Lithium vs lead acid battery

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 2/8 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

Memory effect, cant be charged and discharged at any time.
there is a serious self-discharge phenomenon, the battery is easy to scrap after a period of time.
in the low-temperature state due to electrolyte freezing, the battery can not be used, in winter the battery.
The performance is greatly reduced.
the discharge rate is small, can not be a long time high current charge and discharge.
Lithium iron phosphate batteries.
no memory effect, the battery can be charged and discharged at any time.
low self-discharge battery, monthly self-discharge is less than 1%, the battery can be stored for a long time.
wide temperature range

in-20 °C-55 °C can be used normally, -20 °C under the circumstances can be discharged to more than 90% of the rated capacity.
Powerful, can be charged and discharged quickly, can be fully charged more than 80% in 20 minutes, and can be discharged in 1 minutes.

Good high-temperature performance

Wide operating temperature range, lithium iron phosphate battery thermal peak up to 850 °C.-800 °C; while the lead-acid batteries only at about 200 °C.


1. 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.

2. There are many lithium batteries on the market, and the more common lithium batteries on the market now are divided into lithium iron phosphate li batteries and ternary lithium batteries. Now, most passenger electric vehicles will choose lithium batteries, the main reason is that lithium batteries higher requirements for safety performance, but also higher requirements for range.

3. We all know that the chemical properties of lithium metal are very active, the use of lithium metal processing, preservation, use, the requirements of environment is very high. So lithium batteries have not been used for a long time. With the development of electronic technology now, miniaturized are increasing, putting high demands on the power supply. Now lithium batteries are also entering the stage of large-scale use.

4. Whether we look at the volume or capacity from the lithium battery is much better. From the point of view of use, the service life of lithium batteries than three times higher than the service life of lead-acid batteries, lead-acid batteries are generally about 3/4 years, while the service life of lithium be is generally about 8/10. Compared to the price of lithium batteries, then the price of lead-acid batteries is also cheaper and can be repaired to continue service life. Although the cost of lithium batteries is much higher than the price of lead-acid batteries, from the long-term view of maintenance costs, lithium bat. are much better than lead-acid batteries.

5. Well disagree on the safety performance of the battery, some people will feel that the safety performance of lead-acid batteries than lithium batter some people feel that lithium batteries to be better than lead-acid electromagnetic, this depends on personal views. | think lithium batteries will be better than lead-acid batteries, whether, in terms of safety performance or weight, lithium batteries have an advantage over lead-acid batteries.
