BioSolar Completes Successful Lab Phase of Its High Capacity, Low Cost Anode Material Technology


BioSolar, Inc., a developer of breakthrough energy storage technology and materials, recently announced that the Company has successfully completed the laboratory phase of its silicon alloy anode material technology development. With data that suggests its technology can achieve significantly higher capacity with lower costs, the Company will now commence the process of identifying potential strategic partners for commercial development of its proprietary battery technology. BioSolar’s laboratory test results suggest that lithium-ion batteries incorporating BioSolar’s silicon (Si) alloy anode can achieve significantly higher capacity than the conventional graphite anode. Further the Company’s anode costs less when compared to other silicon anodes currently under development.

CEO Dr. David Lee and BioSolar joint research team members recently attended the 34th Annual International Battery Seminar & Exhibit in Fort Lauderdale, Florida to share and discuss the latest development on BioSolar’s advanced silicon anode material technology with a select group of potential partners and customers. The technology discussion included a half-cell demonstration which highlighted a performance comparison between BioSolar’s Si alloy anode and a benchmark Si-based anode.

The half-cell demonstration was focused on an apples-to-apples comparison of BioSolar’s Si alloy anode materials to a benchmark Si anode material. BioSolar’s Si alloy anode was shown to have specific capacity of 1,235mAh/g with 95.3% of capacity retention, as compared to the best-known competitor’s 1,181mAh/g specific capacity with 91.0% capacity retention. Further, BioSolar’s Si alloy anode demonstrated over 99.8% of cycle (charge-discharge) efficiency during 100 cycles of operation with lithium metal half-cell.

At the full cell configuration, capacity is limited by cathode capabilities which result in much lower battery capacity than that of the half-cell configuration. A full cell battery incorporating BioSolar’s Si Alloy anode and the highest capacity cathode commercially available (lithium nickel cobalt aluminum oxide cathode with specific capacity of 180mAh/g at 4.3V), exhibited 99.6% of capacity retention over 50 cycles – a figure that projects a very high capacity retention at and beyond 200 cycles. BioSolar’s initial target for its Si alloy anode development is 620mAh/g at the full cell configuration, but further enhancement will allow the Company to reach 1000mAh/g in the near future.

The Company’s next step is to identify potential partners for BioSolar’s Si alloy anode material technology, and jointly consider the wide-ranging applications for breakthrough lithium-ion battery technology. BioSolar’s attendance at this event was a crucial step towards establishing relationships with potential partners as the Company works towards commercialization of its technology. The Company’s Si alloy anode has already been shown to have over 1000mAh/cm3 of volumetric capacity density, which will be suitable for high energy density product application including portable smart devices, drones, and electric vehicles.

“Completing laboratory phase development is a milestone achievement for the Company, one that provides us the platform and credibility to begin speaking with potential manufacturing and development partners,” said David Lee. “The feedback received at the Annual International Battery Seminar & Exhibit only further reinforces the potential partnerships, and wide-ranging application, that we feel our anode technology is suitable for. We are confident that our approach will continue to demonstrate not only higher performance but also better price points.”
