Talk about the advantages and disadvantages of lithium batteries and lead-acid batteries

Recently, due to a job change, the place to work is relatively close to home, and going out to work every day is a malicious test of my luck. I want to buy an electric bicycle for travel, but I don’t know. I saw that the batteries of electric bicycles are not the same. I saw two types, one is lead-acid battery and the other is lithium battery. For an art student, what is this? But it seems that lithium batteries are more common in life. What are lead-acid batteries?

In line with the idea of u200bu200bresearching if you don’t understand, let’s take a look at the advantages and disadvantages of the two batteries that I have learned briefly:

Lead-acid battery

Principle of power generation: Lead-acid battery is equivalent to the basic substance immobile. According to the state of charge and discharge, the valence of lead ion changes. (This is written in words that I can understand when I consulted the professional. Please correct me if you have any misunderstandings. If you want to understand the specific principles, please encyclopedia by yourself.)

Advantages: Compared with lithium batteries, the price is cheaper, not affected by temperature, and the charging safety is higher. The recycling value is higher. Simply understand that if the lead-acid battery is broken, it can be repaired.

Disadvantages: short battery life, larger volume and heavier weight. The life span is generally about 2 years. Because the material contains sulfuric acid and heavy metals, it is corrosive and easily causes environmental pollution.

Applications in life: automobiles (fuel vehicles), electric bicycles, etc.

Lithium battery

The principle of power generation: Simply put, the charging process of a lithium battery is equivalent to the lithium ion of the positive electrode. When the negative electrode is stored, the discharge process is well understood, that is, the lithium ions in the negative electrode run back to the positive electrode, and the process is reversible. (This is written in words I can understand when I consulted the professional. If you are wrong, please correct me. If you want to understand the specific and detailed principles, please go out and turn left on Baidu Encyclopedia.)

Advantages: Small size, light weight, and more convenient to carry. Better endurance and full power. The general life span is about 4-5 years. It is more environmentally friendly than lead-acid batteries.

Disadvantages: Compared with lead-acid batteries, they are more expensive, have basically no recycling value, and are more severely affected by temperature. () Improper charging can easily cause fires. (For your own safety, it is very convenient for everyone to go to the charging station when charging the electric bicycle.)

Common applications in life: mobile phone batteries, computer batteries, etc. .

There have been countless twists and turns in the middle, and my friend has been crying in the toilet n times. I sorted it out. In summary, I didn’t study well when I was in school, and I will try to make up for it later. I sincerely urge the children who are in school to study hard, otherwise the society will definitely tell you what it means to 'hate less when the book is used'. Okay, let’s stop here today. What else is fun for friends? If you want to know, you can comment and leave a message. I’m going to study it and share it with you.
