Lithium ion batteries can be found in an infinite number of applications today. In addition to mobile phones, laptops, tablets or cameras these kind of batteries can be found in vacuum cleaners, tools, vehicles, storage applications, and large energy storage devices for storing energy from solar cells. Because of their high efficiency, they are being used in more and more new applications that previously could not be operated by battery. Lithium ion cells are characterized by a high energy density. The useful life is several years. However, this is highly dependent on its use and storage conditions. Lithium ion cells are especially negatively affected by overcharging. Therefore, lithium ion batteries are often provided with a protection circuit that protects the battery from overcharging. Only compatible chargers should be used. Lithium is a chemical element and the lightest metal. It has two advantages for use in batteries. It possesses the largest negative voltage potential and is also the lightest element in solid form. Our Jauch experts advise you on choosing the right cell and design a lithium ion battery pack according to your special application.
