Maxell has announced the development of an ER battery-sized all-solid-state battery module designed to support wireless charging. The company said the new module reflects continued progress in solid-state battery technology for compact power applications, where space efficiency, safety, and charging convenience are key considerations.
The ER battery size format is commonly associated with industrial and electronic devices that require a reliable energy source in a relatively small form factor. By adapting all-solid-state battery technology to this size, Maxell is targeting use cases that benefit from both high packaging efficiency and simplified charging infrastructure. Wireless charging support is a notable feature of the module, as it may reduce the need for frequent physical connector use and help enable more flexible device integration.
All-solid-state batteries differ from conventional lithium-ion batteries in that they use a solid electrolyte rather than a liquid one. This design is widely viewed as promising for improving safety and supporting new battery architectures, particularly in applications where durability and compactness are important. Maxell’s announcement adds to broader industry efforts to commercialize solid-state battery technologies across consumer, industrial, and mobility-related markets.
The development also highlights ongoing interest in battery modules that can be more easily integrated into next-generation electronic systems. As wireless power transfer becomes more common in connected devices and equipment, battery designs that align with those charging methods may help simplify product design and improve user convenience.
Maxell did not indicate in the provided information any commercialization timeline, production scale, or target market details for the module.
