The risks posed by lithium-ion batteries due to their high capacity

The electricity storage systems offered by ELIIY Power are renowned for their high levels of safety and reliability, and are the go-to choice for home use, as well as various industries including security, communications, hospitals, welfare facilities, government offices and mobile applications. We believe this is in recognition of the safety record we have maintained since our founding: no serious incidents caused by batteries.

Small lithium-ion batteries are widely used in smartphones, PCs and tablet devices. They are known for their lightweight, high-capacity qualities and in recent years have even started to be used in electric vehicles. But as frequent news reports show, there are concerns regarding their safety due to cases of batteries starting to smoke or ignite during use.

Achieving high levels of safety

From our homes to companies, facilities and social infrastructure, batteries are used in every facet of our modern lives. In keeping with its philosophy that the battery itself must be safe, ELIIY Power pursues development by first placing the highest priority on safety.

Our electricity storage systems are equipped with battery cells produced by our plants in Japan and pass stringent safety standards ensuring they will not smoke or catch fire even when punctured with a nail, crushed or overcharged. These features prevent secondary damage due to natural disasters or other unexpected accidents.
