1. Battery: Acetylene carbon black has good conductivity and is widely used in battery manufacturing.

2. Lead-acid batteries, lithium batteries, and lithium-ion batteries. Acetylene black has a medium particle size, a very high structure, and low ash and volatile content, so its resistivity is extremely low. Acetylene carbon black special for storage battery can improve the storage time of storage battery and prolong its service life. Conductive carbon black (35-40nm) which pyrolyzes acetylene at high temperatures usually refers to acetylene made from calcium carbide. The purified acetylene gas is thermally cracked at high temperature without air, and then cooled and collected to obtain high-performance carbon black, commonly known as acetylene black (ACET). Acetylene carbon black can be regarded as a superconducting carbon black. Compared with oil furnace conductive carbon black, acetylene carbon black can reduce the loss of specific capacity of lithium batteries.

3. Conductive and antistatic rubber, silica gel, plastic and cable shielding materials. Conductive carbon black, as a functional and highly conductive filler, is mainly used in conductive and antistatic coatings, plastics, rubber, adhesives, ink, battery materials, cable shielding materials, and so on. Widely used in various industrial sectors such as electronics, electromechanical, communication, printing, aerospace, weapons, and so on.

4. Special tires and capsules for tires. Acetylene carbon black can be used in tires to reinforce and conduct heat. The vulcanizate reinforced with acetylene carbon black has high tensile strength, hardness, and good physical properties.

5. electromagnetic wave insulation and gas dispersion electrodes, catalyst materials, microwave absorption materials. Microwave-absorbing materials are mainly composed of absorbing agents and matrix materials. According to the working principle of absorbing materials, the absorbing ability of absorbing materials is closely related to the absorbing ability of absorbent. Acetylene carbon black is an inorganic wave-absorbing material with electrical loss, which has a good wave-absorbing function.
