Where the battery is damaged, it can overheat and catch fire without warning. Batteries should be checked regularly for any signs of damage and any damaged batteries should not be used. The incorrect disposal of batteries – for example, in household waste – can lead to batteries being punctured or crushed.
Battery power has been around for a long time. The risks inherent in the production, storage, use and disposal of batteries are not new. However, the way we use batteries is rapidly evolving, which brings these risks into sharp focus.
This article aims to answer some common questions of public concern regarding battery safety issues in an easy-to-understand context. The issues addressed include (1) electric vehicle accidents, (2) lithium-ion battery safety, (3) existing safety technology, and (4) solid-state batteries.
Normal operation A high percentage of accidents occurs at the time when there is no any obvious abuse. The causal factors for these accidents are mainly the aging of the battery system and the increased inconsistency of the individual cells in a battery pack. The aging of the battery pack includes the aging of the battery cells and modules.
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.
If the voltage of any battery cell cannot be effectively monitored by the management system, there will be risks of its overcharging. Since excess energy is stored into the battery, overcharging is very dangerous. Typically, all batteries are first charged to a specific SOC, but some batteries initially have higher SOC before charging.
