How many Lithium-ion batteries do you think you have around you? Lithium-ion battery is widely used i n smartphones, electric cars, laptops, renewable energy storage plants, battery back up rooms, aircrafts, etc.
While it's helpful for our daily life, have you noticeed it can cause toxic and combustible gases? Let's see when they generate from it.
Gas Generations in Lithium-ion Batteries
First of all, it's the process of battery production. We go through various processes until the battery comes to us, and gases below are used and generated during the drying stage, the filling stage of the electrolyte, and the testing stage etc.
NMP (Solvent)
DMC, EMC, DEC (Electrolyte)
DCM (Dichloromethane)
Next, it's during the usage. When the Li-ion batteries are overcharged and short circuited, they're overheated and catch fires. Most of all, the overheating can cause the electrolyte in Li-ion batteries to vaporize toxic gases such as CO, CO2, HF. Especially, exposure to HF can cause Fluoride poisoning with stomach pain, weakness, convulsions, or death.
Also, small volumes of H2 can be generated during the charging cyde, and if this gas leaks, it can cause explosive environment Hydrogen gas is explosive at 4% by volume in air. Ventilation may be not a perfect solution as hydrogen gas is lighter than air and it can be accumulated into celling and highest structures.
What should we do to prevent this? SENKO is the solution.
SENKO has fixed gas detectors that ca detect gases in confined spaces that cannot be entered by humans. In addition, SENKO also has portable gas detectors that can be carried directly by humans and detect gases surround them.
