Trend: Lithium Batteries Replace Lead-acid


Trend: Lithium Batteries Replace Lead-acid

From the perspective of environmental protection, the pollution of lead-acid batteries can not be avoided. Lead plate and sulfuric acid solution of the lead-acid battery are difficult to degrade. The safety of lead-acid batteries and the reduction of range caused by battery attenuation are also a headache for the court. Taking a double-seat golf cart as an example, the common golf cart on the market is equipped with 6 175Ah lead-acid batteries. The mileage of new vehicles equipped with such batteries is about 40km after being fully charged. However, with the increase of the service time of the golf cart, the charging and discharging capacity of the battery will be worse and worse, even less than 10km. The decrease in the range of the service life will greatly affect the normal use of the golf cart. These problems in lead-acid batteries can not be solved from the technical point of view, but things have changed after the emergence of lithium batteries. It is inevitable to replace lead-acid power batteries with lithium batteries. We share some knowledge and give a brief introduction to the advantages of lithium batteries used in golf carts below.

Lithium Battery

As a high and new technology enterprise focusing on the field of green energy, our company is dedicated to the research and manufacture of the lithium iron phosphate battery and tries to provide you with high-quality and reasonable price products and services. Here are some characteristics of our lithium phosphate batteries.

High Capacity & High Output Voltage

When the battery works under the condition of incomplete discharge, the capacity will quickly fall below the rated capacity. This phenomenon is called memory effect. For example, Ni-MH and Ni-Cd batteries have memory, while lithium iron phosphate batteries do not. No matter what state the battery is in, it can be used as soon as it is charged, and there is no need to discharge it before charging.ia

Small Size & Light Weight

The volume of the lithium iron phosphate battery with the same specification and capacity is 2/3 of that of the lead-acid battery, and the weight is 1/3 of that of the lead-acid battery.

Long Life

The cycle of a long-life lead-acid battery is about 300 times, up to 500 times, while our lithium iron phosphate battery has more than 6000 cycles.

High Security & Good High-temperature Performance

The electrothermal peak of lithium iron phosphate can reach 350℃- 500℃, while that of lithium manganate and lithium cobalt oxide is only about 200℃. The P-O bond in lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperatures or overcharge, it will not collapse and heat like lithium cobalt oxide or form strong oxidizing substances.

Environment Protection

Lithium iron phosphate battery is generally considered to be free of any heavy metals and rare metals. It is clean and green energy pose no toxic, no pollution to environment.


Cost: Lithium Batteries VS. Lead-acid

The actual working performance of the lithium electric golf cart is commendable. First, although the upfront cost of lithium batteries is relatively high, compared with the comprehensive cost of lead-acid batteries, the golf cart used lithium batteries is more economical in the service life. During the service life, the lithium battery does not need to be replaced in the middle, while the lead-acid battery needs to be replaced in about two years. In addition, the daily maintenance cost of the lead-acid battery is very high, and the battery liquid needs to be added frequently. Once the maintenance is not in place, the lead-acid battery is easy to damage. The cost of maintenance and replacing lead-acid batteries is much higher than that of using lithium batteries. Second, the lithium battery attenuation is almost negligible, and the vehicle can be used frequently. The maintenance of the lithium battery is simple and easy. There is no need to add battery fluid, which saves labor and material. In addition, because the golf carts used lithium batteries are relatively light, the wear of tires, shock absorbers, brakes and other parts is much less.

Simple Introduction Of Lithium Batteries

At present, there are three main types of batteries: lithium manganate, lithium iron phosphate and ternary materials. Lithium manganate is one of the most common cathode materials for lithium batteries. Its poor cycle performance and electrochemical stability greatly limit its industrialization. The ternary battery is a kind of lithium battery with nickel, cobalt, and manganese as cathode materials. Ternary materials combine the advantages of lithium cobalt oxide, lithium nickel oxide and lithium manganese oxide, which have high capacity and low cost. However, the thermal stability of the ternary battery is poor, and it will decompose at high temperatures. And the chemical reaction of ternary lithium materials is particularly strong. Once oxygen molecules are released, the electrolyte will burn rapidly in a high-temperature environment, and then deflagration occurs. Lithium iron phosphate (LiFePO4) has been used as battery material in recent years. Its safety performance and cycle life can not be compared with other materials. Lithium iron phosphate cathode material makes large-capacity lithium batteries easier to use in series to meet the needs of frequent charging and discharging of electric vehicles. In addition, LiFePO4 has the advantages of being non-toxic, non-polluting, good safety performance, wide source of raw materials, and long service life, which is an ideal cathode material for the new generation of lithium-ion batteries. And the LiFePO4 battery works well with solar panels, so you don’t need to worry about maintenance.
