The invention relates to a recycling
separation process of
electrode component materials of used
lithium batteries, which comprises shearing detached
cathode materials of used
lithium batteries into sheets and placing the sheets in a hammer
crusher for stripping carbon
powder and
acetylene black
powder which are attached on the surface of
cathode copper foil by hamming and vibrating, wherein the lower part of the hammer
crusher is provided with a
sieve plate, hammer-crushed
cathode particles having a
diameter smaller than the bore
diameter of the
sieve plate fall into sieving equipment under the
sieve plate through the pores of the sieve plate,
cathode material having a
diameter larger than the bore diameter of the sieve plate is circularly crushed by hammering in the hammer
crusher till the diameter of the
cathode material is smaller than the bore diameter of the sieve plate, and due to the size and shape differences between the particles, the crushed particles which fall into the sieving equipment and are non-
metal carbon power and
acetylene black
powder are separated from
metal copper through vibration sieving after the stripping by hammering and vibrating; and shearing the anodes of used
lithium batteries into sheets and delivering the sheets into drum-type
pyrolysis equipment for
processing, wherein an organic bonder bonding
aluminum foil, lithium cobaltoxide and
acetylene black is decomposed under heat, the battery
anode material of which component materials are stripped mutually is continuously
discharge out from the other end of the
pyrolysis equipment, and thus the separation of the
anode aluminum foil from the lithium cobaltoxide and the acetylene black is realized through vibrating, impacting and sieving in the follow-up sieving equipment with an impacting member. The process has the
advantage of simplicity, high efficiency, easy control, cleanness and
environmental protection.
