The Finnish cleantech startup uses proprietary water-based electrochemistry and patent-pending ECR technology to create rechargeable batteries that combine energy storage mechanisms from batteries and supercapacitors, providing fast-storage batteries with a minimal cost per charge, lowest in class greenhouse gas emissions, maximum safety, and ease of recycling. Geyser Batteries' supply chain presents a stark contrast to the challenges of the traditional battery industry as it is free of Nickel, Cobalt, and other traditional electrode materials.
