Battery Container Failures

摘要

Many industrial and consumer products rely on battery power, with product failure inevitable if the battery container cracks. Electrolyte damage to surrounding equipment can be severe owing to the corrosive properties of most electrolytes. Failure of the container can be caused by internal or external problems, such as explosions of excess hydrogen gas or by external impacts. However, many problems are exacerbated by poor design of the container, including moulding under inappropriate conditions or by the presence of severe stress concentrations. Several case studies are described in which one or more of these factors caused product loss or personal injury.
