F.A.Q.

The lithium ion battery electrode usually include a positive electrode and a negative electrode. The positive electrode is the oxidant in the battery, which is usually composed of lithium-containing metal oxides or multi-compounds; the negative electrode is the reductant in the battery, which is usually composed of carbon materials (such as graphite).

Generally speaking, the manufacturing of battery electrodes refers to the production of positive and negative electrodes, which is the basis of lithium-ion battery manufacturing. It includes mixing, coating, rolling, slitting and cutting in sequence.

During the charge and discharge process of lithium-ion batteries, lithium ions are in a state of motion from positive electrode → negative electrode → positive electrode. This is like a rocking chair, with the two ends of the rocking chair being the battery electrodes, and lithium ions moving back and forth at the two ends of the electrodes.

The structure of lithium-ion batteries mainly consists of two parts: positive and negative electrode plates and a separator. The positive electrode active material is generally lithium manganese oxide or lithium cobalt oxide, while the negative electrode active material is generally graphite.

The positive electrode materials of lithium batteries are generally composed of lithium carbonate, lithium iron phosphate, lithium manganese oxide and nickel-metal hydride batteries; the negative electrode materials are generally composed of nickel-metal hydride battery positive electrodes and nickel-cobalt battery negative electrodes.

Lithium battery electrodes are key factors in determining battery performance. The positive electrode material determines the battery’s energy density, operating voltage, cycle life and other performance, while the negative electrode material affects the battery’s capacity, cycle stability and safety.

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.
