What types of batteries are there?

In the world of energy storage, there are several battery types that are commonly used. The most commonly used are lithium-ion batteries, known for their high energy density, long life and efficiency. There are also salt batteries, which are interesting because of their environmentally friendly nature, and traditional lead-acid batteries, which are less efficient but are still used in certain applications. For a deeper understanding, check out our article on the salt battery.

Why does Frax choose lithium-ion batteries?

Frax works primarily with lithium-ion batteries because this technology offers the best balance between performance, reliability and scalability. Lithium-ion batteries are well suited for intensive use and can withstand thousands of charge and discharge cycles. They are compact, powerful and easy to integrate into plug-and-play solutions. This makes them the ideal foundation for our Battery Energy Storage Systems (BESS), which help companies intelligently manage peak voltage and grid congestion.

Alternative battery technologies

In addition to lithium-ion, alternative battery technologies continue to develop. Salt batteries and flow batteries offer interesting perspectives for specific situations, especially when sustainability and safety are priorities. Frax closely follows these innovations so that we are always ready to provide our customers with the most forward-looking solutions.
