BioSolar Announces Breakthrough Test Results from its Silicon Anode Technology for Lithium-ion Batteries

Company’s proprietary silicon anode additive technology is the key to reduce the cost and significantly improve performance of next generation lithium ion batteries

Santa Clarita, CA – February 13, 2018 –BioSolar, Inc. (OTCQB:BSRC) (“BioSolar” or the “Company”), a developer of breakthrough energy storage technology and materials, today announced that it has achieved a significant performance milestone in silicon micro-particle (SiMP) anodes enhanced by its innovative silicon (Si) anode additive technology.

BioSolar recently applied its proprietary additive to SiMP material through a facile commercially available process and performed extensive charge/discharge testing that demonstrated almost 100% capacity retention at 600mAh/g (with current density of 1mA/cm2) over 300 cycles. To put this in perspective, the industry’s current performance target for initial Si anode testing is 600mAh/g and 80% retention following 300 cycles. One cycle consists of a complete charge and discharge function.

“This is a very significant demonstration of capability, one we believe will foster collaboration with potential customers as well as silicon micro-particle or bulky powder suppliers,” said Dr. David Lee, Chief Executive Officer of BioSolar. “The outcome of this achievement using our proprietary technology will be extremely beneficial to battery manufacturers, as well as all electric device companies that continue to seek high energy and high power batteries, all at low costs. We believe the high performance and low-cost potential of this technology will result in increased adoption of various consumer applications, such as electric vehicles.”

The industry standard for Si anodes currently uses Si nano-particles, but the difficulty of manufacturing raw Si nano-particle materials remains a costly challenge. By contrast, Si micro-particles are easier to manufacture at a significantly lower cost. Unfortunately, anodes made from Si micro-particles are more prone to damage during battery charging and discharging due to volume expansion, thus not yet commercially viable. BioSolar’s innovative additive technology is designed to solve this problem.

About BioSolar, Inc.

BioSolar is developing a breakthrough technology to increase the storage capacity, lower the cost and extend the life of lithium-ion batteries. A battery contains two major parts, a cathode and an anode, that function together as the positive and negative sides. BioSolar initially focused its development effort on high capacity cathode materials since most of today's Li-ion batteries are "cathode limited." With the goal of creating the company's next generation super battery technology, BioSolar is currently investigating high capacity anode materials recognizing the fact that the overall battery capacity is determined by combination of both cathode and anode. By integrating BioSolar's high capacity cathode or anode, battery manufacturers will be able to create a super lithium-ion battery that can double the range of a Tesla, power an iPhone for two days straight, or store daytime solar energy for nighttime use. Founded with the vision of developing breakthrough energy technologies, BioSolar's previous successes include the world's first UL approved bio-based back sheet for use in solar panels.
