Modern consumer electronics devices such as smartphones, tablets and notebooks use rechargeable lithium ion batteries as their energy source. However, the duration of use, recharging speed, processor power and functionality of these devices are limited by constraints on battery weight and volume as well as the energy capacity of current battery technologies. In many cases, current batteries can’t meet the energy and power density required by many applications.

This E-Team is developing SiNode, an advanced anode technology that increases the energy density (5-7 times) and reduces the charging time of lithium-ion batteries up to a factor of 10. SiNode’s technology uses a composite of silicon nano-particles within a patent-pending graphene scaffolding system. These anodes are fabricated using a solution-based manufacturing process that is scalable and easily integrated into existing manufacturing processes.
