The most common type of battery used in energy storage systems is Lithium-ion batteries. Lithium-ion batteries allow you to take electricity generated by the grid, solar panels, wind turbines, or any combination and store it for use when you need it most. However, not all lithium-ion batteries are the same when it comes to reliability and safety.

Even though they are referred to generically as one class of battery, ‘lithium ion’, they can differ significantly in chemistry, cell form-factor, and construction, which can impact their performance dramatically. Learn more about the chemistry of lithium-ion batteries:

• Lithium-ion chemistry: Lithium-ion batteries have a lot of advantages over their lead-acid counterparts. They are lighter, more efficient, charge faster, and have a longer lifespan.
• Lithium Iron Phosphate Battery (LFP): In the energy storage system industry, LFP lithium-ion chemistry is often considered more cost-effective, longer-lasting, and much less prone to thermal runaway than other battery chemistries.
• Thermal Runaway: Thermal runaway begins when the heat generated within a battery exceeds the amount of heat that is dissipated to its surroundings.
  
  It is a thermal runaway that causes overheating, fires, and explosions that are associated with lithium-ion batteries in the market today. Lithium Ferro Phosphate (LFP) chemistry reduces the risk of thermal runaway with fire propagation, operating temperature constraints, and toxic coolants.
  
  While LFP batteries are non-toxic, they can still go into thermal runaway. However, their thermal runaway threshold is much higher but still a very attainable 375 deg F compared to 300 deg F.
• UL9540 Certification: UL 9540 is the most stringent safety standard for battery energy storage systems installed in homes and businesses. UL 9540 takes the guesswork out of understanding system safety and ensures that energy storage devices meet certification requirements specified in building and fire codes. It also provides assurance to customers that their batteries and balance-of-system equipment will perform and not create hazards.
  
  Customers are encouraged to ask any system installer or vendor if their proposed solution is UL 9540 certified – and request a solution that is approved for its safety and performance.
