Waste Lithium-ion battery breaking and separation recycling system
The waste lithium-ion battery are mainly from the electrical
vehicles, like the two wheels or the four wheels. The lithium
battery generally has two types LiFePO4 as the anode and
LiNi0.3Co0.3Mn0.3O2.
Our machine can process the lithium-ion LiFePO4 as the anode and
LiNi0.3Co0.3Mn0.3O2. battery. The layout like the below:
- To break the batteries pack to separate and check the core is
qualified or not. The battery pack will dispatch the shell,
elements, aluminum and copper.
- The unqualified electric core will be crushed and separated. The
crsher will be in the air device protection. The raw material will
be anaerobic thermolysis. There will be a waste gas burner to make
the exhausted air reach the discharged standard.
- The next steps is to separate with the air blow or the water power
to separate the cathode and anode powder and the copper and
aluminum and the pile head, and the shell scraps.
Waste lithium-ion battery pack breaking lines adopts manual work
and high level of automation.
After breaking, crushing, separation and other continuous process,
we could get the diaphragm, shell, copper foil, aluminum foil,
anode & cathode powder and other products.
The process is based on market demand, resource regeneration and
benefit maximization. Fully efficient recovery of single lithium
batteries, leftover bits of materials can be achieved.
The all discharge is standard after the waste water and off-gas are
treated.
The ecnomical output data:
| NO | Main products | Capacity or yield (%) | Recycling rate(%) |
| 1 | Cathode and anode | 47.47 | >97-98.5 |
| 2 | Copper | 11.76 | >98 |
| 3 | Aluminum | 3.91 | >98 |
| 4 | Electrolyte organic solvent | 12.73 | >97 |
| 5 | diaphragm | 5.92 | >84.5 |
| 6 | Plastic | 4.01 | >98 |
| 7 | Pile head and iron shell | 12.03 | >98 |
The technical parameter and consumption of the lithium-ion battery

Features:
- With on-line oxygen content and temperature inspection, visual
monitoring, PLC and charger etc, it intergrate the centrol
interlock control. It reaches the CT4 explosion-proof. It is with
high safty protection.
- As it is with electricity to crush, it can process the LiFePO4 as
the anode and LiNi0.3Co0.3Mn0.3O2 battery and other types batteries
with high compatibility. Apart from it, its structure shear tooth
can process large capacity. Further more the final scraps are loose
and become flakes which are easy to recycle. Finally the crusher is
safe and solve the salt water long discharge time and water
polution.
- The high yield of the cathod and anode powder. After the
thermolysis and water power separation, the yield of cathod and
anode power is about >98%(quality >98%), while the air blow
separarion reaches 97%(quality >97%). The cathod powder aluminum
content is <0.35%.
- The high yield recycling of the copper and aluminum. After the
color sorter and photoelectric detection and sorting, the final
quality of the copper and aluminum is about >99%.
- Environmental protection. The raw material in and out the machine
is airtight. Also it is with anaerobic thermolysis, air and dust
collecting system. We will strictly control the electrolyte and
discharge. The air burner and purification use the specific
technology wet defluorination. The execution HJ1186-2021 discharge
standard.
