Nissan’s Solid-State Battery Venture and the Pursuit of Cost Reduction

Nissan is making significant strides in the pursuit of cost reduction and enhanced performance in electric vehicles (EVs). The Japanese automaker recently announced plans to employ 100 workers per shift, starting in April 2028, with the goal of increasing solid-state battery production to 100 megawatt-hours per year. While the initial capacity and production ramp-up details were not provided in the press release, it is clear that Nissan is committed to tapping into the potential of solid-state battery technology.

Solid-state batteries have garnered attention for their potential to offer approximately twice the energy density of conventional lithium-ion batteries, along with shorter charging times and reduced costs. Nissan aims to leverage these advantages across a range of vehicle segments, including pickups, to enhance the competitiveness of their EV offerings. Although specific details regarding the application of solid-state batteries were not disclosed, Nissan has been actively working on solid electrolyte cell technology for years.

The pilot plant in Yokohama, currently under construction, plays a pivotal role in Nissan’s battery production plans. Scheduled for operation in 2029, this facility will pave the way for series production of solid-state batteries. Nissan has also revealed its intention to improve cell technology and production processes for solid-state batteries by 2025. While specific technical data has not been provided, Nissan remains focused on refining and optimizing the key components required for the successful integration of solid-state batteries into their future EV line-up.

Furthermore, in their quest for cost reduction, Nissan is exploring the use of the gigacasting process in the production of EVs. By employing a large die-casting machine weighing over 6,000 tonnes at the Tochigi plant, Nissan aims to manufacture larger cast parts in a single piece. This approach is expected to reduce manufacturing costs by ten percent and component weight by 20 percent compared to current production methods that involve the assembly of multiple individual parts.

Nissan’s decision to adopt the gigacasting process aligns with a trend pioneered by Tesla and its factory suppliers. While the advantages of this approach, such as weight reduction, cost savings, and faster production, are apparent, there are potential drawbacks related to repairability. With a single casting, the process of replacing individual frame parts becomes more complex and expensive after an accident.

Nissan’s commitment to solid-state battery technology and the exploration of innovative production processes reflects their dedication to advancing the EV industry. By investing in these areas, Nissan aims to not only improve the performance and competitiveness of their electric vehicles but also contribute to the ongoing evolution of sustainable transportation.
