Which is better lithium or lead acid battery?

The most common electric vehicle batteries on the market now are lithium batteries and lead acid batteries. Whether it is lead-acid batteries or lithium batteries, they have their own advantages and disadvantages, so no one talks about them. It's better. I can only say which one suits you best. After all, everyone's use situation is different. It is recommended to refer to the advantages and disadvantages of lead-acid and lithium batteries and combine them with your actual usage. situation to choose an electric vehicle battery that suits you best. Here are their respective advantages and disadvantages:

Advantages of lead acid batteries:

1. Good safety performance. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.

2. Cheap price. The price of lead acid batteries is about 1/3 of che lithium-ion batteries, which shows how low the price is.

3. Recyclable reverse repair. Lead acid batteries are highly recyclable. Once worn out, you can go to an electric car store to exchange them for new ones. You can exchange them for a new set of batteries by paying the price difference, thus minimizing losses. a great advantage for users. Battery lead can also be recycled and reused, reducing environmental pollution.

Disadvantages of lead-acid batteries: high weight, limited battery capacity and short lifespan. Lead-acid batteries typically have a lifespan of about three years after 400 deep charges and discharges.

Advantages of lithium-ion batteries:

1: Lightweight and small size. The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 ofweight of the lead-acid battery. Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries. The reduced weight makes electric vehicles lighter and their range is increased by around 10%.

2: Long life. The average lifespan of lithium-ion batteries is about 4 years, about a year longer than lead-acid batteries. It can be charged and discharged more than 500 times. The battery has no memory and is very shock resistant.

3: Resistant to overcharge, good resistance to charge and discharge. At normal temperatures, lithium-ion batteries can be continuously charged for 48 hours without causing expansion, leakage, rupture or other accidents, and the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.

Disadvantages of lithium-ion batteries:

The cost of producing lithium-i batteriesone is high, production equipment is expensive, and labor costs account for about 40% of the production cost. The price is about three times that of lead-acid batteries. At three times the price, it's not great value for money, and it looks rather flashy. Additionally, lithium-ion batteries are not recyclable. Once worn out, they can only be thrown away or buried after thousands of times. years, future generations will not be able to use them. If you dig it up, it will be an antique.

The safety performance of lithium batteries is worse than that of lead-acid batteries, especially at high temperatures, they are prone to dangers such as fire, spontaneous combustion and explosion.

Based on product quality, after-sales service and price, we recommend several relatively good lead-acid battery brands: Changxin Battery, Shinhwa Battery and Mantingfang Battery.

Which is better, lead acid battery or lithium battery

The main differences between lead acid batteries and lithium batteries are their different lifespan, different number of charge and discharge cycles, as well as different volume and weight.

1. Different lifespans

The lifespan of lead-acid batteries is generally about 2 years, and lithium batteries have strong durability and are used. The lifespan is generally 4 to 5 years.

2. The number of charge and discharge cycles is different

Lead-acid batteries are generally fully charged and discharged in 400 times and have memory for; lithium batteries are fully charged and discharged 500 times and no memory.

3. Different sizes and weights

Generallyt, lead-acid batteries weigh between 16 and 30 kg and are generally larger than lithium batteries; -3 Kilogram, the volume is relatively small.

How lead-acid batteries and lithium batteries work:

Lithium-ion batteries are characterized by their lightness and ease of transport. Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.

Lead-acid batteries can store limited electrical energy and use it in appropriate locations. Its working principle is to convert chemical energy into electrical energy. It uses a lead plate filled with sponge lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22 to 28% dilute sulfuric acid as the electrolyte. While charging, theelectrical energy is converted into chemical energy and during discharge the chemical energy is converted into electrical energy.

What is the difference between a lead acid battery and a ternary lithium battery

Which is better, a lead acid battery or a ternary lithium battery? lithium batteries

I The electric car I bought uses lithium batteries. My boss told me that I basically use it now. It has a longer lifespan and recharges more quickly. In fact, lead-acid batteries and lithium batteries each have their own advantages and disadvantages. The choice of battery depends on the application scenario and needs.

The advantages of lead-acid batteries are: low cost, mature technology, high safety and recyclability.

The disadvantages are: low energy density, high weight, slow charging speed and short lifespan.

Equipment such as golf carts and electric forklifts that require stable power supply for a long time can use it.

The advantages of lithium batteries are: high energy density, light weight, fast charging and long life.

The disadvantages are: high cost, relatively low safety and non-recyclability.

Drones, submarines, smartphones, tablets, laptops, digital cameras, etc. all use lithium batteries as the main power supply device.

Pacific Automotive Network From a safety perspective, lead-acid batteries do not contain organic electrolytes, and accidents such as fires and explosions do not occur generally not, while ternary lithium batteries have some The sealed space contains gold materialshazards which can cause fires and explosions if used incorrectly. Therefore, in terms of safety, lead-acid battery is better than ternary lithium battery.

From the perspective of safety, lead-acid batteries do not contain organic electrolytes, and fire and explosion accidents generally do not occur; while lithium batteries have a certain sealed space and contain organic materials if used incorrectly. such as fire and explosion may occur.

Therefore, in terms of safety, lead-acid batteries are better than lithium batteries.

From the perspective of energy density, a kilogram of lithium battery contains 3 to 4 times the energy of a kilogram of lead-acid battery. In other words, for the same weight, lithium batteries can travel further than lead acid batteries.

Therefore, in terms of energy density, lithium batteries are better than lead-acid batteries.

From a lifespan perspective, a set of good quality lithium batteries can be cycled about 1,000 times, while lead acid batteries are only about one third of that of lithium batteries.

Therefore, whether it is comparing lead-acid batteries with lithium batteries, or comparing lithium batteries with different materials, they all have their own advantages and disadvantages, and they cannot simply be described as "good" or "bad" definition.

Luyuan-FK2 lead-acid vehicle When buying an electric vehicle, if you do not need to take out the battery to recharge it, you are not looking for a light vehicle and the charging environment is also relatively complex (e.g. it is very hot in summer and very coldin winter), you can choose lead-acid batteries offering greater safety and higher cost.

If you want your vehicle to be lightweight yet capable of traveling long distances, or if you sometimes need to extract the battery to recharge it (in a safe environment), you can choose a Extractable lithium battery with higher power. energy density.
