Due to its excellent performance, lithium secondary batteries are widely used in energy batteries. 18650 manufacture With the development of lithium secondary battery technology, it has been widely used in our daily life, and rechargeable batteries for various purposes are becoming increasingly popular. Understand the energy battery industry, fully understand the battery, and then let us do "for my use", the 18650 lithium battery has a certain application in the following areas.

Storage of energy

The main applications are base station power supply, clean energy storage, power grid energy storage, and home optical storage systems.

Classification by power

There are mainly electric urban traffic management tools, electric bicycles, and new energy vehicles included in this category.

The digital age

There are a variety of mobile phones, tablets, laptops, electric toys, MP3/MP4, headphones, charging babies, airplane models, mobile phone power supplies, etc.

The classification of 18650 lithium batteries can be divided into the following categories.

Sort by battery performance first

Power and energy batteries are essential components in plug-in hybrid electric vehicles. Energy batteries have high energy density, allowing for sustained high-energy output, while power batteries have high power density, enabling instantaneous high-power output. Both types of lithium batteries are necessary for a vehicle to have a significant range on pure electric driving and efficient performance in hybrid mode.

Energy type, from a simple analysis and understanding, is similar to a marathon runner. To have endurance, we need high capacity, but the high current through discharge technology performance design requirements are not high; So for the power type is to improve the sprinter, fight is the outbreak, but endurance must also be there, otherwise the capacity is too small to run far.

Depending on the electrolyte material

A lithium-ion battery can be divided into liquid lithium-ion batteries (LiBs) and polymer lithium-ion batteries (PLBS).

A liquid electrolyte (most commonly used in power batteries) is used in liquid lithium-ion batteries. It is possible to replace polymer lithium-ion batteries with solid polymer electrolytes, which can be either dry or colloidal. Polymer gel electrolytes are most common at present. Solid-state batteries are those whose electrodes and electrolytes are solid.

Classification of products based on their appearance

There are three types of packaging: cylindrical, flexible, and square.

Generally, outer packaging is made of steel or aluminum. Flexible packaging uses aluminum-plastic film. Soft bags are also square. Aluminum-plastic film soft bags are commonly called soft bags on the market, while polymer batteries are also called soft bags.

The model number of a cylindrical lithium-ion power battery is usually 5 digits. The first two Chinese numbers are the diameter of the battery, and the middle two student numbers are the height of the battery. The unit is millimeters. A lithium battery with a diameter of 18 mm and a height of 65 mm, for example.

According to the pole material classification, 4

Battery materials: lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide (binary batteries: lithium nickel manganese oxide/lithium nickel cobalt oxide), ternary batteries: lithium nickel cobalt manganese oxide (NCM), lithium nickel cobalt aluminate (NCA).

Materials for anodes: Lithium titanate battery (LTO), graphene battery, carbon nanofiber battery.

In the market, graphene is mainly used in graphene-based batteries, so that graphene paste is applied to the plate or graphene coating is applied to the diaphragm. Lithium, nickel, and magnesium-based batteries are virtually nonexistent.
