Sony developing new smartphone battery with 40 percent longer life

Sony Mobile already has a strong reputation when it comes to the battery longevity of its mobile products. The good news is that Sony is looking to take that a step further in the future, with the development of new high-capacity rechargeable battery for smartphones.

The new battery uses a sulphur (S) compound as the electrode material allowing Sony to increase energy density per volume from the current 700Wh/L to 1,000Wh/L. This means that battery life capacity will increase by up to 40% compared to its lithium-ion equivalents.



Sony is developing both lithium-sulphur (Li-S) and magnesium-sulphur (Mg-S) batteries. However, before you get too excited and start factoring this into your next Xperia ‘wishlist’, Sony doesn’t plan to commercialise this technology until 2020.
