Maxell, Ltd. (TOKYO: 6810) has launched a joint development project with researchers led by Specially Appointed Professor Yosuke Shiratori of the Institute of SCIENCE TOKYO (hereinafter “SCIENCE TOKYO”) on next-generation batteries utilizing an Aqueous Composite Quasi-Solid Electrolyte (3D-SLISE).

Because this next-generation battery does not use flammable organic electrolytes, it is expected to offer a reduced risk of fire. 3D-SLISE is an electrolyte containing water molecules at the interfaces between ceramic particles. By mixing it with water to form a slime-like electrolyte, batteries can be manufactured using coating-based processes.
This technology enables the use of coating technologies and production equipment that Maxell has cultivated through the manufacturing of lithium-ion battery electrodes. In addition, because neither dry rooms nor organic solvents are required, it is expected to contribute to reducing environmental impact through lower VOC (Volatile Organic Compound) emissions and reduced power consumption during manufacturing processes.
Furthermore, the battery is expected to offer excellent recyclability as 3D-SLISE can be dissolved in water after use, making it easier to recover active materials.
Potential applications include uninterruptible power supply (UPS) systems for data centers, as well as power tools and automated guided vehicles (AGVs), where stringent safety requirements are essential. In particular, while lithium-ion battery-based UPS systems are increasingly being adopted in data centers to improve energy efficiency and reduce installation space, mitigating fire risks associated with thermal runaway and strengthening fire protection measures remain important challenges. Because even a single fire incident can significantly impact facility operations and business continuity, exceptionally high levels of fire safety are required.
Through this joint research project, Maxell and SCIENCE TOKYO aim to leverage 3D-SLISE, a water-containing aqueous composite quasi-solid electrolyte, to reduce fire risks and improve the safety of people and equipment. They also seek to contribute to reducing the burden associated with fire protection systems and lowering overall facility operating costs in data centers.
