In recent years, China's energy storage power station market scale continued to expand, the growth rate is significant. By the end of 2024, the cumulative installed capacity of new energy storage in China reached 73.8GW/168.0GWh, an increase of more than 130 percent over the end of 2023. In the first half of 2024, the new domestic energy storage capacity reached 12.9GW/31.24GWh, with a year-on-year growth of 98%. These data show that China's energy storage power station market is in a stage of rapid development. The application scenarios of energy storage power stations are also expanding, covering many fields such as electricity, industry, energy, transportation, construction, communications and agriculture.

Most of them are lithium-ion battery energy storage technology. The proportion of power grid energy storage lithium-ion batteries will continue to increase in the future, and the development prospects of large-scale energy storage technology are incomparable. Due to the large potential of the positive and negative electrodes of the lithium iron phosphate battery, an organic electrolyte with a wide electrochemical window but a flammable organic electrolyte has to be used, which is easy to induce thermal runaway of the battery (the battery temperature is out of control and rises sharply), which brings serious safety hazards to the energy storage system.‌

Lithium battery thermal runaway will release a large amount of gas, different types of lithium-containing cathode material thermal runaway release of gas is very similar, the most important gases areH2、CO、CO2、CH4Wait.

Among them, the diffusion speed of hydrogen is the fastest. The following figure shows the chemical reaction mechanism of hydrogen generation process and lithium dendrite and polyvinylidene fluoride binder respectively.

Moreover, a series of safety problems of lithium batteries are also closely related to the growth of lithium dendrites, so the lithium evolution process can be detected by hydrogen detection, which can be used to monitor the safety status of the battery.

Recently, Japan's Figaro launched a hydrogen sensorTGS2616-C00, Fast response, low power consumption, small size,TGS2616-C00It contains a newly developed sensitive element, which is very little affected by interference gases such as alcohol, and has a high selectivity to hydrogen. Ideal for detecting changes in hydrogen concentration.

At the same time,TGS2616-C00The application circuit is also very simple.

Provide a stable heating voltage to the sensor, connect a fixed resistor voltage division in series, and sample the fixed resistor voltage division.

       TGS2616-C00Gas sensor incarnation "battery safety sentry" real-time monitoring of the initial release of thermal runawayH2Gas, accurately capture danger signals!0.1Second fast response, high temperature, liquid leakage, overcharge have no escape, prevent trouble from not "burning", whether it is a home energy storage station or a new energy power station, safety is no small matter! With science and technology for green energy escort, so that every degree of electricity are "stable" as Mount Tai.
