Prismatic Battery Cell

What Is a Prismatic Battery Cell

Prismatic battery cell is encased in aluminum or steel for stability. Jelly-rolled or stacked, the cell is space-efficient but can be costlier to manufacture than the cylindrical cell. Modern prismatic cells are used in the electric powertrain and energy storage systems.

Prismatic Battery Cell Handling Precautions for Safe Use

Danger
● Take care not to touch the chemicals and electrolyte from inside the batteries directly. Since alkaline solution is used in this battery system, there are risks of not only damage to cloth and skin resulting from adhesion of the solution, but also loss of eyesight if the solution gets into the eyes.
● In case of such an emergency where the solution gets into the eye, wash immediately with plenty of water and receive medical treatment from a doctor.
● If the solution adheres to the skin and/or clothes, wash with water and consult a doctor.
● These batteries are equipped with a mechanism that releases excessive internal pressure to prevent explosion. During charge, short-circuit, and overdischarge of batteries, the internal pressure may rise abnormally and result in electrolyte leakage via venting. However, in extreme circumstances, the vent mechanism may not work normally, and explosion can occur.
● In the event of short-circuit, battery surface temperature may rise above 100°c.
2. Warning
● Always take care to insert batteries correctly according to the designation of polarity (⊕ and ⊖) on the batteries and the equipment.
● Batteries which are incorrectly placed into equipment may short-circuit, or be charged. This can result in a rapid temperature rise and venting leading to leakage and explosion.
● Do not short-circuit batteries.
● When the positive ⊕ and negative ⊖ terminals of batteries come into direct contact with each other via mixing or storing batteries together, short-circuit can occur. If batteries are short-circuited, excess current flows instantaneously, which leads to heat generation, damaging the internal structure of the batteries, and causing risk of electrolyte leakage, explosion, etc.
● Do not charge batteries.
● These batteries are not rechargeable. Charging may result in electrolyte leakage and/or damage. If charged, gas can be abnormally generated inside of the cell, resulting in increased internal pressure, which may cause electrolyte leakage and/or damage of cell. If the charging current is excessively large, the cell could be at risk of explosion due to gas generation. When unused cells are charged, the risk of electrolyte leakage, damage, explosion, etc. Is especially higher.
● Do not overdischarge batteries.
● When a battery is kept connected with an electrical circuit even after the equipment is not in use (due to forgetting to switch off the equipment or possible misuse), the battery will continue to supply energy and reach an overdischarged state. This can result in internal gas generation and electrolyte leakage or explosion. When two or more batteries are connected in series and are overdischarged, the voltage may reach zero or minus volts (polarity change) and such a condition may increase the risk of electrolyte leakage and explosion.
● Do not discharge forcibly.
● When batteries are discharged by an external power supply, the battery voltage becomes extremely low. This can cause internal gas generation and it may increase the risk of electrolyte leakage and explosion.
● Do not mix batteries.
● When replacing batteries, replace all of them at the same time with new batteries of the same brand and type. When batteries of different kinds are used together, or new and old batteries are used together, some batteries may be overdischarged due to a difference of voltage or capacity. This can result in risk of leakage and explosion.
● Exhausted batteries should be immediately removed from the equipment and disposed of.
● When discharged batteries are kept in equipment for extended periods, electrolyte leakage may occur causing damage to the equipment.
● Do not heat batteries.
● If batteries are heated, the resin used in the batteries may melt and deform due to temperature rise, and electrolyte leakage and explosion may occur.
● Do not directly solder batteries.
● When a battery is directly soldered, it may be damaged by heat. This may result in leakage, explosion, etc.
● Do not disassemble batteries.
● Improper disassembly of a battery may result in injury of the fingers, damage to the eyes and skin resulting from leakage of chemicals inside the battery.
● Do not deform batteries.
● Batteries should not be dropped, crushed, punctured, or otherwise damaged. Such abuse may result in leakage, heat generation or explosion.
● Do not dispose of batteries in fire.
● When batteries are disposed of in fire, the heat build-up may cause explosion.
● Do not allow children to replace batteries without adult supervision.
● Keep batteries out of the reach of children.
● Keep batteries which are small enough to be swallowed out of the reach of children. In case of ingestion of a cell or battery, seek medical assistance immediately.
● Do not modify batteries.
● Modification of batteries may cause blockage of the pressure relief vent mechanism and may increase the risk of explosion.
● Store unused batteries in their original packaging and keep them away from metal objects which may short-circuit them.
● Remove discharged batteries from equipment.
● Remove batteries from equipment when they do not work, or when a long period of disuse is anticipated (e.G. Video cameras, camera flashes, etc.). A battery partially or completely exhausted may be more at risk of leakage than an unused battery.
