Why do batteries fail?

Why batteries go bad Rechargeable batteries are found in a range of everyday devices, from shavers and laptops to cars and airplanes. Over time, these batteries can fail, either through a gradual loss of charge or through the inability to work under tough environmental conditions, leading to more catastrophic failures that cause fires or explosions. Palacin and de Guibert review such failures and suggest that, although often chemistry-specific, common causes can be found. They also look at ways to enhance battery lifetime, such as through improved battery management systems, which are needed for advanced rechargeable batteries.
