Creating a New Benchmark for Lithium Battery Recycling

Recycling and Reusing of Used Lithium Batteries

With the rapid development of new energy vehicles, the green recycling of used lithium batteries has become a global focus. As a company deeply engaged in the fields of mining equipment and resource reuse, Henan Zhengkuang Machinery Co., Ltd. has seized the development opportunities brought by "carbon neutrality" and the circular economy. It has innovatively created a complete set of lithium battery recycling and utilization technology system integrating "safety - effectiveness - environmental protection", which is gradually being implemented industrially and setting a new benchmark for the industry.

Technological Breakthroughs | Establishing a Full-Link Process from Disassembly to High-Value Recycling

The lithium battery recycling production line created by Zhengkuang Machinery focuses on three core links: "safe processing, effective purification, and intelligent sorting", and constructs a complete closed-loop process:

Safe and Harmless Disassembly

A dual process of physical discharge and chemical neutralization is adopted to control the residual voltage of the battery cells below 0.5V, minimizing risks to the greatest extent. Meanwhile, an inert atmosphere crushing technology is introduced to effectively suppress the volatilization of the electrolyte, ensuring the safety and stability of the entire processing process.

High-Temperature Pyrolysis + Intelligent Purification

High-temperature pyrolysis is carried out in an oxygen-free environment at 600 - 800°C, enabling the effective decomposition of the organic components in the batteries with a pyrolysis rate exceeding 98%. A two-stage purification scheme is applied for tail gas treatment, ensuring that the VOCs emissions are far better than the national standards.

All-Dimensional Intelligent Sorting System

Combining screening, magnetic separation, air separation, and specific gravity separation, the separation purity of black powder from copper and aluminum reaches over 99.5%, and the recovery rate of copper and aluminum exceeds 97%, achieving the optimal utilization of resources.

High-Purity Black Powder Purification Process

A coupled technology of hydrometallurgy and pyro-roasting is used. The purity of recovered cobalt, nickel, and manganese reaches 99.8%, and the lithium recovery rate exceeds 85%, fully meeting the raw material requirements for high-end cathode materials.

Industrial Advantages | Modularization, Low Energy Consumption, and High Returns

The technical team of Zhengkuang Machinery has focused on optimizing both production efficiency and environmental protection costs, successfully developing a modular production line. The single-line processing capacity reaches 500 kg/h, with a 40% increase in efficiency. The energy self-circulation system can effectively recover the waste heat from pyrolysis, reducing the energy consumption per ton of materials by 30%.

At the same time, through the reuse of waste electrolytes and tail gases, resource closure and carbon emission reduction are effectively achieved, meeting both economic benefits and environmental protection indicators.

Application Scenarios | Compatibility with Multiple Systems and Broad Market Prospects

This technology system is compatible with various mainstream battery types, such as ternary lithium and lithium iron phosphate, and is suitable for different structures, including pouch, cylindrical, and prismatic batteries. It has good industrial adaptability and market expansion capabilities.
