Strengthening core businesses based on powder and materials technologies

「In addition to expanding applications and customers for battery products, we are advancing the establishment of technology for mass production of nickel-zinc batteries.」

「For the nickel-zinc battery, the Company established the Nickel-Zinc Battery Business Promotion Office in April 2025 and is developing cells and assembled battery packs with the aim of starting mass production during fiscal 2027. The product has so far been introduced to more than 50 companies, which have evaluated its benefits as a replacement for lead-acid batteries, and some customers are conducting demonstration tests.」

「In the battery business, we developed a high-capacity, high-output cylindrical lithium manganese dioxide primary battery; nickel-zinc batteries were adopted for a demonstration experiment involving grid-free solar carports; we developed a high-capacity AB2-type hydrogen-absorbing alloy for hydrogen storage tanks using nickel-metal hydride batteries; and, in addition to a high-energy-density model, we developed a model compatible with constant-voltage charging for SMD miniature all-solid-state batteries.」

「In the battery business, the Company developed high-capacity, high-output cylindrical manganese dioxide lithium primary batteries, adopted nickel-zinc batteries for a demonstration experiment involving grid-free solar carports, and developed high-capacity AB2-type hydrogen-absorbing alloys for hydrogen-storage tanks,」

「For the nickel-zinc battery, the Company introduced the product to several dozen companies during the fiscal year. Customers, particularly those using the batteries for power backup and mobility applications, recognised its benefits as a replacement for their existing lead-acid batteries. The Company shipped samples of assembled battery packs and is currently receiving evaluations using actual equipment. In April 2025, it newly established the Nickel-Zinc Battery Business Promotion Office and is accelerating development toward mass production, aiming to balance battery characteristics, production quality and cost.」

「For the nickel-zinc battery, the Company steadily advanced performance improvements by presenting the results of materials development at academic conferences and highlighting improvements in cycle life. Going forward, it will expand the destinations for sample shipments with the aim of switching from lead-acid batteries currently used for motive power and backup power, and will strengthen its efforts toward mass production.」

「To secure a stable supply of the hydrogen-absorbing alloy that is a key raw material for nickel-metal hydride batteries and to grow into a group with globally recognised capabilities in hydrogen storage in preparation for the coming hydrogen society, the Company decided to acquire an equity interest in 包頭三徳電池材料有限公司, which produces battery materials and rare-earth alloys.」

「The nickel-zinc battery, whose development the Company is advancing as a new battery, began sample shipments. For the hydrogen/air rechargeable battery, the Company conducted experiments assuming solar charging and held discussions with partners.」

「The nickel-zinc rechargeable battery is being prepared for sample shipments and mass production. For the hydrogen/air rechargeable battery, the Company conducted demonstration simulation tests as a stationary power source under an environmental commissioned project and is working to further reduce costs and improve performance.」

「The Company also began mass shipments of nickel-metal hydride batteries for the automotive accessories market, with improved discharge performance at low temperatures, and began selling high-capacity cylindrical manganese dioxide lithium primary batteries for smart meters and security equipment, offering low self-discharge and long-term storage, as well as nickel-metal hydride battery systems for the transportation infrastructure market. It also exhibited at trade shows and worked to expand the business.」

「To achieve the targets set out in the medium-term business plan “R1,” which began in April this year, the Company worked to transform the quality of its existing businesses, expand its product lineup in existing businesses, address demand related to healthcare and new lifestyles, and establish a mass-production framework. It began producing its SMD-compatible small all-solid-state battery at the Kosai Plant in Kosai, Shizuoka Prefecture.」

「The Company advanced the development of the mass-production line framework at its Kosai Plant in Kosai, Shizuoka Prefecture, in preparation for starting mass production of its SMD-compatible small all-solid-state battery during the third-quarter consolidated accounting period.」

「The Company began building a mass-production line at its Kosai Plant in Kosai, Shizuoka Prefecture, in preparation for starting mass production of its SMD-compatible small all-solid-state battery during the third-quarter consolidated accounting period.」

「As another next-generation battery, the Company is developing SoLiCellTM, an SMD-compatible small all-solid-state battery with a world-leading high voltage using a high-potential cathode material jointly developed with Fujitsu Laboratories Ltd., and is building the framework needed to begin mass production during the fiscal year.」

「During the fiscal year, to achieve this objective, the Company pursued structural reforms and initiatives to reorganise its business portfolio, including the transfer of part of the electronic components business and workforce optimisation based on the implementation of a career-transition support programme. It also worked on developing next-generation batteries, including SMD-compatible small all-solid-state batteries, hydrogen/air rechargeable batteries and nickel-zinc batteries, while expanding its industrial battery business within its existing operations.」

「In parallel with sample shipments of the high-capacity version of its SMD-compatible small all-solid-state battery, the Company pursued efforts toward commercialisation and launched the FUJITSU alkaline battery “Premium S” in September, featuring improved long-lasting performance, shelf life and leak resistance.」

「Alongside the start of sample shipments of high-capacity SMD-compatible small all-solid-state batteries, we advanced initiatives toward their commercialization and the commercialization of the FUJITSU alkaline dry-cell battery “Premium S,” scheduled for launch in September this year, with improved long-lasting performance, long-term storage performance and leak resistance.」

「We are developing electronic materials, electronic components, modules and synergy products with nickel-metal hydride and thin lithium batteries by fully utilizing the Group's key technologies, including powder and materials technology, process technology, CAE technology, circuit technology and high-density mounting technology.」

「We began providing samples of an ultra-small all-solid-state battery capable of high-voltage output, which has attracted market attention as a next-generation battery, and advanced initiatives toward its commercialization.」

「In addition to improving the characteristics of cathode materials for small all-solid-state batteries, we continued to advance the development of commercialization technologies for early shipment of product samples.」

「In addition to improving the performance of the cathode material for all-solid-state lithium-ion batteries developed in the previous consolidated fiscal year, we advanced the development of commercialization technologies for early shipment of product samples.」
