HEV Lithium Ion Battery Cell

SECTION 2: Hazards identification

For the battery cell, chemical materials are stored in a hermetically sealed Aluminum case, designed to withstand temperatures and pressures encountered during normal use. As a result, during normal use, there is no physical danger of ignition or explosion and chemical danger of hazardous materials' leakage. However, if exposed to a fire, added mechanical shocks, decomposed, added electric stress by miss-use, the battery cell case will be breached at the extreme, hazardous materials may be released. Therefore, addition of electrolyte is forbidden after sealing the battery cell to maintain sealability. Moreover, if heated strongly by the surrounding fire, acrid gas may be emitted.

Most important adverse effects

and effects

Potential health effects

Inhalation: The steam of the electrolyte has an anesthesia action and stimulates a respiratory tract. Skin contact: The steam of the electrolyte stimulates a skin. The electrolyte skin contact causes a sore and the stimulation on the skin. Eye contact: The steam of the electrolyte stimulates eyes. The electrolyte eye contact causes a sore and the stimulation on the eye. Especially, substance that causes a strong inflammation of the eyes is contained.

Environmental effects

Since a battery cell remains in the environment, do not throw it into the environment. ・Specific hazards: If the electrolyte contacts with water, it will generate detrimental hydrogen fluoride. Since the leaked electrolyte is flammable liquid, do not bring close to fire.
