Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume specific energy or weight specific energy. Lithium batteries are smaller and lighter, and Long cycle life. So if you ask me which is better between Lithium Battery Or Lead-Acid Battery?I’d loike to see lithium batteries are better.
Running far is not far, the key depends on the battery capacity. It is meaningless to say who is far.
For example, they are all 48V20AH. Lithium batteries and lead-acids are basically the same, because the capacity is the same, but lithium batteries are lighter, so they can be slightly farther than lead-acid.
But if the lithium battery is 48V10AH and the lead-acid is 48V20AH, then the lead-acid is definitely far away, needless to say. To put it simply, whoever has the largest capacity can run farther. The advantage of lithium battery over lead-acid is that it is lighter and can discharge at a large current, and the rest are the same.
Can you search for the safety of lithium batteries with large capacity in series? cost feasibility? Why do mobile phone batteries explode? Although lead-acid batteries are bulky, they are much more stable than lithium batteries! The cost is basically acceptable! Stability, safety and cost are higher than lithium batteries! As long as it is a battery, whether it is a lithium battery or a lead-acid battery, it is a heavy polluting commodity!
- At present, the number of lead-acid batteries for electric vehicles on the market is still higher than that of lithium batteries. The reason may be that the cost of lithium batteries is still relatively high. Therefore, in the design of the existing “lithium electric car” products, the capacity configuration of lithium batteries is often reduced to correspondingly reduce the implementation cost of the whole vehicle, which makes the models of the existing “lithium electric car” products too simple.
Lead-acid batteries and lithium batteries cannot simply be judged as good or bad. Both have their own advantages and disadvantages and are suitable for different needs of people. At present, most of the lithium battery products on the market are “electric bicycles” and the range is not very long. However, such as four-wheeled electric vehicles and four-wheeled electric scooters for the elderly, they are more suitable for “lead-acid batteries”.
- Second, lithium ions mainly rely on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ is intercalated and deintercalated back and forth between the two electrodes: when the battery is charged, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true. Generally, batteries containing lithium element are used as electrodes. At this stage, the most negative electrodes are graphite. Compared with lead-acid batteries, lithium batteries have the advantages of light weight, large specific capacity, and long cycle life. “Lightweight and simplified” design.
- The electrodes of lead-acid batteries are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. In the charged state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharged state, the main component of the positive and negative electrodes is lead sulfate.
- Fourth, the two batteries are different except that they are energy storage devices. Lead-acid batteries are safer and cheaper, but have a lower energy density than lithium batteries, so lead-acid batteries are larger. At this stage, before the research on battery (energy storage) technology has achieved breakthrough progress, that is, before the “low-cost, high-performance” battery has not been put into commercialized practical application, the existing lead-acid batteries and lithium batteries can be used. The transformation and upgrading of the excellent characteristics are combined as the main research topic for the present and the next period of time. It is believed that this will have a clearer direction for the development of electric scooters for the elderly and even the entire electric scooter industry in the future.
Lead-acid batteries for general electric vehicles. Mainly because of its high cost performance.
If you want to talk about battery life, other conditions are exactly the same, and the capacity of the battery is the same, it may be that the lithium battery is a little better. Why, because the lithium battery is lighter, the weight of the whole car is lighter, and of course it can run farther.
But I still recommend lead acid. The main reason is:
Firstly, it’s cheap. Generally speaking, a set of lead-acid is only a few hundred yuan, and a set of lithium batteries is more than one thousand and nearly two thousand yuan.
Second, safety. Do you still remember the news that the woman in Nanjing was riding a lithium battery electric car the year before, because the weather was too hot, and the lithium battery behind the seat exploded, blowing up her butt?
Third, lead acid is enough. The current lead-acid generally has a battery life of 50 to 60 kilometers, which is enough for home use. Lithium batteries are really unnecessary.
Under normal circumstances, lead-acid battery packs weigh 16-30 kg and are relatively large in size; while lithium batteries generally weigh 2.5-3.0 kg and are relatively small in size, so they are light to ride and easy to carry. From the quality point of view, it is difficult to define the quality of the two, but consumers can buy high-quality batteries produced by regular manufacturers according to their actual needs.
The cost of main materials such as positive electrode materials, negative electrode materials, current collectors, separators, and electrolytes of lithium batteries is much higher than that of lead-acid batteries. The cost of assembly auxiliary materials and external circuit systems of lead-acid batteries is extremely low.
