Lithium iron phosphate batteries compared with lithium-ion batteries and traditional lead-acid batteries

In terms of lifespan

The lifespan of lithium-ion batteries is about 4 years, and the number of cycles is about 1,000 times, the lifespan of traditional lead-acid batteries is about 3 years, and the number of cycles is about 300 times, while the lifespan of lithium iron phosphate batteries is about 10 years, and the number of cycles is more than 10,000 times, mainly because of the chemistry of lithium iron phosphate batteries helps to prolong the lifespan, and ensures that in the charging and discharging cycle Mainly because the chemistry of lithium iron phosphate battery helps to prolong the life and ensure reliable performance in the charge/discharge cycle. The service life of lithium iron phosphate batteries is the longest, and it is best to choose lithium iron phosphate batteries when selecting batteries.

Environmental safety

The battery itself is a chemical substance, generally produces two kinds of pollution, the pollution of the excreta in the production process and the pollution of the battery after the end of life, while the lithium iron phosphate battery is not polluted whether it is produced or used, lithium iron phosphate batteries are generally considered to be free of any heavy metals and rare metals, non-toxic (SGS certified), non-polluting, and is the absolute green battery. It is safer in handling and recycling, and reduces the impact on the environment, while for lithium-ion batteries, the batteries contain heavy metals inside, and there is a certain amount of environmental pollution in recycling. Although the traditional lead-acid batteries can be completely recycled without polluting the environment, pollution also occurs in the production of lead-acid battery production or battery leakage.

In terms of volume and weight

Lithium iron phosphate batteries in the same volume, the weight is about 50% lighter than traditional lead-acid batteries, but not as light as lithium-ion batteries. However, lithium iron phosphate batteries are portable, can improve space utilization, and can be applied to a variety of fields, and the performance will not be affected.

In terms of maintenance

Lithium iron phosphate batteries do not require regular maintenance, only need to physically check the battery, lithium-ion batteries are also maintenance-free, for lead-acid batteries, some of which require maintenance, such as liquid-rich lead-acid batteries, the need to fill electrolyte or distilled water, etc., and there are also some colloidal batteries, maintenance-free lead-acid batteries and so on do not require maintenance.

In terms of efficiency and performance

The energy density of lithium iron phosphate batteries is lower than that of lithium-ion batteries, but much higher than that of lead-acid batteries, which can store more energy, and the self-discharge rate is lower than that of both lithium-ion batteries and lead-acid batteries, which ensures stable power output over a long period of time.

In terms of deep discharge capacity

The depth of discharge of lithium iron phosphate batteries can reach 100%, and the depth of discharge of lithium-ion batteries can reach more than 80%, while the depth of discharge of traditional lead-acid batteries can only reach about 30%, which means that lithium iron phosphate batteries are able to have more capacity, and can provide more power.

In terms of safety

Lithium iron phosphate batteries are famous for their safety and stability performance, and they do not heat up or form oxidizing substances like other batteries at high temperatures or when overcharged, so they have good safety. There will be no explosion in normal use, only when the battery receives external puncture or short-circuit situation, the battery may appear burning phenomenon, there is also in the overcharging, charging voltage is higher than the standard voltage several times may occur when the explosion phenomenon.

The safety performance of lithium-ion batteries is lower than lithium iron phosphate batteries, prone to thermal runaway phenomenon, cannot be overcharged and overdischarged. Lead-acid battery management system lacks overcharge protection for the battery when charging, many chargers cannot do after full power cut-off, in the overcharge explosion is more likely than lithium-ion batteries, in addition, lead-acid batteries electrolyte for the highly corrosive sulfuric acid, leakage or explosion, the harm is greater than lithium batteries.

Conclusion

The main advantages of lithium iron phosphate batteries are high safety performance, high energy density, can be quickly charged, long service life, etc., can be used in a variety of fields, to maximize the protection of life safety and equipment safety. So, we recommend using lithium iron phosphate batteries, you can also choose the right battery according to your needs.
