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.

How It Works?

Rechargeable batteries store chemical energy, which can be converted on demand into electric current. That demand is created when some degree of controlled contact is established between the battery’s two terminals. Each external terminal on the battery is paired internally with another material. One contact goes to a type of material that will lend excess electrons under the right conditions, and the other contact goes to a different type of material that will happily accept those electrons under those same conditions. The internal metals are very thin sheets that are rolled together. A thin barrier prevents the two metals from making direct contact with one another. Fundamental to the stability and safety of the battery, this barrier is where the electrolyte is found.

Risk

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.
