Lithium-Ion Battery Working Principle

The lithium-ion batteries for sale are composed of the anode, cathode, diaphragm, electrolyte, and two current collectors (positive and negative electrodes). The anode and cathodes store lithium. The electrolyte brings positively charged battery lithium ions from anode to cathode and vice versa. The motion of lithium ions produces free electrons in the anode and a charge on the positive current collector. The current then flows from the current collector through the supplied device (mobile phone, computer, etc.) to the negative current collector. The partition prevented the electronic flow inside the lithium-ion batteries.

When the lithium-ion battery sale discharges and generates a current, the anode releases lithium ions to the cathode, producing electrons from one end to the other. When the device is inserted, the opposite occurs: the lithium-ion is released by the cathode and received by the anode.

Lithium-Ion Battery Materials

Key raw materials for manufacturing lithium-ion batteries (LIBs) include lithium, graphite, cobalt, and manganese. With increased deployment, commercial lithium-ion battery is making the production of an increasingly important source of demand. These materials are limited resources, and their production is highly concentrated in a few countries. Due to the high geographical concentration of production, most materials on the market are generally less open than traditional materials, such as aluminum and copper.

Lithium-Ion Battery Use

1. Energy storage system

The lithium-ion battery is a better solution in the energy storage system. According to the different installation locations, the application scenario can be divided into the power consumption side, power generation side and power grid side.


Facing the lightweight electric vehicle market, the new non-magnetic soft pack lithium-ion battery design with lightweight power battery has the characteristics of high safety, high performance, low lithium-ion battery cost, strong power, long life and other on.

3. New energy vehicles

For new energy vehicles, industrial lithium-ion batteries are the most critical component, and also one of the hot spots of industrial chain investment in recent years.

4. Consumer electronics

Many lithium-ion battery types were originally used in digital products. After 20 years of development, the application of lithium batteries in consumer electronics has been very mature.

Difference Between Li Ion And Li Polymer Batteries

The biggest difference between lithium-ion and lithium-polymer batteries is the chemical electrolyte between their positive and negative electrodes.A lithium-ion battery uses a liquid electrolyte, while a lithium-polymer battery uses a dry solid, gel-like electrolyte.

Energy Storage Systems (ESS) utilizing lithium-ion (Li-ion) batteries are the primary infrastructure forsolar farms and peak shaving facilities where the electrical grid is overburdened and cannot support the peak demands.In general, Lithium ion batteries (Li-ion) should not be stored for longer periods of time, either uncharged or fully charged. The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. Storage at 5°C to 15°C is optimal.

Types of Lithium Ion Cells

There are mainly 3 types of lithium ion cell: cylindrical, prismatic and pouch cells.Lithium-ion cells are widely used for their high lithium ion cell voltage and high energy density.
