What are the classifications of lithium batteries?

What are the lithium batteries? When I first started learning about this product, the company had thousands of product models, which was really incredible.
Later, in the process of familiarizing for many years, I learned that lithium batteries are roughly divided into the following types.

The first is the conventional polymer lithium battery, which is our daily use of mobile phones, tablets, and mobile power sources. We have the most contact. In addition, our lithium batteries can also be used for power tools, household appliances, and robots, Smart home, medical and health products.
There is also a power battery, which is Tesla, BYD, some new energy electric vehicles, and drones and other products. These batteries require a large instantaneous current compared with polymer lithium batteries, and digital batteries cannot meet the instantaneous requirements. High Current.

If divided by material, what are the lithium batteries?

One is called a lithium metal battery, which generally uses manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and uses a non-aqueous electrolyte solution.
The two are lithium-ion batteries, which generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and use a non-aqueous electrolyte.Usually, the power batteries we talk about most include lithium iron phosphate batteries, lithium manganese oxide batteries, lithium cobalt oxide batteries, and ternary lithium batteries (ternary nickel cobalt manganese). This kind of battery has different uses from polymer lithium batteries, so The price will be higher.
 

According to the materials, there are the following types:

The first type is a steel shell battery, which is the steel used for the shell.

The second type is an aluminum shell battery, similarly the shell is made of aluminum.

The third type is a polymer lithium battery, the outer shell is a polymer material, mostly silver

According to the shape, there are also three categories:

The first type is cylindrical batteries, which are used a lot, such as 18650, 26650, etc., which are generally used in combination, and the ones with fewer combinations can be used as digital products, like early notebook computers, generally 8 18650, mobile power, Combinations ranging from one to five or six.

The second type is square battery. Most of this type is polymer lithium battery. Because this polymer is very malleable, it can be made into many shapes, and its length, width and height can be adjusted at will. Now most digital products use this type of battery. battery.

The third type, abnormal-shaped batteries, are some weird-shaped batteries. According to the needs of the product, the battery should also have a matching shape. For example, the popular smart wearable products, such as smart bracelets, are ring-shaped, so the battery is also made into a ring. Most of the batteries are also made of polymer lithium batteries.

The above is a general classification of batteries. Have you learned it? If you don’t understand, you can contact me. Let’s learn and make progress together. We mainly make polymer lithium batteries.
