Why are energy battery cabinets filled with nitrogen

Now, a group of researchers from the Changchun Institute of Applied Chemistry has outlined one way atmospheric nitrogen can be captured and used in a battery for next-generation energy storage systems. The "proof-of-concept" design reverses the chemical reaction that powers existing Lithium-nitrogen batteries.

The following is the analysis. The working principle of nitrogen cabinet is to fill the cabinet with nitrogen, gradually replace the original air in the cabinet, and then achieve a relatively anaerobic and dry storage environment.

Up until now, converting nitrogen has heavily relied on the energy – and capital–intensive Haber-Bosch process. In this process, H2 and energy is largely derived from fossil fuels, meaning large amounts of carbon dioxide are given off. The new battery could get around this problem.

Manuifacturers should avoid sealing problems, and intake valve failure in the N2 cabinet. Nitrogen cabinet is to fill the cabinet with nitrogen, gradually replace the original air then achieve a relatively anaerobic and dry storage environment.

Nitrogen cabinet is to regulate nitrogen injection into the cabinet, and achieve dehumidification and oxidation prevention. Nitrogen cabinet is widely used in semiconductor factory, crystal oscillator factory and precision component factory. It is mainly used for moisture-proof and oxidation protection.

“We have demonstrated that electrochemical N2 fixation in ambient conditions is possible with rechargeable Li-N2 batteries,” the authors explained. Instead of generating energy from the breakdown of lithium nitride into lithium and nitrogen gas, the battery prototype runs on atmospheric nitrogen in ambient conditions.
