The program between QuantumScape (QS) and Honda R&D involves a multi-year plan focused on the development of solid-state batteries and related manufacturing processes. The agreement follows the signing of a technology evaluation agreement between Honda and QS, which included an in-depth, hands-on technical evaluation of QS’s solid-state technology platform as well as a competitive analysis based on various standardized technical tests.

The Potential of QS Technology

“QS technology demonstrated compelling and unique advantages during our evaluation,” says Atsushi Ogawa, Chief Operating Officer of the Research Center of Excellence at Honda R&D, adding: “We see potential for QS technology to create added value in a range of application areas, including the automotive industry, and look forward to moving into the next phase of our partnership.”

With its solid-state lithium-metal battery technology, QuantumScape aims to enable higher energy density, faster charging, and improved safety to contribute to decarbonization. The company is therefore pleased to have secured Honda as a partner, as Dr. Siva Sivaram, CEO and President of QS, emphasizes: “Honda is a world-leading automaker, renowned globally for its technical excellence and product quality in the automotive sector as well as in other application areas, and its evaluation represents one of the most rigorous assessments of our technology to date. This agreement reflects the growing confidence in QS’s solid-state lithium-metal batteries, which enable safer energy storage with higher energy density.” (se)
