MSDS For LiFePO4 Battery Pack – Semco University

msds-for-lifepo4-battery-semco-university
Introduction

A MSDS For LiFePO4 Battery Pack is currently the most convenient and efficient way to store electricity. The storage of electricity has always been a scientific and technical challenge. In this article, you’ll find the technology behind the Lithium Iron Phosphate battery (LiFePO4), also called LFP battery.

Hazards Identification

With normal usage, there is no contact with the electrolyte and no hazard exists. If exposed to high temperature or fire, cells may leak electrolytes and in extreme cases explode. The vented gas may contain among other Hydrogen Fluoride.

First Aid Measures

With normal operating condition, contents of the cells are in sealed (polymer pouch/metal can or cylinder) condition and pose no threat to the user. Exposure to the cell internal content happens under abusive conditions.
Inhalation: Contents of open battery may cause respiratory irritation. Move to fresh air immediately and seek medical attention.
Skin: Contents of open battery may cause skin irritation. Wash skin with a copious amount of soap and water.
Eye: Contents of open battery may cause eye irritation. Flush eyes immediately with water for at least 15 minutes and seek medical attention.
Ingestion: Seek medical attention immediately. Induce vomiting.

Fire Fighting Measure

In case of fire, use CO2 or CLASS D fire extinguisher. In case battery burns with other combustible, use corresponding fire extinguisher. Corrosive fumes may be present during fire, use protective equipment (gloves, breathing apparatus, goggles, etc.). Gases from the burning fire will include hydrogen fluoride, carbon oxides, hydrocarbons among others.

Accidental Release Measures

Battery material is enclosed in either metal casing or laminate and does not release easily under normal usage. Under abuse conditions such as puncture, high heat exposure, electrical abuse electrolytes containing vinyl chloride salt in organic solvent may leak out. See section 4for first aid measure. Seek medical attention.

Handling & Storage

Storage: Store within the recommended temperature limit of the battery (read instruction manual for specific limits). Do not expose to high temperature (60°C/140°F). Avoid short circuit of the battery. The battery short circuit may cause the release of gas and may pose a burn hazard.
Handling: Do not disassemble, crush or otherwise abuse the battery. Do not open the battery.
Charge: Charge only with dedicated/specific chargers designed for this battery.
Discharge: Discharge within the temperature limits of the battery detailed in the specification.
Caution: This battery when abused may pose a fire, explosion, and severe burn hazard. Handle with caution.

Conclusion

LiFePo4 batteries only supply and accept DC (direct current). One LFP battery is the assembly of multiple prismatic LiFePo4 cells of 3.2V. Therefore, a 12V LiFePo4 battery is made of 4 prismatic battery cells in series. A 24V LiFePo4 assembles 8 prismatic cells.
