en.Wedoany.com Reported - Honda has partnered with US solid-state battery startup QuantumScape to jointly develop solid-state batteries for electric vehicles and other applications. After a long period of quietly evaluating QuantumScape's technology, Honda decided to pursue public collaboration and advance research and development to the next stage. QuantumScape revealed that the "joint research agreement" signed by both parties includes a multi-year plan focused on developing solid-state batteries and associated manufacturing processes.
Honda recently halted several next-generation EV models but views electrification as a long-term direction. Solid-state batteries replace traditional liquid electrolytes with solid electrolytes, theoretically offering greater safety, faster charging, and higher energy density than the commonly used lithium-ion batteries, though commercialization remains challenging.
Earlier this year, QuantumScape made progress by starting trial production of lithium-metal cells on a fully automated production line in San Jose. The company plans to license its intellectual property and manufacturing processes to automakers rather than becoming a traditional battery supplier. Volkswagen Group is also a partner and investor in QuantumScape.
The automotive industry has been focused on solid-state batteries for years. Toyota has promoted its investments since 2010, General Motors tests solid-state cells in its battery lab, and Honda has also advanced its solid-state battery R&D, making bold predictions. In 2024, Honda stated that solid-state batteries could reduce volume by 50%, weight by 35%, and manufacturing costs by 25% compared to existing cells, with a single-charge range of approximately 1,000 kilometers. Honda also expects that by 2040, EVs equipped with solid-state batteries could achieve a single-charge range of around 1,250 kilometers.
