Ampcera says its Patent-Pending Technology for Solid-State Batteries can Enable Ultra-Fast Charging

Ampcera Inc., has announced a patent-pending technology for all-solid-state batteries, enabling ultra-fast charging in electric vehicles.

Ampcera recently published a worldwide patent application titled "Internally Heatable Battery, Internally Heatable Battery System, Internally Heatable Battery Method, and Electric Vehicle Comprising the Same". The company said the solution is a low cost, energy-efficient internal heating battery architecture that directly targets the solid electrolyte separator, the key component in solid-state batteries. This novel technology from Ampcera enables solid-state batteries to deliver superior performance, including starting and operating in cold weather, charging ultra-fast and safely, and increasing power rate and energy efficiency in next-generation electric vehicles.

The novel solid-state battery design and the ionic conductivity of the solid-state electrolyte are increased by more than 10 times when needed while keeping the battery operating continuously at ambient temperature. Moreover, interface resistance between the solid electrolyte and positive and negative electrodes are significantly diminished. The combination of enhanced conductivity and reduced interface resistance enables solid-state batteries to be rapidly charged in a few minutes.

"Ampcera's technology portfolio includes high-performance solid-state electrolytes, scalable manufacturing processes, and innovative solid-state battery designs. We are very excited to announce this new technology for ultra-fast charging of solid-state batteries. The next step is to incorporate this technology into all-solid-state battery cells for further performance testing by Ampcera and our automotive OEM partners,"

said Dr. Hui Du, co-founder and CTO of Ampcera.

By 2025, Ampcera's solid-state electrolyte and battery technologies are projected to reach less than 10-minute ultra-fast charge and gravimetric and volumetric energy densities of 450 Wh/kg and 1400 Wh/L, respectively. The company says that by using scaled manufacturing processes for mass production, can achieve a competitive battery cost of less than $75 per kWhr hour.
