If the battery is damaged, this thin barrier may break, allowing direct contact between the two metals. This contact is called a “short” and creates a huge demand for current. A great amount of heat is generated from the rapid flow of electrons, causing the electrolyte material to liquefy and vaporize. The resulting internal expansion tears apart the barrier, causing more contact, and more rapid heat generation. This runaway chain reaction can result in a fire, burn injuries, and property damage.

In Semi-Solid State battery manufacturing, the chemical solvents used to make the internal compounds remain inside the battery during assembly. These solvents harden and become a solid electrolyte interphase that is more resilient and far less likely to suffer the kind of chain reaction that causes fires and burns in other lithium-ion options. Even when punctured by a metal spike in performance tests, Semi-Solid State batteries tend to be vastly superior in terms of safety than their peers. On top of that, they also hold more energy, pound for pound, than other batteries.

A home energy storage system is, at its core, a very large battery. And larger batteries pose a bigger threat when damaged than smaller batteries because they will burn hotter and longer. In consideration of family safety and peace of mind, we are proud to champion this revolutionary and potentially life-saving technology by being the first company to offer Semi-Solid State batteries in a home energy storage system.
