BioSolar, a developer of breakthrough energy storage technology and materials, today announced that the Company has executed a joint development agreement with Top Battery Co., Ltd. ("Top Battery"), a leading manufacturer of advanced lithium-ion battery solutions, based in the Republic of Korea.

Santa Clarita, CA - June 6, 2017 - BioSolar, Inc. (OTCQB:BSRC)("BioSolar" or the "Company"), a developer of breakthrough energy storage technology and materials, today announced that the Company has executed a joint development agreement with Top Battery Co., Ltd. ("Top Battery"), a leading manufacturer of advanced lithium-ion battery solutions, based in the Republic of Korea.

This agreement follows the Companys previous announcement that it had successfully completed the laboratory phase of its silicon alloy nanocomposite anode material development with data suggesting its technology can achieve significantly higher capacity with lowered costs. The Company has also recently commenced the engineering phase that focuses on designing and testing the electrodes based on the Companys anode material, as well as full cell design and evaluation with commercially available high capacity cathodes.

BioSolar, with its proprietary technology relating to silicon alloy nanocomposite anode material for lithium ion batteries, believes Top Battery is a natural fit as a developmental partner. Top Battery possesses experience in incorporating technologies such as BioSolars anode material, and in designing and manufacturing lithium-ion electrodes, cells and battery systems for customers. BioSolar and Top Battery have agreed to ongoing, collaborative efforts to assess, develop, manufacture, and/or market high power high energy lithium ion batteries integrating BioSolar technology and Top Battery technology.

"We are excited to partner with BioSolar, a company whose technology represents tremendous upside in the field of lithium-ion battery manufacturing," said Dr. Whan Jin Roh, CEO of Top Battery. "We are hopeful that BioSolars focus on silicon alloy nanocomposite anode material development will yield results that ultimately reduce costs and improve efficiencies, a series of objectives that would immediately be of interest to the global market."

"We are pleased to have Top Battery as a development partner, given their experience in incorporating innovative and developing technologies such as our own, and bringing them to market," said Dr. David Lee, CEO of BioSolar. "We are confident that this partnership and its subsequent results will continue to demonstrate not only higher performance but also better price points, strengthening BioSolars commercial viability and market potential."

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.
