Recycling and reuse of waste lithium batteries

With the rapid development of new energy vehicles, the green recycling of waste lithium-ion batteries has become a global concern. As a deep cultivator in the field of mining equipment and resource recycling, Henan Zhengzhou Mining Machinery Co., Ltd. has seized the opportunities of "carbon neutrality" and the development of the circular economy, and has innovatively created a complete set of "safe-effective-environmentally friendly" lithium battery recycling and utilization technology systems, which are gradually moving towards industrialization and setting a new benchmark for the industry.

Technical breakthrough | Open up the whole link from disassembly to high-value recycling

The lithium battery recycling production line built by ZK CORP has built a complete closed-loop process flow around the three core links of "safe treatment, effective purification, and intelligent sorting":

Safe and harmless disassembly:

The dual process of physical discharge + chemical neutralization is used to control the residual voltage of the battery cell below 0.5V, reducing the risk to a certain extent; at the same time, the inert atmosphere crushing technology is introduced to effectively inhibit the volatilization of the electrolyte and ensure the safety and stability of the entire processing process.

High temperature cracking + intelligent purification:

At 600-800℃, high-temperature oxygen-free cracking effectively decomposes the organic components in the battery, with a cracking rate of over 98%. The tail gas treatment adopts a two-stage purification scheme to ensure that VOC emissions are significantly better than national standards.

Full-dimensional intelligent sorting system:

Integrating screening, magnetic separation, wind separation, and specific gravity separation, the separation purity of black powder, copper, and aluminum is as high as 99.5% or more, and the recovery rate of copper and aluminum exceeds 97%, realizing resource utilization.

High-purity black powder purification process:

Adopting the coupling technology of hydrometallurgy and pyrometallurgy roasting, the purity of recovered cobalt, nickel, and manganese reaches 99.8%, and the lithium recovery rate exceeds 85%, which fully meets the raw material requirements of high-end positive electrode materials.

Industrial advantages | Modularization, low energy consumption, high returns

The technical team of ZK CORP focuses on the dual optimization of production efficiency and environmental protection costs, and successfully developed a modular production line with a single-line processing capacity of 500kg/h, an efficiency increase of 40%; the energy self-circulation system can effectively recycle pyrolysis waste heat, and the energy consumption per ton of material is reduced by 30%.image003.jpg

Application scenarios | Multi-system compatibility, broad market prospects

This technical system is compatible with a variety of mainstream battery types, such as ternary lithium and lithium iron phosphate, and is suitable for different structures, such as soft packs, cylinders, and squares. It has good industrial adaptability and market development capabilities.

Leading the future | ZK solutions, enabling green circulation

From laboratory research and development to industrialization, ZK CORP has always insisted on being driven by scientific and technological innovation, and creating an "effective, safe, and clean" closed-loop system around the entire chain of lithium battery recycling. By continuously optimizing equipment performance and improving process technology, the company is pushing China's lithium battery recycling industry into a new era with its technical strength and market insight.
