Special Feature:Front-Runner Strategy in the Highly-Reliable Small Battery Sector

Becoming the Front-runner in the Highly-Reliable Small Battery Sector

With our refined technological expertise and know-how, Maxell will aim to become Global No. 1 in both scale and advanced technology in the highly-reliable small battery sector, including all-solid-state batteries

Creating new markets through the development of higher value-added batteries, including all-solid-state batteries

Expansion of scale

Acquired the primary battery business from Murata Manufacturing and established “Maxell Sakura Co., Ltd.”
Expanding global share by enhancing competitiveness in quality, cost, and delivery (QCD)*1 and accelerating development themes

In March 2026, we acquired the primary battery business from Murata Manufacturing Co., Ltd., and established Maxell Sakura Co., Ltd. In the near term, we aim to build a flexible production system across the two sites, including Maxell Ono Works, to quickly expand supply capacity and sales. Over the medium term, we aim to generate technological synergies by integrating our respective design philosophies and quality control approaches and create novel products and production technologies that are not merely an extension of existing approaches. We will bring about significant synergies that go beyond the simple sum of the capabilities of the two sites to capture growth opportunities in the market.

Maxell Ono Works Strength in manganese dioxide lithium batteries (CR batteries*2)/ Maxell Sakura Strength in silver oxide batteries (SR)
  • *1 QCD: An acronym for the criteria used to evaluate products, namely quality, cost, and delivery
  • *2 CR batteries: Compact, lightweight batteries with an operating voltage of 3V and a wide operating temperature range.
    They are widely used as a power source in various electronic devices, including IoT sensors and medical equipment.

Pursuit of advanced technologies

Collaborating with JAFCO to strengthen access to external advanced technologies
Actively incorporating necessary technologies to accelerate the evolution of small batteries

In March 2026, we decided to invest a total of 1.0 billion yen over 10 years in a venture capital fund managed by JAFCO Group Co., Ltd. JAFCO’s cumulative number of companies it has helped bring public is among the largest in Japan. JAFCO also excels at supporting the management of startups and facilitating collaboration between them and its investors. By tapping into JAFCO’s network, Maxell will engage in co-creation with startups that possess a wide range of advanced technologies, accelerating our acquisition of innovative technologies in the small battery sector, the creation of new products and businesses, and the optimization of QCD.

  • Collaborating with JAFCO, a leading Japanese venture capital firm
  • Extensively exploring collaboration opportunities with more than 4,000 advanced technology startups through JAFCO’s network
