Are lithium batteries better than lead acid batteries?

Introduction Are lithium batteries better than lead acid batteries? In terms of performance, application scope and environmental pollution, lithium batteries are better batteries than lead-acid batteries. The specific reasons will be discussed here.

Are lithium batteries better than lead acid batteries?

In terms of performance, application scope and environmental pollution, lithium batteries are better batteries than lead-acid batteries. The specific reasons will be discussed here.

1. The performance of lithium batteries is better

The performance of lithium batteries is mainly reflected in the following three aspects. :

1) Service life

The lithium battery has good temperature performance and can be used at relatively low temperatures and can also be normally used at high temperatures and does not affect the service life, so lithium batteries have a longer service life than lead-acid batteries. Usually, lithium batteries have a lifespan of more than 6 years, while the average lifespan of lead-acid batteries is only about 2 years. a difference of almost 3 fois is definitely an advantage.

Another point is that lithium batteries do not have battery memory effect, so there will be no reduction in battery capacity caused by memory charging like lead-acid batteries.

Lithium batteries have a long lifespan

2) Battery life

Lithium batteries have very high storage energy density and therefore due to the high voltage platform it is easy to form a battery power pack for use in various devices. Lithium batteries are small in size and charge relatively quickly, while lead-acid batteries are large in size, charge slowly, and consume power quickly, so the battery life is much less than that of lithium batteries.

Lithium batteries have good autonomy

3) Resistantovercharge

Qualified lithium batteries can be charged continuously at normal temperatures. There will be no serious problems such as battery expansion, leakage or rupture within 48 hours, but lead-acid batteries cannot suffer from such overcharging, which will cause serious consequences.

Resistant to overload

2. Lithium batteries have a wider range of applications

Lithium batteries are lightweight and relatively small. in size, easy to carry, which determines that lithium batteries of the same volume can have higher capacity than lead-acid batteries, which can improve the endurance of related equipment, so that they can be used in more fields, such as electric vehicles, mobile phones, cameras and other electronic supplies, etc.

Lithium batteries are morewidely used

3. Lithium batteries cause less environmental pollution

In terms of environmental pollution Compared to lead. -Lithium batteries are cleaner and more environmentally friendly. Lithium batteries do not contain heavy metals such as lead and mercury. They will not cause major environmental pollution during production, use and disposal. This will cause a lot of damage to the environment. A big impact, although lead-acid batteries can be recycled, heavy metal pollution remains a serious problem.

In summary, lithium batteries are better than lead acid batteries in terms of performance, application and environmental impact. However, the shortcomings of lithium batteries are also obvious. For example, the safety of lithium batteries is poor, especially cellare of poor quality. Batteries present a risk of explosion and fire. Production conditions are demanding and the cost is high. Therefore, the price is naturally much higher than lead, and lithium batteries cannot be recycled.

Lithium batteries also have many disadvantages

So even though most of the conditions of lithium batteries are better than lead acid batteries, you should always choose according to your actual situation. A battery that suits you.

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

1. Different lifespans

The lifespan of lead-acid batteries is generally about 2 years, and lithium batteries have a strongdurability 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

Typically, 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 electrolyte solutionnon-aqueous.

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. During charging, electrical energy is converted into chemical energy and during discharging, chemical energy is converted into electrical energy.
