There’s been a lot of confusion about lithium-ion batteries and what is safe for a UPS. We have developed a quick comparison guide to help you understand the difference between lithium-ion battery types. Certain lithium batteries, e.g. lithium polymer, are best suited for consumer electronics, like your laptop. We explain why LiFePO4 (lithium iron phosphate) is the safe and best lithium-ion battery type for UPS battery backup.
The difference is the following: lithium polymer and lithium cobalt oxide (LiCoO2) used in consumer electronics have a high energy capacity, but as news outlets have reported, they can be flammable. A recent Wall Street Journal article, “Electric-Car Battery Fires Complicate Wider Rollout,” illustrates the potential safety dangers of certain lithium-ion batteries. These batteries have heat issues, called ‘thermal runaway,’ which can lead to combustion.
LiFePO4 – Safe Lithium-ion Battery Type
This is why a LiFePO4 UPS is the best battery backup solution. Lithium iron phosphate is a very stable chemistry that is not subject to thermal runaway and combustion. It is also safe and non-toxic for the environment since it has no caustic materials or dangerous odors.
The LiFePO4 UPS also features key advantages vs. UPS with lead-acid batteries, including:
- 10-year+ service life
- 3 to 4 times longer battery runtime
- Small, lightweight footprint
Falcon Electric has specifically selected highly reliable LiFePO4 batteries for our UPS product families.
