Semi-Solid State Battery Technology

Semi-Solid State NMC batteries are an evolutionary leap in lithium-ion battery technology, delivering superior safety and capacity compared to their predecessors, and that’s why we’ve chosen to offer Semi-Solid State batteries in our new SuperBase V home energy storage system.

Lithium Iron Phosphate Batteries

Lithium iron phosphate batteries have long been a popular choice in reusable energy storage. They are reliable, relatively inexpensive, and easy to integrate. But many options currently available can pose a safety hazard if they are damaged. And it all comes down to the electrolyte.


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.

Semi-Solid State Battery

Needless to say, the scientific and engineering communities are constantly researching and experimenting with ways to make a safer battery without compromising on performance. Semi-Solid State battery technology represents a massive breakthrough on both fronts.

Safer Battery with High Performance

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

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.
