Prototype 21700 lithium-ion cells incorporating silicon anodes will be made available for third party analysis after battery developer Bisolar completed initial testing of its second batch of commercial-grade cells.
The California, US, company is making the prototypes available to potential development partners for their in-house qualification and analysis, which will be used to develop its battery technology for electric vehicles.
In this phase of prototype development, BioSolar prepared two different types of commercial grade 21700 cells intended for power tool application.
The first used silicon alloy anode material comprised of silicon micro-particles (Si-MP). The second used pure silicon anode material comprised of Si nano-particles (Si-NP).
The company reported that initial test results for the power and energy capabilities of both types of prototype cells indicated “substantial improvement in power and energy capabilities”.
Dr. David Lee, chief executive officer of BioSolar, said: “The next phase of testing and analysis feedback is especially helpful, as it will likely portray actual market response, meaning we view this as a test of our commercial viability.
“That said, we understand this is a process that will continue to require fine tuning, of which we will continue disclosing in corporate updates to the public, potential partners and shareholders.”
