Lithium iron phosphate batteries can last 2,000-3,000 charge cycles, while lithium cobalt oxide batteries typically last 500-1,000 cycles. The chemistry affects how well the battery structure holds up during repeated charging and discharging. But it's fading from industry use due to fire risks. Key Facts: We only recommend LCO for: For most clients, we suggest switching to safer NMC batteries. With a practical energy density of 150–200 Wh/kg and stable 3. You'll find LCO batteries in smartphones and laptops because they pack a lot of power into tight spaces.
