What is the price difference between lead-acid batteries and lithium batteries? Lithium batteries and lead-acid batteries each have their own advantages and disadvantages. Nowadays, many people have changed the price of lead-acid batteries to lithium batteries. However, when many people hear about the price of lithium batteries, they immediately shake their heads like a wave of drums. Don't worry, it's too expensive. So how much does the price difference between lithium batteries and lead-acid batteries? This article compares the prices of lithium batteries and lead-acid batteries, hoping to be helpful and reference for everyone.

What is the price difference between lead-acid batteries and lithium batteries?

The current mainstream battery in the market is 48 volts. If replacement is needed, lead-acid batteries cost around 380-450 yuan (48V12AH-48V20AH) with a warranty period of 1 year; Lithium batteries are relatively expensive, costing around 1000 (48V12AH) yuan, but their warranty period is 2 years.

Along with the expansion of the usage range of lithium batteries, there is also a confusion in their prices. The prices of lithium batteries produced by some non-standard manufacturers are much lower than those produced by legitimate manufacturers. The following is an example of a table that shows the price difference between lead-acid batteries and lithium batteries. Please refer to the table below.

Overall, lithium batteries are about twice as expensive as traditional lead-acid batteries. In recent years, with the annual decline in the application cost of lithium batteries and the regulation and subsidy of national policies, the price of lithium batteries has dropped to 1.1-1.2 yuan/Wh, and the replacement of lead-acid UPS by lithium battery UPS will accelerate.

The reason for the price difference between lithium batteries and lead-acid batteries:

1. Composition materials of battery cells

The composition materials of lithium battery cells include lithium alloy metal oxide for the positive electrode, graphite for the negative electrode, and electrolyte for non-aqueous electrolyte materials.

The composition materials of lead-acid batteries include lead and its oxide in the positive and negative electrodes, as well as sulfuric acid solution in the electrolyte.

Among these battery cell components, the price of lithium alloy metal oxides is slightly higher than the basic price of lead and its oxides. Although in the past, the price of lithium alloy metal oxides was expensive due to scarcity, with the excavation of lithium minerals, the price of lithium iron phosphate is now lower than before, around 6300-68000 yuan/ton.

2. Processing costs

The production process of lithium battery U is particularly complex, especially in the production process of lithium batteries. There are top and side sealing processes, liquid injection and pre sealing processes, static placement, formation, and fixture shaping processes, which have significant requirements for the machine and production environment of battery production. The production process also requires the cost of manpower and machinery.

The production process of lead-acid batteries includes organic board treatment, high-temperature curing, terminal sealing, and battery airtightness testing. Most of the production steps do not have high requirements for the production environment and machine compared to lithium batteries.

Is lithium batteries really more expensive than lead-acid batteries?

Lead acid batteries: Common cycle times are around 350, with a memory effect and a lifespan of about two years. Due to limited battery capacity, the batteries are too bulky, allowing all users to experience a weightlifting competition. More seriously, the pollution of lead-acid batteries adds a heavy burden to the increasingly harsh environment. However, increasing the consumption tax by 4% this year undoubtedly shortens the prices of lead-acid and lithium batteries.

Lithium batteries: Lithium batteries have a volume that is two-thirds of the volume of lead-acid batteries, and a weight that is about 1/3 of the weight of lead-acid batteries. Lithium batteries of the same volume have a higher capacity than lead-acid batteries, and the reduction in weight increases the endurance of electric vehicles by about 10%. The average lifespan is about 4 years, which is about 1.5 times longer than lead-acid batteries. With more than 500 charges and discharges, the battery has no memory and strong seismic resistance. Under normal temperature, lithium batteries can be charged continuously for 48 hours without accidents such as battery expansion, leakage, and rupture. The capacity is maintained at over 95%. Moreover, with a dedicated charger, they can be quickly charged and discharged, providing a shot in the arm for a racing life.

However, in terms of price, lithium batteries are still more than twice as expensive as lead-acid batteries.

Which is more cost-effective, lithium battery or lead-acid battery?

At present, lithium batteries are about three times more expensive than lead-acid batteries in terms of price. However, based on the analysis of service life, investing the same cost still results in a longer service life for lithium batteries.

Compared to lead-acid batteries, lithium batteries have a higher average voltage and higher energy density. In other words, batteries of the same size have more capacity. In addition, lithium batteries are relatively lightweight, convenient to carry, and have a much longer lifespan. In addition, lithium batteries have stronger adaptability to high and low temperatures, are less affected by temperature factors, and are more environmentally friendly.

The cost-effectiveness of lithium batteries and lead-acid batteries should be a concern for many people. Today, the editor will introduce the prices of lead-acid batteries and lithium batteries. The advantages of lithium batteries include light weight, small size, environmental protection, etc. It is precisely because lithium batteries have many advantages, and their prices are gradually becoming more affordable. With the support of national policies, more and more people are choosing lithium batteries for battery applications.

With the development of technology, the safety performance of lithium batteries will be improved, and there will be standards for the price of lithium batteries. The cost of raw materials for lithium battery production will gradually decrease, and their prices will also gradually decrease.
