Technology / Lithium VS Lead-Acid

The most comprehensive lithium iron phosphate battery ever compared to the advantages of lead-acid batteries. The lithium battery pack is a new battery that can extend the range of the last few years by public recognition. Lithium iron phosphate as lithium battery cathode material, is currently the safest lithium battery cathode material, due to its safety and stability, lithium iron phosphate has become an important development direction of lithium power lithium batteries.

★Small size and lightweight

The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery, and the weight is light, only 1/3 to 1/4 of the lead-acid battery.

★Long cycle life

The cycle life of the lithium battery is 2000+ times, but the cycle life of the traditional lead-acid battery is only 500-900 times.

★Good charge and discharge characteristics

Lithium battery pack charge and discharge electrical energy conversion efficiency can be greater than 97%, lead-acid battery charge and discharge electrical energy conversion efficiency of about 80%. About the same fully charged lithium iron phosphate ion battery, at the same temperature, using different multiples of the discharge current, its discharge output characteristics are very stable.

★Safety and environmental protection

Lead-acid batteries: containing lead, antimony, and other heavy metals, causing serious pollution to the environment, use, and maintenance prone to leakage, internal sulfuric acid spillage resulting in equipment corrosion, and personnel injury accidents.

Lithium iron phosphate ion battery: lithium iron phosphate materials do not contain any heavy metals and rare metals, non-toxic, both in production and use are pollution-free, in line with European RoHS regulations, for the green battery lithium batteries. In the puncture, extrusion, overcharge, short circuit, and other experiments, no explosion, no fire.

★Good performance in use

Lead-acid batteries.

1、Memory effect, can't be charged and discharged at any time;

2, there is a serious self-discharge phenomenon, the battery is easy to scrap after a period of time;

3, in the low-temperature state due to electrolyte freezing, the battery can not be used, in winter the battery;

4、The performance is greatly reduced;

5, the discharge rate is small, can not be a long time high current charge and discharge.

Lithium iron phosphate batteries.

1, no memory effect, the battery can be charged and discharged at any time.

2, low self-discharge battery, monthly self-discharge is less than 1%, the battery can be stored for a long time.

3, wide temperature range, in -20 ℃ -55 ℃ can be used normally, -20 ℃ under the circumstances can be discharged to more than 90% of the rated capacity.

4、Powerful, can be charged and discharged quickly, can be fully charged more than 80% in 20 minutes, and can be discharged in 15 minutes.

★Good high-temperature performance

Wide operating temperature range, lithium iron phosphate ion battery thermal peak up to 350 ℃ -500 ℃, while the lead-acid batteries only at about 200 ℃.

Summary: Compared to lead-acid batteries, lithium-ion battery packs are a whole lot more advantageous. In general, it has the following advantages: small size, lightweight, high energy density, long life, safe to use, high current fast charging, high and low-temperature resistance, large depth of discharge, green, and no memory effect.
