Pure silicon anode technology, boosting lithium-ion battery capacity by 70% for the world’s highest energy density of 1350 Wh/L, making batteries smaller and more powerful. The multi-patented silicon morphology provides a unique position to disrupt the industry with a tenfold capacity to story lithium ions and lightning-fast charging. The patented PECVD production method is scalable and low-cost, decreasing production complexity and CO2 emissions by 85%, as compared to conventional anode production using graphite, a scarce and polluting material. Thereby breaking energy barriers for a myriad of sustainable electrification of society and enabling an energy transition using clean and abundant materials.
