Providing high-performance anode materials for lithium ion battery manufacturing

Lithium-ion battery anodes are created from a mixture of carbon or non-carbon materials, binder and additives affixed onto both sides of copper foil, then dried and compressed – an integral component in both charging and discharging processes of lithium batteries. Their main role is to detach lithium ions reversibly whilst at the same time store/release energy efficiently.

Xiaowei offers high-purity lithium battery electrolytes for companies or research and development laboratories who want to enhance the electrochemical performance and safety stability of lithium batteries.

Our lithium ion battery electrolytes are mainly composed of lithium salt main salt, LiPF6, or LiFSI as well as several functional additives which are organic additives most commonly. The lithium batteries you manufacture can be used in various applications from consumer electronic battery products, electric vehicles, to energy storage devices.

Provide a variety of active anode materials:
Xiaowei provides a variety of negative electrode materials including carbon materials such as natural graphite and artificial graphite, and non-carbon materials including silicon-based materials, titanium-based materials, tin-based materials, metallic lithium, etc., to meet your lithium battery manufacturing needs.

Characteristics of high-quality lithium ion anode materials

For the production of high-grade lithium batteries, anode materials must meet certain requirements.
(1) Low voltage when lithium ion is embedded and dislodged, so that the battery has a high operating voltage.

(2) The negative electrode material has high energy density.

(3) Main body structure is stable, and the solid electrolyte interface (SEI) film formed on the surface is stable, so that the battery has good cycling performance;

(4) Small surface area and small irreversible loss, so that the battery has good cycling performance.

(5) Good ionic and electronic conductivity, which helps to reduce polarization, so that the battery has high power characteristics and capacity.

(6) Good safety performance, so that the battery has a high power characteristics and capacity.

(7) the slurry is easy to prepare, the battery has a high charge/discharge efficiency.

(8) Low price and environmentally friendly and other characteristics.

Anode material is one of the key materials for lithium-ion batteries, accounting for about 10% of the cost of lithium batteries


Negative electrode is made of anode active material carbon material or non-carbon material, binder and additives mixed to make a paste-like adhesive uniformly coated on both sides of the copper foil, after drying, rolling and become. The anode material is the main body of lithium-ion battery to store lithium, so that lithium ions are embedded and dislodged in the process of charging and discharging.

Anode materials for lithium-ion batteries are mainly categorized into carbon materials and non-carbon materials.

(1) Carbon anode materials can be specifically categorized into graphite, hard carbon, soft carbon, graphene and other anode materials, of which, graphite materials can be further categorized into natural graphite and artificial graphite;

(2) Non-carbon anode materials include titanium-based materials, silicon-based materials, tin-based materials, nitride and lithium metal.

There is a wide variety of anode materials for lithium-ion batteries, and the most widely marketed and safest material is graphite. Silicon-based anode materials are the most promising to replace graphite as the next generation of high-performance lithium-ion battery anode materials. However, the lithiation of silicon has the inherent disadvantages of large volume expansion (>300%), poor electrical conductivity, and low diffusion coefficient of lithium ions, which makes the silicon-based anode materials have not yet realized large-scale market applications.

Lithium metal has very high theoretical specific capacity and low electrochemical redox potential, the theoretical capacity of lithium metal as anode is as high as 3860mAh/g, which is 10 times higher than that of the commercial graphite anode, and it plays a decisive role in the charging and discharging efficiency and capacity density of lithium battery.
