With the rapid development of new energy vehicles and energy storage industries, the consumption of lithium batteries has increased sharply, making the recycling of waste lithium batteries an increasingly prominent issue. As a key component of lithium batteries, negative plates are mainly composed of graphite, along with copper, aluminum and other metals. Their recycling and utilization are of great significance for resource recycling and environmental protection.
Physical separation technologies for waste lithium batteries can effectively avoid environmental pollution caused by improper disposal. Random discarding of chemical substances inside waste batteries will severely contaminate soil and water sources and damage the ecological environment. Rational recycling can eliminate such environmental hazards. The industry integrates innovative technologies including automatic dismantling and sorting and direct regeneration of battery materials.
In terms of resource utilization, dry mechanical crushing and separation technology is widely adopted to crush and sort waste lithium battery raw materials efficiently. This process realizes the separation of various metal elements in waste lithium batteries, so as to achieve resource recovery and reuse.
The recycling of waste lithium battery negative plates can not only reduce resource waste and environmental pollution, but also cut down battery production costs and boost the development of circular economy. In the future, with the optimization of physical sorting technology, breakthroughs in direct regeneration technology and strengthened policy support, the recycling of negative electrode materials will develop towards higher efficiency, environmental friendliness and higher added value, providing strong support for the sustainable development of the new energy industry. Scientific recycling of lithium battery negative plates meets environmental protection requirements and serves the national resource strategy.
