en.Wedoany.com Reported - Honda has signed a joint research agreement with QuantumScape to advance the development of a solid-state battery technology platform.
Solid-state batteries are expected to improve electric vehicle performance in terms of charging speed, energy density, cost, and safety, but the technology still faces multiple technical and engineering challenges before it can be applied on a large commercial scale. This collaboration indicates that electric vehicles remain a key part of Honda's long-term strategy. Previously, Honda recorded its first annual loss in the company's history, partly due to investments related to its electric vehicle projects.
The joint project encompasses a multi-year plan focused on solid-state battery development and associated manufacturing processes. Atsushi Ogawa, Chief Operating Officer of Honda's R&D Center of Excellence, stated that QuantumScape's technology demonstrated "compelling and unique advantages" during the evaluation process, and the company sees potential for the technology to add value in numerous applications, including automotive. This cooperation agreement is based on a successful technical evaluation previously completed by Honda, which included in-depth hands-on research on QuantumScape's solid-state technology platform and competitive benchmarking against a series of standard technical tests.
Headquartered in California, QuantumScape is a developer of solid-state lithium-metal batteries, characterized by its anode-free architecture and proprietary solid-state ceramic separator. Solid-state lithium-metal batteries replace the liquid electrolyte and polymer separator found in conventional batteries with a solid-state separator and allow for the use of a higher energy density lithium-metal anode instead of standard carbon or silicon anodes. According to the company, this technology has the potential to improve battery energy density, shorten charging times, extend lifespan, enhance safety, and reduce manufacturing costs compared to traditional lithium-ion batteries.
Dr. Siva Sivaram, CEO and President of QuantumScape, stated that Honda, renowned for its exceptional engineering and product quality in the automotive and other sectors, conducted one of the "most rigorous evaluations" of QuantumScape's technology, and the agreement reflects growing market confidence in the company's solid-state lithium-metal batteries. Earlier this year, Honda also entered into a joint agreement with Sumitomo Metal Mining to co-manufacture all-solid-state batteries.
Several automakers, including Honda, are scaling back or canceling some of their electric vehicle plans. For example, Honda canceled the Honda 0 Saloon and AFEELA models developed in its joint venture with Sony. Honda reported an operating loss of 414.3 billion yen (approximately $2.6 billion) for the fiscal year 2025/26, citing electric vehicle-related losses and tariff impacts as key issues for its business. For the fiscal year 2025/2026, Honda's total electric vehicle-related losses amounted to 1.578 trillion yen (approximately $9.95 billion). The partnership with QuantumScape indicates that the Japanese automaker has not completely abandoned its electrification direction, even though it has abandoned its previous goal of becoming a pure electric vehicle company by 2040 and has updated its strategy to achieve carbon neutrality by 2050.
