A pleasant surprise from Samsung's research team: The evolution of our mobile devices seems to give us more and more opportunities every year, but is still limited by a relatively old technology. The batteries they usually use only last one day.
Samsung's research team is working on something that can almost double the battery life, substantially increasing the density of stored energy.
Scientists have announced that it is possible to increase the lifetime of a battery by 1,8 times.
Neowin reports that the researchers reported that they were able to have these results in their laboratories.
The Samsung team of scientists used silicon (silicone) anodes instead of traditional toners. This approach has shown positive results, but the problem presented was that silicon expands and contracts during charging and discharging the battery.
To address this, the Samsung team has created a process for the development of silicon layer graphene cells that can be adapted to prevent the expansion of silicon.
"The graphene layers on the silicon surface keep the volume of silicon between the adjacent graphene layers. When the technique is combined with a lithium cobalt cathode, the silicon-free graphene carbide allows the energy storage cells to reach the volumetric energy densities of 972 and 700 Wh L-1 in the first and 200th cycles, respectively, 1,8 , 1,5 and XNUMX times higher prices than those of today's commercial lithium-ion batteries. "
The technology sounds promising, but you have to keep in mind that this is a research project. In order to have a commercial application, it will take a lot of testing time to avoid having unpleasant phenomena, such as a device ignition in our pocket.
