Volt Carbon Technologies and Charge CCCV (C4V) have announced successful test results from Volt’s lithium metal electrolyte paired with C4V’s advanced biomineralized lithium mixed metals phosphate (BMLMP) cathodes, and Volt’s dry separated graphite paired with C4V’s Green Anode technology.

The combination of Volt’s lithium metal electrolyte and C4V’s BMLMP cathodes achieved enhanced energy density that outperformed conventional lithium iron phosphate (LFP) technologies. Coin cells demonstrated stable capacity retention beyond 650 cycles with minimal capacity fade.

The results highlight the potential of Volt’s electrolyte to optimize the performance of C4V’s BMLMP cathodes for high-energy-density applications.

C4V’s SP Series technology is expected to deliver close to 300 Wh/kg with BMLMP cathode without cobalt or nickel.

Volt processed graphitic rock from Green Battery Minerals’ Berkwood deposit using its dry separation technology at its Scarborough, Ontario facility. The refined material was then integrated into C4V’s Green Anode process to produce battery-grade anode electrodes.

Performance testing demonstrated a specific discharge capacity of 363.7 mAh/g (0.01 V–1.0 V at 0.05 C), with a first-cycle efficiency (FCE) of 93.6%.

Volt and C4V are advancing to pouch cell development with the goal of scaling their technologies for larger-format batteries. The next steps include transitioning from coin cell testing to pouch cell testing, optimizing production processes to ensure scalability, and refining the integration of these technologies for use in EVs and other applications requiring high energy density and reliability.

“We continue to be pleased with Volt Carbon’s progress through our Supply Chain Qualification process and the results bode well for our collaboration. C4V’s work with Volt Carbon supports our vision to bring transcendent lithium-ion battery technologies that are scalable to the commercial market,” said Clifford Olin, CBO of Charge CCCV.
