In the lithium battery production workshop, installCombustible gas detectorIt is a key measure to prevent fire and explosion accidents, mainly targetingHydrogen gas (H?)、Electrolyte volatile organic solvents (VOC)Waiting for combustible gases. The following are specific installation plans and precautions:

detection target

• Hydrogen gas (H?)During the process of battery charging, discharging, and aging, precipitation may occur.

• Electrolyte solvent vaporEsters such as DMC, DEC, EC, etc. (flammable and explosive).

• Other combustible gasesBy-products such as methane (CH?) and carbon monoxide (CO).

• Selection of combustible gas detectors

• (1) Sensor type

• Catalytic combustion sensor(Catalytic)

• Applicable gasesMost flammable gases such as hydrogen, methane, VOCs, etc.

• advantageLow cost, high stability, suitable for routine testing.

  
  

• Infrared sensor (IR)

• Applicable gases：VOC、 Methane, etc.

• Not affected by hypoxic environment, long lifespan.
