LiFePO4 vs Lithium Ion: Which Battery Should You Choose?

LiFePO4 and nickel-based lithium-ion batteries compared by cycle life and energy density

LiFePO4 vs lithium ion is usually framed as two separate battery types, but LiFePO4 is a lithium-ion chemistry. The useful comparison is lithium iron phosphate, shortened to LFP, against the nickel-based lithium-ion chemistries commonly used where size and weight matter. For backup power and frequent cycling, I would usually choose LFP. For a device that … Read more
