Honda targets 50% weight reduction in solid-state batteries for mainstream electric vehicles.

Home > Industry Analysis > Content

【Summary】Honda plans to reduce the weight of solid-state battery packs in its mass market EVs by 50%, potentially doubling the range of vehicles on its existing EV platform or allowing for smaller packs in new models. The company is on track to start pilot solid-state battery production and sees solid-state batteries as a way to achieve better access to charging rather than relying solely on increased battery size.

Honda targets 50% weight reduction in solid-state batteries for mainstream electric vehicles.

Honda is making progress in its pilot solid-state battery production and has outlined its plans for utilizing the advantages of this technology. One possibility is that it could double the range of vehicles built on its existing EV platform. Alternatively, Honda may opt for smaller battery packs in new mass market EVs.

Last year, Honda announced its intention to invest approximately 43 billion yen in building a demonstration line for the production of all-solid-state batteries. The company aims to start demonstration production by Spring 2024 as part of its electrification strategy, which involves a $40 billion portfolio.

Honda executives recently confirmed their plans for EVs powered by solid-state electrolyte cells during an interview. Unlike some US automakers who have taken a "bigger is better" approach to EVs, Honda believes that the opposite approach is more optimal.

The key to addressing range anxiety, according to Honda, is not simply increasing battery capacity, but improving access to charging infrastructure. Honda has already announced that it is in the proof-of-concept stage with solid-state technology, which has the potential to reduce weight and increase vehicle range.

Internal testing conducted by Honda indicates that solid-state battery technology can increase energy density, resulting in a 50% reduction in battery pack weight. This means that the same energy can be stored in a smaller, lighter battery. Shinji Aoyama, Honda's EV strategy head, explains that the energy density would be doubled, allowing for double the energy volume in the same car.

When it comes to utilizing the benefits of solid-state battery lightness, Honda plans to introduce double the energy volume into its existing EV platform once all-solid-state batteries are implemented. This will also apply to planned models like the Acura ZDX.

Looking ahead, Honda recognizes the future potential of smaller and more affordable mass market electric vehicles. Shinji Aoyama states that when Honda develops new products, they will apply a smaller battery case, taking advantage of the design flexibility offered by solid-state batteries.

Honda is preparing for the era of smaller and cheaper electric vehicles, similar to Tesla's upcoming Model 2. The company is actively exploring the possibilities enabled by solid-state battery technology.
