Ampcera Inc., an innovator in solid electrolyte technologies for advanced electric vehicle batteries, announced its patent-pending technology for all-solid-state batteries, which according to a company press release, enables ultra-fast charging in electric vehicles.
The recently published worldwide patent application titled Internally Heatable Battery, Internally Heatable Battery System, Internally Heatable Battery Method, and Electric Vehicle Comprising the Same deals with a “low-cost, energy efficient internal heating battery architecture that directly targets the solid electrolyte separator, the key component in solid-state batteries,” according to the press release. Ampcera states that the technology 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.
“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 in the press release.
The press release stated that with its solid-state battery design, the ionic conductivity of the solid-state electrolyte is increased by more than 10 times when needed while keeping the battery operating continuously at ambient temperature. The company also claims that the interface resistance between the solid electrolyte and positive and negative electrodes is significantly diminished. “The combination of enhanced conductivity and reduced interface resistance enables solid-state batteries to be rapidly charged in a few minutes,” according to the press release.
