Strong-state batteries aren’t just a few new know-how for Honda; they signify the very way forward for the corporate. The Japanese model goals to be one of many first globally to convey this product to market and provoke mass manufacturing. They’re making certain they’ll retain tight management over the event means of this core know-how by not outsourcing the analysis or manufacturing of SSBs, however relatively, preserving each a part of the method in-house. Honda’s technique for SSBs is a holistic one, the place it envisions mass-production strategies even from the early phases of improvement. Every thing, from optimum dimension to supplies and manufacturing strategies, is taken into account throughout the improvement interval. The higher its mastery of the event course of, the higher the top product will probably be. In-house SSBs will probably be important for Honda to develop higher and extra inexpensive EV merchandise within the close to future.
Honda’s Improvement Timeline
Honda has acknowledged its objective is to introduce SSBs to manufacturing fashions by the second half of the 2020s. It’s reasonable to anticipate the implementation of Honda’s SSBs by 2028, which they contemplate the beginning of the “mid-term” of their battery improvement roadmap. By then, the model additionally plans to have established full-scale battery knowledge traceability, the applying of sustainable supplies, and the scaling up of its EV worth chain. These developments imply that electrical vary is ready to double within the second half of the 2020s from about 300 miles to 600 miles. Concurrently, SSBs will permit for a 50 p.c discount in dimension, a 35 p.c discount in weight, and a 25 p.c discount in price. If Honda can handle to attain this potential, it is going to comprehend it has secured a aggressive edge forward of different automakers in our future EV panorama.
Honda’s Method And Main Breakthroughs
The time period “gamechanger” is usually used too loosely in rising automotive know-how, however the development of solid-state batteries is a driving pressure not like every other within the trade. The easy truth is that this know-how could have an enormous influence on the effectivity and potential of EVs, and the earlier we get it, the higher for everybody.
How Honda Is Defining Themselves
Honda’s main focus with SSB improvement is designing the best high quality materials for the stable electrolyte, crucial structural part of SSBs. Honda has leveraged a particular single-particle energetic materials with a excessive cracking resistance and utilized it through roll-pressing to extend the density of the stable electrolyte. Merely put, the higher the contact materials, the higher the vitality density.
Many of those processes, like roll-pressing, have been tailored from standard lithium-ion battery manufacturing. Nonetheless, what usually requires a four-step course of for electrolyte filling in lithium-ion batteries might be achieved in a single step with solid-state manufacturing. This makes the roll-pressing technique much more efficient for SSBs because it affords the next manufacturing productiveness that’s as much as eight occasions greater than lithium-ion-based practices.
Honda’s Expectations And Validation Course of
When Honda talks about SSBs, its expectations for the know-how are clear: excessive vitality density, secure chemical reactions, and excessive ionic conductivity. The upper the vitality density, the longer the vary, the upper the ability output, and the lighter a battery pack might be. With extra secure chemical reactions, SSBs can function at wider and considerably greater temperatures. Elevated warmth resistance implies that costly and complicated liquid cooling methods might be simplified or outright eradicated. The advantages lead to longer vary, decrease price, higher packaging, higher efficiency, and shorter charging time.
Whereas SSBs sound like the proper resolution to all our present EV woes, validating the mass-production viability of this know-how is an ongoing course of. Honda is tackling the best option to streamline the SSB manufacturing course of in a method that can optimize high quality, price, and stability. Because it stands, solely one of many ten key manufacturing processes is able to working at full capability in a mass-production setting.

Honda’s Present Plan And The Relaxation Of The Business
Again in 2024, Honda accomplished development of its first SSB manufacturing advanced within the metropolis of Sakura, situated in Tochigi Prefecture, Japan. This development is funded partially by the roughly $275 million that Honda has invested in SSBs in 5 years, from 2023 to 2027. This landmark facility is Honda’s main technique of validating the fabric specification and manufacturing processes of SSBs earlier than scaling. This demonstration facility turned operational in January 2025 and has already displayed its usefulness in decreasing eventual mass manufacturing prices.
Honda’s Present SSB Street Map
Honda’s SSB improvement began in a lab again in 2020, and now, six years later, prototype cells are being produced on the Sakura facility for mass-adoption verification. By the point we see these superior batteries in a new Honda mannequin, it is going to possible be 2028. In response to Honda, it takes a minimal of two to 3 years from the planning part to construct a mass manufacturing plant of the size meant. But, the 295,000-square-foot Sakura facility is accelerating the method as quick as potential.
It has been constructed to imitate the precise format and methodology anticipated for use in mass-production services. This may permit for minimizing lead occasions and eliminating pointless work processes after precise specs have been decided. Identical to on the Sakura facility, battery cell and module manufacturing will probably be carried out with a three-building design, the place Constructing C1 will deal with the optimistic electrode and insulating layer coating, together with cell meeting. Then, Constructing C2 will deal with the unfavorable electrode formation, whereas Constructing C3 is the place the ultimate formation and module meeting happen.
Honda’s Relationship With The Relaxation Of The Business
Though Honda has chosen to develop their solid-state batteries in-house, this doesn’t imply it doesn’t have strategic partnerships with different manufacturers within the trade. Presently, Honda collaborates with LG for the manufacturing of lithium-ion batteries. Nonetheless, by 2028, Honda seems to take management and vertically combine its EV worth chain as the first battery provider for all of its three way partnership companions. Whereas Honda’s dedication and funding in SSBs is among the many highest of any automaker, it’s not alone within the race to attain the primary mass-production SSB-powered automobiles.
Toyota, Honda’s perennial rival, has its timeline for manufacturing functions of its personal proprietary SSBs set round 2028. Nissan can be within the combine, and so they, too, purpose to launch an EV by 2028 with SSBs, all developed totally in-house. With lithium-ion know-how, most automakers supply battery cells from the identical small group of recognized suppliers, like LG. Nonetheless, automakers are banking on their very own bespoke applied sciences to be their X issue within the battle of SSBs. If Honda can validate the economics of dependable and cost-effective SSBs earlier than anyone else, they are going to have a definite edge over the remainder of the competitors. SSBs aren’t the one resolution for a carbon-neutral future, however they’re among the many applied sciences that will decide the subsequent decade or two of automotive engineering.
