Samsung innovates the li-ion battery

 It’s undeniable that the built-in batteries we have in our smartphones are the weakest link in all the awesomeness of high pixel density screens, octa-core processing and impressive cameras that rival compact cameras. You can all the best hardware, but without power, it’s just a brick, and a mobile phone isn’t deserving of the name “mobile phone” if it has to be attached to the wall or a power bank most of the time. It just isn’t mobile.

Seeing the problem, Samsung develops a new technology, creating a silicon cathode material for coating high crystal graphene on a silicon surface to usher in an energy density that is nearly two times more than existing lithium batteries. Current lithium batteries were developed and commercialized by Sony in the 90s, and have slowly been getting better and better, but the material itself has its limitations.

Most of the development of high-capacity battery materials has been done in the US, but there is a major technological problem that shortens the life of a lithium battery from constant charging and discharging. The R&D center of Samsung Electronics has succeeded where no one else has, developing a high-density and very durable cathode material by coating the strong and conductive graphene on the surface of the silicon, in order to create a type of protective shell around the silicon.

Samsung has been working on improving battery capacity to make itself stand out from the competition, and this technology could be its ticket.

Industry watchers have said that the technology will need around two to three years to reach commercialization.

Pokdepinion: This is all good for the world. We just shared news of innovation in li-ion batteries for home and electric car applications and were left hoping for innovation in the mobile world too. Given that Samsung also has joined the “sealed battery” crowd, it would be wise to improve on the battery since users can’t swap out their dead batteries for a fully charged one — something many proponents of Samsung phones claim to be among the pros of using a Samsung smartphone but I have never seen anyone do it for real. We are all for longer-lived smartphones!
