Lithium iron phosphate battery
Lithium-ion iron phosphate batteries and lithium-ion batteries are both mainstream battery types on the market today, and they have their own advantages and disadvantages, but in terms of durability, lithium-ion iron phosphate batteries have more advantages.
First of all, lithium-ion iron phosphate batteries have a longer lifespan. In the process of charge-discharge cycle, the attenuation rate of lithium-ion iron phosphate battery is slow, and its capacity can still be maintained at more than 80% after 2000 charge-discharge cycles. The cycle life of lithium-ion batteries is relatively short, usually around 500 times, which is mainly because lithium-ion batteries will form lithium dendrites during charging and discharging, and with the increase of the number of cycles, the number of lithium dendrites will increase, resulting in a gradual decrease in battery capacity. Therefore, under the same conditions of use, lithium iron phosphate batteries can be used for a longer period of time and can withstand more charge-discharge cycles.
Secondly, lithium-ion iron phosphate batteries are more safe. The positive and negative electrode materials of lithium-ion batteries are active substances, if the battery is overcharged, over-discharged or short-circuited, etc., it may cause the electrolyte inside the battery to decompose, produce a large amount of gas and heat, and lead to safety accidents such as battery shell rupture, combustion or **. The cathode material of lithium-ion iron phosphate batteries is lithium iron phosphate, which is a material with good thermal stability and will not decompose or burn even in high-temperature environments. In addition, the electrolyte of lithium iron phosphate batteries does not contain organic solvents, so it does not generate excessive gas and heat, and has higher safety.
Finally, lithium-ion iron phosphate batteries are more efficient in charging and discharging. The charge-discharge efficiency of lithium-ion iron phosphate batteries can reach more than 95%, while the charge-discharge efficiency of lithium-ion batteries is usually around 90%. This means that lithium-ion iron phosphate batteries can be fully charged faster and a large number of charge-discharge cycles can be completed in a shorter period of time.
