Lithium batteries are better. Lithium batteries, whether in terms of volumetric energy or weight energy, are more than three times higher than lead-acid batteries. Lithium batteries are smaller in size and lighter in weight. Long cycle life.

Whether you can run far or not depends on the battery capacity. It's meaningless to just talk about who is far alone.

For example, both are 48V20AH, and lithium batteries and lead-acid batteries are basically the same because they have the same capacity, but lithium batteries are lighter, so they can be slightly farther than lead-acid batteries.

But if the lithium battery is 48V10AH and the lead acid is 48V20AH, then the lead acid is definitely far away, needless to say. Simply put, whoever has a large capacity can run far. The advantage of lithium batteries over lead-acid is that they are lighter and can discharge large currents, and everything else is the same.

Can you search for the safety of lithium batteries after being connected in series with a large capacity? Cost feasibility? Why does mobile phone batteries explode? Although lead-acid batteries are bulky, their stability is much stronger 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 heavily polluting commodity!

1、 At present, the number of lead-acid batteries for electric forklifts on the market is still higher than that of lithium batteries, possibly due to the relatively high cost of lithium batteries. Therefore, in the design of existing "lithium-ion forklifts" products, reducing the capacity of lithium-ion batteries is often used to correspondingly reduce the implementation cost of the entire vehicle, which makes the existing "lithium-ion electric vehicle" products too simplistic.

Lead acid batteries and lithium batteries cannot be solely judged by their quality. Each has its own advantages and disadvantages and is suitable for different needs. At present, most lithium-ion products on the market are "electric bicycles" and the range is not very far. However, models with longer ranges such as four-wheel electric vehicles and four-wheel elderly electric scooters are still more suitable for "lead-acid batteries".

2、 Lithium ions mainly work by moving between the positive and negative electrodes. During the charging and discharging process, Li+is intercalated and deintercaled back and forth between the two electrodes: when charging the battery, Li+is deintercaled from the positive electrode, embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium rich state; When discharging, the opposite is true. Generally, batteries use materials containing lithium as electrodes, and currently, graphite is the most commonly used negative electrode. Compared with lead-acid batteries, lithium batteries have advantages such as light weight, large specific capacity, and long cycle life. As a power source for elderly electric commuting vehicles, they are not only lightweight, portable, and convenient to charge, but also contribute to the "lightweight and minimalist" design of vehicle products.

3、 The electrodes of lead-acid batteries are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the charged state of lead-acid batteries, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; In the discharge state, the main component of the positive and negative electrodes is lead sulfate.

4、 The two types of batteries are different except that they both belong to energy storage devices. Lead acid batteries are safer and cheaper, but their energy density is lower than that of lithium batteries, so their volume is larger. At present, before breakthrough progress has been made in battery (energy storage) technology research, that is, before "low-cost, high-performance" batteries are put into commercial practical applications, the excellent characteristics of existing lead-acid batteries and lithium batteries can be combined for transformation and upgrading, as the main research topic at present and in the future. I believe this has a clearer direction for the future development of electric scooters for the elderly, and even the entire electric scooter industry.

Lead acid batteries are commonly used in electric forklifts. Mainly because of its high cost-effectiveness.

If we want to talk about battery life, other conditions are exactly the same, and the battery capacity is also the same, then it may be because lithium batteries are a bit better. Why? Because lithium batteries are lighter, the whole car is lighter, and of course, they can run a little further.

But I still recommend lead-acid. The main reason is:

1、 Cheap. Generally speaking, a set of lead-acid only costs a few hundred yuan, and a set of lithium batteries, which can be used casually, costs over a thousand to nearly two thousand yuan.

2、 Safety. Do you remember the news two years ago that the woman in Nanjing was riding a lithium-ion battery electric vehicle, and because it was too hot, the lithium-ion battery behind the seat exploded, causing her buttocks to explode?

3、 Lead acid is enough. Nowadays, lead-acid generally has a range of 50-60 kilometers, which is sufficient for household use. Lithium ion batteries are really unnecessary.

Normally, lead-acid battery packs weigh between 16-30 kilograms and have a larger volume; Lithium batteries generally weigh 2.5-3.0 kilograms and have a relatively small volume, making them easy to ride and transport. From a quality perspective, it is difficult to determine the quality of the two, but consumers can purchase high-quality batteries produced by legitimate manufacturers according to their actual needs.

The cost of main materials such as positive electrode materials, negative electrode materials, current collectors, separators, electrolytes, etc. for lithium batteries is much higher than that of lead-acid batteries. The cost of assembly accessories and external circuit systems for lead-acid batteries is extremely low.

Due to the manufacturing process, the labor cost of lithium batteries is relatively high. In the manufacturing cost, the labor cost of lithium batteries accounts for over 40%, while the labor cost of lead-acid batteries is generally 10% to 20%.

The mechanical equipment used in the production of lithium batteries is expensive and of high value, resulting in significant depreciation losses. Most processes in the production of lithium batteries are irreversible, while lead-acid batteries are reversible for repair and reuse. The recycling value of lead-acid batteries after use is over 40%, while the recycling value of lithium batteries is almost zero.

Lithium batteries, whether in terms of volumetric energy or weight energy, are more than three times higher than lead-acid batteries. Lithium batteries are smaller in size and lighter in weight. Long cycle life. The cycle life of lithium batteries used in electric vehicles is generally over 800 times. 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 cost of using lithium batteries, extends their lifespan, and improves their convenience of use. Has a wide range of charging efficiency. This is a unique advantage of lithium batteries. When needed, the charging time can be controlled within 20 minutes to 1 hour, and the charging efficiency can reach over 84%. On the basis of further technological innovation, this feature will be better utilized.

At present, the energy density of lithium batteries is generally between 200-260wh/g, and lead-acid is generally between 50-70wh/g. Therefore, the weight energy density of lithium batteries is 3-5 times that of lead-acid batteries. This means that for the same capacity, lead-acid batteries are 3-5 times that of lithium batteries. Therefore, in terms of lightweight energy storage devices, lithium batteries have an absolute advantage
