Batteries can pose significant hazards, such as gas releases, fires and explosions, which can harm users and possibly damage property. This blog explores potential hazards associated with batteries, how an incident may arise, and how to mitigate risks to protect users and the environment.
An overview of battery safety issues. Battery accidents, disasters, defects, and poor control systems (a) lead to mechanical, thermal abuse and/or electrical abuse (b, c), which can trigger side reactions in battery materials (d).
The external environment (which controls the temperature, voltage, and electrochemical reactions) is the leading cause of internal disturbances in batteries . Thus, the environment in which the battery operates also plays a significant role in battery safety.
When these batteries are poorly manufactured, overcharged or over discharged, incorrectly handled and/or connected, or exposed to excessive mechanical and physical stress, conditions may arise and lead to thermal runaway that in turn may lead to the venting, leaking, explosion and/or fire of the battery cell or pack.
Use of a damaged battery may lead to thermal runaway and subsequent fire. After the impact/accident, if the battery is not hot and/or leaking or smoking, disconnect the battery. Remove the battery from the equipment wearing gloves, goggles/safety glasses and lab coat (if available).
Overcharging and overdischarging of batteries should be avoided at all costs. Short circuits cause a great reduction in battery capacity. With each shorted cell, battery capacity is reduced by a percentage equal to one over the total number of cells.
