Honda targets 50% reduction in weight of solid-state battery packs for mainstream electric vehicles

Honda is making progress in its pilot solid-state battery production and has revealed its plans to leverage the advantages of these batteries. One possibility is to double the range of vehicles built on its existing EV platform. Another option is to use smaller packs in new mass market EVs.

Last year, Honda announced its intention to invest approximately 43 billion yen to build a demonstration line for the production of all-solid-state batteries. The goal is to start demonstration production in Spring 2024 as part of Honda's US$40 billion portfolio electrification strategy.

In a recent interview, Honda executives confirmed their plans for EVs powered by solid-state electrolyte cells. Unlike some US automakers, Honda believes that a different approach is optimal, rather than simply applying the "bigger is better" ICE vehicle approach to EVs.

Honda recognizes that the solution to range anxiety is not solely dependent on larger batteries, but also improved access to charging infrastructure. With solid-state battery technology, weight reduction and increased range are potential benefits. Honda has already announced that it is in the proof-of-concept stage with solid-state technology.

According to Honda's internal testing, solid-state batteries can increase energy density, resulting in a 50% reduction in the weight of the battery pack. This means that the same energy can be stored in a smaller and lighter package. 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 advantages of solid-state battery lightness, Honda plans to incorporate double the energy volume into its existing EV platform once solid-state technology is introduced. This could also apply to planned models like the Acura ZDX.

Honda is also preparing for the future of mass market electric vehicles, which are expected to be smaller and more affordable than current models. Shinji Aoyama mentions that once Honda develops something new, they will apply a smaller battery case for that product, taking advantage of the design flexibility that solid-state batteries offer.

In conclusion, Honda's pilot solid-state battery production is progressing as planned, and the company has ambitious goals to enhance the range and design flexibility of its EVs.
