Safety and reliability are the key concerns when determining the right power source for a medical device. Lithium-ion (Li-ion) batteries are often considered for their higher energy density, lighter weight, longer cycle life, superior capacity retention, and ability to withstand a broad range of ambient temperatures. However, with an increasing number of potentially dangerous incidents — including fires and explosions — from Li-ion batteries, quality assurance is more important than ever for error and risk prevention, particularly for medical devices that use these power sources. Having a holistic quality approach across the battery product lifecycle is essential for achieving safe, high-quality, and environmentally friendly products.
