Samsung will improve the autonomy of its smartphones thanks to batteries inspired by electric cars

Samsung would prefer to improve the autonomy of its smartphones by equipping them with a battery technology that has so far only been used in the automotive industry. The size of the batteries of future smartphones could thus increase significantly.

Samsung SDI, a group company specializing in the production of batteries, has started production of the fifth generation of batteries for electric vehicles. Unlike traditional batteries, new accumulators will use a stacking method rather than the usual “jelly roll” method, as you can see in the image below.

Switching to a stacked design similar to that used in electric car batteries could lead to an increase of 10% or more in capacity of a battery of equivalent size. This is the first time that Samsung plans to use stacking technology in smaller batteries for phones, instead of large cells in electric vehicles, and the company is reported to have already set up a production line for these batteries in Korea, as well as a test line in China.

The Galaxy S23 could see its autonomy increase

If Samsung came to use this new technology in its next high-end smartphone, the Galaxy S23, it could see its autonomy greatly increased. Indeed, it requires, for example, the Ultra model to use a battery 10% larger than the Galaxy S22 Ultra, that is to say to 5500 mAh, without the smartphone becoming thicker.

For its part, Xiaomi also announced new technology last year promising a 10% increase in battery capacity for the same size as previous generations. For this, the Chinese manufacturer has in particular increased silicon content of electrodes and used improved packaging technology that shrinks and bends driver circuitry.

Adopting a stacked design for the battery could also allow manufacturers toimprove the fast charging power of their devices. For example, they could adopt a new technology recently developed by researchers, capable of fully recharging a battery in just 5 minutes.
