fire early warning system functions of energy storage power stations.

At present, there are not many companies with similar mature experience in the market, and energyevoke counts as one.

The future development of energy is bound to be an era of diversification. We predicted the safety of fuel lithium batteries in advance: “To do small industries in the field of segmentation, we must also observe the general trend of the industry, and the choice of direction is very important.” The prospect of hydrogen fuel lithium batteries is very impressive, energyevoke will also turn the research and development goals to fuel lithium battery safety, and strive to develop a set of power lithium battery management, hydrogen fuel lithium battery management, energy storage management complete intelligent security solutions. ”

In the future, the energy storage industry will show a decentralized structure, and more and more companies will pour in. Through technological development and cross-border integration, hydrogen fuel lithium batteries, lithium-ion batteries, energy storage safety and other aspects will further achieve intelligent integration, this cause has a long way to go, energyevoke will continue to exert efforts.
