According to a report in the Korean news site The Elec, the company is reportedly leveraging technology developed by its battery making offshoot Samsung SDI.
In order to fit batteries into the small housing contained in smartphones, battery makers currently use a technique that relies on ‘rolling’ the batteries.
But in developing its EV batteries Samsung SDI has developed a ‘stacking’ technique, which is uses even less space than rolling.
According to The Elec, this new technique could increase the energy density of smartphone batteries by as much as 10 percent.
In the case of the latest Galaxy S smartphone this could increase battery capacity from 5000mAh currently to more than 5500mAh, without any need to increase the size of the battery housing.
While there is no word on when these new batteries might find their way in to new Samsung smartphones, The Elec quoted industry sources as saying that Samsung SDI has already decided to introduce a stacking-type production process to the small pouch-type battery production line at its plant in Cheonan, South Korea.
Once up and running, it will be the first time that Samsung SDI has produced small batteries in the stacking process.
