BSRC: Can double the range of a Tesla, page-12

This is from a BioSolar PR from Oct 2018.
"Representatives of BioSolar and the Company’s technology partners, recently visited Top Battery, another technology development partner, in South Korea. During the trip, BioSolar also met with a number of technology companies including a potential technology development partner with extensive knowledge and capability in Si anode material processing. As a result of these meetings, the team is in the process of forming a mutually beneficial alliance with the aforementioned partners in South Korea to integrate BioSolar’s solid additives into Ferroglobe’s Si raw materials to produce Si anode materials incorporating BioSolar’s additive technology. BioSolar has continued its collaboration with Top Battery to design and build commercial grade prototype batteries to demonstrate the benefits of the Company’s own Si additive technology for next generation Li-ion batteries. Furthermore, BioSolar intends to establish additional development partnerships to ensure successful preparation of the Company’s Si anode material to be incorporated into commercial grade proof of concept Li-ion full cell prototypebatteries. “Our team’s recent trip to South Korea was very productive in that it advanced our established relationships with Ferroglobe and Top Battery, but also established new ones with potential long-term partners,” said Dr. David Lee, Chief Executive Officer of BioSolar. “Ultimately, our goal for success will be enabled by two key initiatives: one on the technology development side, and the second being our ability to form meaningful, mutually beneficial relationships with the right partners. We believe both objectives are each on their respective track for success, and look forward to sharing details of these relationships as they mature.”

Anteo revealed this in Mar 2019 . "August 2018 – Materials transfer agreement with NorthAsia battery materials global supplier." Not much to go on but the timing and product align.
