Smartphone chargers will soon be 24 times smaller thanks to French researchers. Their potency will also be increased significantly. We are talking about a converter capable of delivering 180W of power, for a volume 24 times smaller. From smartphone to PC, this technological feat could be used on a large number of devices.
Batteries are at the heart of our everyday objects and are naturally the subject of much research. Recently, a revolutionary anode technology capable of accelerating rapid recharging has been discovered. New work, by French researchers this time, in turn promises a technological leap in this area in the years to come. The CEA Tech Institute has indeed succeeded in developing a system making chargers 24 times smaller, all in increasing their power.
Current chargers, also called “inductor converters”, store electrical energy in the form of a magnetic field before returning it to the device at the indicated power. Only concern: energy losses are very important, while this technology requires the use of a considerable volume. To overcome this problem, the CEA researchers replaced the component at the origin of the magnetic field with a piezoelectric material (understand a material that deforms under the action of an electric field).
180W of power for 24 times less volume
A small change that brings impressive results. In addition to storing much more energy than the standard device, this material makes possible the development of miniature magazines of barely 1 mm thick. A feat that would allow, among other things, the direct integration of technology into smartphones and tablets to offer reverse recharging more efficient.

The researchers do not plan to stop there and plan to rfurther reduce the size of the set, by including it among other things in an integrated circuit. These claim that the system is capable of delivering a power of 180W, in addition to being compatible with 80% of devices on the market. We are therefore impatiently awaiting the applications that smartphone and PC manufacturers will make for their next products.
