Sunvault Energy Inc. and Edison Power Company have joined forces in creating a prototype for a smartphone battery case that they say will be the “best performing” one in the market upon release. Using graphene energy storage technology it is capable of providing the smartphone with 5000 mAh (milliamp hours) and can fully charge in only three minutes without generating any significant heat to the device. The battery case will also be have the “attributes of both a battery and a supercapacitor.” It will be significantly lighter compared to existing models on the market. The first prototype will be for the iPhone, but models will also be made for Samsung, Lenovo, LG, Huawei, and Sony. A Kickstarter campaign will be launched so that users can pre-purchase the pack before release.
Graphene, which is carbon-based, is stronger than steel and can conduct electricity better than copper. It is suitable when it comes to advanced energy storage since it has a high surface area and its resistance to electrical charge is low. Since it is carbon-based, it is safe and poses no threat to the environment. With that said, graphene based batteries will be the safer and more environmentally-friendly choice compared to Lithium batteries. As mentioned, the battery case will have the attributes of a supercapacitor, making it able to discharge high currents in a short amount of time.
It was also reported back in May that Sunvault and Edison have combined efforts in producing the world’s largest 10,000 Farad Graphene Supercapacitor that could power a Semi-Truck “while only being the size of a paperback novel.”
