EnerMat Technologies, based in Clifton Park, New York, is a fast-paced battery startup developing graphene and silicon based electrodes for advanced lithium-ion batteries. The overarching goal of the company is to positively impact the world’s greenhouse gas emission problem and accelerate the electrification of the transportation system. An important challenge that remains to be solved for this to be achieved is the development of scalable, cost-effective approaches to designing a better battery. With a strong nanotechnology and material science background, the founders aim is to change battery manufacturing economics through innovations on the nanoscale.
Initially, the company has been working with consumer and wearable electronics manufacturers, as well as UAV and drone developers, because these nascent markets are still evolving and better batteries would dramatically impact the device’s utility to the user. The innovation in EnerMat Tech’s technology lies in its novel electrode materials that facilitate high energy densities, which lead to longer operational time on a single charge.
EnerMat-Tech's industrially compatible, roll-to-roll synthesis process is highly scalable, and has the advantage of not disrupting existing manufacturing plant lines. The specially designed nanostructured electrodes are thus produced efficiently and economically.
They provide a higher storage capacity for lithium ions, and can be tuned to deliver ~600- 900 mAh/g based on their design. This is ~2 to 3 times higher than conventional graphitic anodes. The resulting energy density of EnerMat Tech’s Li-ion batteries is ~300-450 Watt-hour/kg, far surpassing the energy densities of state-of-the-art lithium ion batteries that generally range from 200-250 Wh/kg.
EnerMat-Tech has successfully scaled its graphene technology from coin cells up to lab prototypes of larger-format 20-100 mAmp-hour pouch cell configurations. With funding from NYSERDA, EnerMat-Tech is currently working on manufacturing minimum viable products (MVPs) of pouch cells on a semi-automated line, ranging from 100-500 mAmp-hours for proof-of-concept testing with partners.
Eklavya Singh, CEO and co-founder of EnerMat-Tech commented: “NY-BEST's Bench-to-Prototype award has been instrumental in our company’s growth, as they provided us with funding and manufacturing resources while also connecting us to a vast network of experts in the energy space. We have used this opportunity to significantly de-risk our technology in the first few months, and are looking forward to engaging customers as we move forward with the prototyping phase of this award."
EnerMat-Tech was founded by recent mechanical engineering graduates, Dr. Rahul Mukherjee and Dr. Eklavya Singh, from Rensselaer Polytechnic Institute, who developed the electrode technology during their tenure there and have since licensed it for use in their company.
