Lithium ion battery

SECTION 2: Hazards identification

and Safety Precautions Classification according to WHS General Remarks  Within the battery, more precisely within the cells, chemical materials are enclosed in a hermetically sealed metal or metal laminated plastic case, designed to withstand temperatures and pressures occurring during normal use. As a result, during normal use, there is neither a physical danger of ignition or explosion nor a chemical danger due to leakage of hazardous materials. Classification according to GHS There is no requirement for classification according to GHS for Lithium ion rechargeable cells or batteries since they are considered as articles Description of possible hazards If the battery is exposed to a fire, to increased mechanical shocks, to increased electric stress by misuse or is damaged, the gas release vent will be opened. The cell or battery case will be breached in the worst case and hazardous materials may be released If the battery is heated strongly (e.g. by fire), acrid gas may be emitted When damaged cells or batteries are exposed to water, the formation of explosive gases (hydrogen) is possible In general, contact with substances of leaking cells or batteries can pose a danger to personal health and the environment. For this reason, when coming into contact with cells or batteries with a conspicuous appearance (leaking substances, deformed, discoloured, dented or the like), sufficient body and breathing protection is required Lithium cells or batteries can react very severely in combination with fire. This can result in ejection of components from the cells or batteries with considerable force Lithium cells or batteries can still represent a source of danger even when thought to be discharged, since they can deliver a very high short-circuit current Precautionary statements - Prevention When recharging cells or batteries, never use chargers which are unsuitable for the cell/battery type Use the charging process tailored to the respective cell type of a rechargeable battery Avoid deep-discharging of the cells/batteries Do not use deep-discharged cells/batteries again Do not short-circuit cells/batteries Do not inflict mechanical damage (puncturing, deforming, disassembling etc.) Do not heat them above the permitted temperature or burn them Keep cells/batteries away from small children Avoid excessive charging voltages and overcharging Observe cells or batteries regularly for unusual warming, odour, discolouration or deformation during charging, use and storage

Storage

 Always store cells or batteries in a dry and cool place.

2.1 Classification of the substance or mixture

 There is no requirement for classification according to GHS for Lithium ion rechargeable cells or batteries since they are considered as articles. Description of possible hazards  If the battery is exposed to a fire, to increased mechanical shocks, to increased electric stress by misuse or is damaged, the gas release vent will be opened. The cell or battery case will be breached in the worst case and hazardous materials may be released.  If the battery is heated strongly (e.g. by fire), acrid gas may be emitted.  When damaged cells or batteries are exposed to water, the formation of explosive gases (hydrogen) is possible.  In general, contact with substances of leaking cells or batteries can pose a danger to personal health and the environment. For this reason, when coming into contact with cells or batteries with a conspicuous appearance (leaking substances, deformed, discoloured, dented or the like), sufficient body and breathing protection is required.  Lithium cells or batteries can react very severely in combination with fire. This can result in ejection of components from the cells or batteries with considerable force.  Lithium cells or batteries can still represent a source of danger even when thought to be discharged, since they can deliver a very high short-circuit current.
