Li-ion battery replacement boasts 40% more capacity
Lithium-ion rechargeable batteries are used in virtually all portable devices now, thanks to their high energy density and better charging characteristics than NiCad and NiMH batteries. Many companies are researching ways to improve current types of lithium-ion batteries and looking for alternatives with even better characteristics. According to the Nikkei Technology website, Sony is working on the development of a Li-ion replacement with much higher energy density.
 
Sony expects to have a replacement ready by 2020, using a sulphur composite as the electrode material. It should have 40% higher energy capacity than current Li-ion rechargeable batteries. Two types are currently being developed: a lithium-sulphur (LiS) rechargeable and a magnesium-sulphur (MgS) rechargeable.
 
Sony is one of world’s largest manufacturers of lithium-ion batteries and supplies batteries for countless smartphones, tablets and laptops. The company launched the first commercial Li-ion battery in 1991.
