Business Opportunities

  • Trends toward cordless power tools and gardening tools, as well as shift to decarbonization (from gasoline engines to batteries and motors)
  • Greater demand for small batteries for automotive, medical, wearable devices and IoT applications
  • Utilization of natural energy, in-house consumption of electricity, and backup power supplies during power outage


  • High-quality, high-output technology
  • Packaging technology that enables impact resistance and miniaturization


  • Market entry and expansion by competitors in our target markets

Murata’s lithium ion secondary batteries are classified into three types: cylindrical, laminated, and small batteries.

Cylindrical type batteries are reliable, keep for a long time, have high temperature characteristic and have advantages particularly in high-power applications. To leverage these characteristics, Murata focuses on the markets for the driving system and storage batteries that are growing in line with decarbonization. Currently, small engines are used for driving systems (for electric tools, gardening tools, etc.), however, it is difficult to control emissions with them. In accordance with the movements towards decarbonization, petrol engines are being replaced with batteries/motors. As for the storage battery market, Murata will expand its business not only for residential use but also for companies, promoting an integrated energy management system of solar power, storage battery modules, and power converter technologies. This energy management system will be introduced at Murata’s own offices and facilities, thereby aiming for 100% renewable energy used in the business activities by 2050, contributing to the realization of a sustainable society.

ILaminated type batteries can be freely changed in size owing to the laminate film exterior material. In addition, gel electrolytes are highly safe because they do not easily leak or swell. They are employed in mobile devices including tablet PCs and gaming devices.

The use of small batteries for the Tire Pressure Monitoring System (TPMS), medical devices and IoT is increasing due to their compactness and reliability. Demand for small batteries is expected to increase especially for wireless earphones and hearing aids. Murata will continue to provide safe and reliable batteries, adding fully solid-state batteries to our lineup that we developed applying manufacturing technology gained from multi layer ceramic capacitors and materials technology acquired through lithium-ion batteries.

Although the fiercely competitive environment is expected to continue in the lithium ion secondary battery market, demand is projected to grow continuously. We will provide batteries that can satisfy our customers and contribute to the realization of a decarbonized society by leveraging the competitive advantages of our batteries, such as high safety, high input/output and high capacity characteristics.
