Introduction of 50% Compressed Acetylene Carbon Black Powder
Compress acetylene carbon black powder with helical exhaust, and
make its volume per unit weight mass reach a half of the powder to
gain 50% compressed acetylene carbon black. Compared with acetylene
carbon black powder, 50% compressed acetylene carbon black boasts
smaller volume, is convenient for shipment and saves transportation
Acetylene carbon black has a series of unique and excellent
properties, such as high degree of graphitization and developed
branch structure, so it has excellent electrical conductivity,
strong adsorption and dispersion properties, which makes it become
a significant material in the zinc-manganese batteries, battery
plates, including lead-acid batteries, lithium batteries,
During calcium carbide pyrolysis, the by-gas is decomposed to gain
99% purity refined acetylene which goes through continuous
pyrolysis to gain the acetylene carbon black supplied by our
company. After heating the inner temperature of the reactor to over
800C, the acetylene decomposition initiation temperature, acetylene
is introduced to start thermal decomposition.
Due to the exothermic reaction, the reaction can be carried out
automatically. In order to obtain a stable mass, the reaction
temperature should be maintained at about 1800C. The furnace
temperature can be controlled by the water cooling jacket of the
outer cylinder of the reaction furnace.
Compared with the furnace carbon black, its crystallization and
secondary structure are more developed, so the conductivity and
liquid absorption are also more excellent. Due to few heavy metals
and other impurities, so the loss caused by self-discharge is
little, and storage performance is also better.
Acetylene carbon black structure is high, and can make the electric
core mixture become porous in order to absorb more electrolyte to
reduce the battery internal resistance, and eliminate harmful side
effects caused by impurities. Therefore, the discharge performance
and service life of the battery are enhanced.
Compared with the conductive carbon black by the oil furnace
method, acetylene carbon black can reduce the specific capacity
loss of lithium batteries and the price is cheap.
1.The positive electrode of zinc-manganese dry battery is composed
of manganese dioxide, acetylene carbon black, solid ammonium
chloride and proper electrolyte. Positive electrode active
material, manganese dioxide is semi-conductor, and its conductivity
is poor. The electrode composed of it alone can’t work effectively.
In order to increase the conductivity of the cathode, use acetylene
carbon black as the cathode conductive material, increase the
discharge and prolong the discharge time.
2.Add acetylene black to battery plates (lead-acid batteries,
lithium batteries, lithium-ion batteries, polymer batteries, air
batteries, etc.) so that they can absorb more electrolyte to
improve the ionic conductivity of the electrodes. Improve battery
storage time, and extend its service life.
Tips: Many different materials have been used in order to prevent the
liquid components of the zinc-manganese battery from flowing and to
reduce the internal resistance of the battery, including natural
stone powder and plaster, and the most suitable is acetylene carbon
