Samsung Unveils Tech That Can Double Lithium-Ion Battery Capacity

Currently more than 80 per cent mobile users are using smartphones in all over the world and they are pretty satisfy and happy with the features and operations of device. But still the major concern of smartphone owners is the battery life of smartphones. If we believed on the latest report which was published last week in a journal, so there is way to double the capacity of lithium-ion batteries.

Report published by the researchers of Samsung claims that their new technology will enable the batteries to provide 1.5 to 1.8 time’s higher capacity in comparison of commercial lithium-ion batteries, which we are using in present. In the process to enhance the battery life, Samsung has come up with brand new coating technique only for battery cathodes which promise to overcome from the limitations of lithium ion batteries. According to published report in Nature Communications, this new battery technology will employ the use of graphene on the surface of silicon and it will offer the volume expansion, which will play vital role in the extended battery life.

The published report explains, “Here we are reporting the growth of grapheme directly over the silicon nano-particles with or without silicon carbide formation as the layers of graphene anchored onto the surface of silicon to accommodate the volume expansion for silicon with the help of a sliding process between the adjacent layers of graphene. When it paired with a lithium cobalt oxide cathode (commercial), so the coating of silicon carbide free graphene allow the cell to reach on the maximum volumetric energy densities, which is 972 and 700 Wh l-1 respectively however; the final result is 1.8 to 1.5 times higher capacity in comparison of commercial lithium-ion batteries, which we are using in present.

According to the tech experts and researchers the new technology of lithium-ion batteries will deliver the extended battery life however; soon it will be available as commercially viable option. The observation of researchers suggests that layered structure of graphene is two-dimensional and its integration with silicon and silicon carbide-free is able to serve as a prototype when it comes to advancing silicon anodes as commercially viable technology”.

Samsung, a consumer electronics giant located in South Korean acknowledge that this new technology will make the batteries less competitive in the cycle life due and volumetric energy density because of additional discharge cycles, however; researchers are still working hard to improve the effectiveness of these new batteries and it’s fair to say that currently we shouldn’t expect double the battery life in upcoming Galaxy Note 5 and Galaxy S7. As per experts, it will help the Samsung to get the desired boost in smartphones and laptop segments as users prefer to get more battery life for their devices.

Apart from that last year, researchers from US have developed an advanced or smart lithium-ion battery, which warn or alert the users from potential overheating as well as fire. This technology was designed for the traditional lithium-ion batteries and currently billions of laptops, tablets, cell phones and other electronic devices are using these technologies along with growing number of airplanes and cars.