Due to the manufacturing process, the labor cost of lithium batteries is relatively large. In the manufacturing cost, the labor cost of lithium battery accounts for more than 40%, while the labor cost of lead-acid battery is generally 10% to 20%.
The machinery and equipment used in the production of lithium batteries are expensive and of high value, and the depreciation and loss of machinery and equipment are relatively large. Most of the processes in the production of lithium batteries are irreversible, while lead-acid batteries are reversibly repaired and reused. The recycling value of lead-acid batteries after use is more than 40%, while the recycling value of lithium batteries is almost zero.
Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume specific energy or weight specific energy. Lithium batteries are smaller and lighter. Long cycle life. The cycle life of lithium batteries used in electric vehicles is generally more than 800 times, and lithium batteries using lithium iron phosphate cathode materials can reach about 2000 times, which is 1.5 to 5 times longer than lead-acid batteries. This greatly reduces the use cost of the lithium battery, prolongs the service life, and improves the convenience of use. It has a wide range of charging efficiency. This is the unique advantage of lithium batteries. When needed, the charging time can be controlled within 20min-1h, and the charging efficiency can reach over 84%. On the basis of further technological innovation, this feature will be better played.

Efficiency Comparison
When contrasting the efficiency and performance of lead-acid and lithium batteries for electrical automobiles, numerous critical factors need to be taken into consideration. These include energy density, charge/discharge effectiveness, power result, and weight.
Lead-acid batteries have remained in use for over a century and are known for their integrity and affordable. Nonetheless, they fall short in several essential efficiency metrics contrasted to lithium batteries. Among the primary negative aspects of lead-acid batteries is their lower power thickness. On average, lead-acid batteries have an energy density of around 30-50 Wh/kg, while lithium batteries flaunt a significantly higher power density, normally ranging from 150-250 Wh/kg. This greater energy density in lithium batteries converts to longer driving arrays for electrical vehicles.
One more essential aspect is the charge/discharge efficiency. Lead-acid batteries usually have a charge performance of about 70-80%, suggesting a noteworthy section of power is lost throughout the billing procedure. On the other hand, lithium batteries provide a much higher fee performance, often going beyond 90%. This remarkable effectiveness not just boosts the total performance of the electric vehicle but likewise contributes to much faster billing times.
When it concerns power results, lithium batteries once more surpass lead-acid batteries. Lithium batteries can supply high power outcomes consistently, which is vital for the quick velocity and sustained high-speed driving called for by modern-day electrical autos. Lead-acid batteries, on the other hand, have a tendency to have a reduced power outcome, which can impact the lorry’s efficiency, especially under hefty tons problems.
Weight is another significant factor in performance and efficiency. Lead-acid batteries are significantly heavier, which can negatively affect the automobile’s performance by increasing the general weight. The lighter weight of lithium batteries contributes to enhanced vehicle performance and handling, providing a better driving experience.

Nonetheless, this reduced various lasting economic considerations that counteract advance expense.
Lithium batteries, while much more expensive initially, offer several economic benefits over their lead-acid counterparts. One of the main benefits is their greater power thickness, which equates to longer driving ranges and lowered charging frequency. This efficiency can lead to considerable financial savings on electrical energy prices gradually.
Another important aspect is the lifespan of the batteries. Lead-acid batteries commonly have a shorter life span, requiring a substitute every 3 to 5 years. On the other hand, lithium batteries can last as much as 10 years or even more, depending on use patterns and maintenance. Although the preliminary cost is more significant, the longer life expectancy of lithium batteries means fewer replacements, minimizing ownership’s overall price over time.
Upkeep expenses additionally vary substantially between the two sorts of batteries. Lead-acid batteries need routine maintenance, including inspecting water degrees and ensuring proper billing to prevent sulfation. On the other hand, lithium batteries are primarily maintenance-free, which can further lower continuous prices and inconvenience electrical vehicle owners.
In addition, the price of disposal and recycling must be considered. Lead-acid batteries have poisonous materials, which demand mindful handling and disposal, frequently sustaining additional costs. Lithium batteries, while not without environmental worries, typically have lower disposal expenses and are much more amenable to reusing technologies, which can minimize a few of these expenditures.
In recap, while the preliminary purchase price of lead-acid batteries may be appealing, the long-term price advantages of lithium batteries, including reduced upkeep, longer life expectancy, and decreased power costs, frequently make them an extra financially viable option for electrical vehicle owners.
