The anode electrode of lithium ion battery is made of anode electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled. The cathode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process. The current lithium-ion battery anode materials have developed from a single artificial graphite to natural graphite, mesocarbon microspheres, artificial graphite, soft carbon/hard carbon, amorphous carbon, lithium titanate, silicon carbon alloy and other negative electrodes material coexistence. Negative material: graphite is mostly used. New research finds that titanates may be a better material. Negative reaction: lithium ions are inserted during charging, and lithium ions are de-inserted during discharge. When charging: xLi++ xe-+ 6C → LixC6 When discharging: LixC6 → xLi++ xe-+ 6C. Lithium-ion battery anode materials are roughly divided into six types: carbon anode materials, alloy anode materials, tin-based anode materials, lithium-containing transition metal nitride anode materials, nanoscale materials, and nanoscale anode materials. The first is carbon anode material: the battery anode materials actually used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc. The second is tin-based negative electrode material: tin-based negative electrode material can be divided into two kinds of tin oxide and tin-based composite oxide. Oxides refer to oxides of metal tin in various valence states. The third is the lithium-containing transition metal nitride anode material. The fourth is alloy-based negative electrode materials: including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys. The fifth is nanoscale anode materials: carbon nanotube and nanoalloy materials.

Today, our lithium battery current collector materials are packaged and shipped to India, mainly in the following categories:Aluminum foil；Copper foil；Nickel foam；’Carbon cloth；Carbon coated aluminum foil , etc. The current collector is one of the indispensable components in the lithium-ion battery. It can not only carry the active material, but also collect and output the current generated by the electrode active material, which is beneficial to reduce the internal resistance of the lithium-ion battery and improve the battery's performance. Coulombic efficiency, cycling stability and rate capability. We are AOTELEC, we not only provide battery materials, but also battery equipment, please contact me if you need.

The electrolyte is an ionic conductor that conducts conduction between the positive and negative electrodes of the battery. During the charging and discharging process, lithium ions are transported back and forth between the positive and negative electrodes. The infiltration of the electrode piece by the electrolyte involves the three-phase contact of solid, liquid and gas.When the electrolyte is injected into the battery case, the air in the case should be discharged from the electrolyte first, and then the electrolyte will adhere to the surface of the positive and negative active materials. Some electrolytes will enter between the positive electrode-separator-negative electrode through the separator of the winding core.With the continuation of time, there will be the phenomenon that the electrolyte infiltrates the pole piece and the electrolyte in the diaphragm reversely infiltrates the pole piece. When the standing time is long to a certain extent, under the action of surface tension, the infiltration of the pole piece reaches a balanced state. How to improve the wettability of electrolyte: (1) Improve the liquid injection process (2) Improve the core winding process (3) Add electrolyte wetting agent
