The Japanese manufacturer Honda is betting on solid-state batteries to revolutionize electric vehicles before 2030.
This technology could offer record-breaking ranges, but its industrialization remains a major challenge. Honda is accelerating its efforts in the field of solid-state batteries, a technology that could disrupt the electric vehicle industry.
The manufacturer plans to market its first models equipped with these batteries before 2030, promising an impressive range of 1,000 kilometers per charge. By 2040, this range could reach 1,250 kilometers thanks to further advancements.
Solid-state batteries offer several advantages: they are 50% smaller, 35% lighter, and 25% less costly to produce than current lithium-ion batteries. Additionally, they provide higher energy density and faster charging times. They are also safer due to the absence of flammable liquid electrolytes.
Despite their potential, solid-state batteries are not yet ready for mass production. Current prototypes are 100 times too small to be integrated into vehicles. Honda has therefore created a pilot line to address size issues and develop innovative manufacturing processes. For example, roll pressing to form ultra-thin electrolyte layers can be cited.
Other technical challenges remain. Notably, the fragility of ceramic separators and the rigorous control of humidity in factories, which requires costly investments. However, Honda remains confident. Keiji Otsu, president of Honda R&D Co, describes this innovation as a “game changer” for the electric vehicle industry.
With this advancement, Honda hopes to catch up with its competitors and play a key role in the era of electric vehicles. But the manufacturer also aims to meet the growing consumer demand for durable and high-performance solutions.
