Rechargeable lithium-ion batteries are popular power sources, prone to combusting when rare abnormalities occur. This case study describes how Phillips-Medisize further enhances the safety of lithium ion cell technology. As a result, short-circuited lithium ion batteries smolder and extinguish, rather than ignite and explode. The solution has the potential to help minimize harm to property and lives, while significantly enhancing the safety of devices that run on rechargeable lithium-ion batteries. View case study.
