eCell™ porous 95% silicon- 5% carbon composite anode material offering battery makers a lower cost drop-in replacement for graphite that enables a 30-50% boost in energy capacity
About
Our Solution eCell™ is a porous silicon-carbon composite powder that offers battery makers a swell-tolerant drop-in replacement for graphite that will enable a 30-50% increase in overall battery energy capacity. Comprised of 95% Si and 5% C, eCell’s unique architecture features micron scale powder particles, with nano-sized pores and walls. The larger particle size offers attractive commodity priced source materials with better areal density, conduction, tap density, and anode loading than competing nano-scale competitors. And eCell’s simple patent-pending fabrication process appears to enjoy significant cost advantages when compared with nano-particle fabrication. In half-cell testing, eCell anodes have not experienced catastrophic failure in over 1000 cycles of testing and retain 80% energy capacity for nearly 600 cycles. eCell could be used as a drop-in replacement to graphite, offering manufacturers minimal changes in tooling and process and the ability to continue leveraging existing investments in manufacturing and production infrastructure.
Key Benefits
High energy replacement for traditional graphite anodes: Significant reduction in Li-ion battery volume and weight for like or better energy output: Low-cost commodity precursor materials support overall cost reductions in energy per unit of materials; Leverages existing battery manufacturing machinery and processes as drop-in replacement for low-energy graphite; Optimized for Electric Vehicles, industrial tools and consumer devices - agnostic as to battery format; Compatible with wide range of existing cathode and electrolyte formulations;
Applications
EVs: Broad application to electric vehicle market with higher energy capacity (increased power and range) and reductions in volume and weight. Tools & Devices: Longer service life for tools and devices. Residential/Industrial Energy Storage: baseline technology for high energy applications to capture renewable energy sources for time-shifting to periods of time when renewable resources are unavailable (night, lack of wind or hydro).
