Waste ternary lithium battery cathode material recycling equipment

Our company Shaanxi Chengda Industrial Furnace Manufacturing Co., LTD. In the context of the dual carbon goal, with the country vigorously develop new energy vehicles, lithium batteries as a power source of new energy vehicles have been more widely used! . It is predicted that the number of electric vehicles on the road worldwide will reach 253 million by 2030. At the same time, the demand for power lithium-ion batteries will reach 2,800 to 3,000 GW.h, and the life of lithium-ion batteries is 3 to 10 years (1), so in the next 10 years, the number of used lithium batteries will show growth, which will bring new problems and challenges to environmental protection, human health and economic development. Therefore, how to recycle waste lithium batteries as green resources has become a hot topic in the whole society, especially the recycling of positive electrode materials with high added value.

Ternary lithium battery regeneration process
Wet gold leaching regeneration refers to the use of positive leaching liquid as raw material, by adding appropriate reagents to adjust the leaching liquid o and different metal ion concentration ratio to regenerate the synthesis of positive electrode materials, maximize the comprehensive recovery efficiency of metal, to achieve a closed cycle of recovery process. The advantage of wet regeneration is that the separation steps such as extraction, precipitation and so on are avoided after the dry process, which directly realizes the recycling of positive electrode materials. At the same time, the simple and effective process flow makes the wet regeneration has the value of popularization in industrial production. At present, the two most commonly used regeneration methods are co-precipitatin method and sol-gel method.

Waste Ternary Lithium Battery Material Recycling Electric Furnace Equipment

Product Overview

Core Features

1. High-Efficiency Metal Recovery

• Selective Smelting Technology: Utilizes electric arc heating to reach temperatures of 1400-1600℃, enabling the selective reduction of metal oxides (NiO, Co₃O₄, MnO₂, Li₂O) in battery cathode materials. Recovers lithium, nickel, cobalt, and manganese with purity levels exceeding 99.5%.
• Optimized Furnace Design: Features a tilted furnace body for efficient slag-metal separation and tapping. The molten metal phase (nickel-cobalt-manganese alloy) and slag phase (lithium-enriched) are separated and collected separately, maximizing metal recovery rates (up to 95% for nickel, cobalt, and manganese; 85% for lithium).

2. Energy-Saving & Environmental Protection

• Electric Heating Advantages: Adopts high-power electric arc heating, which is more energy-efficient than traditional fossil fuel-fired furnaces. Power consumption is as low as 800-1200 kWh per ton of processed battery materials.
• Low Emission Control: Equipped with a sealed furnace body, flue gas dust removal, and acid gas absorption systems. Effectively captures and treats harmful emissions (dust, SO₂, HF), ensuring compliance with strict environmental standards (e.g., EU GB 18484 and US EPA regulations).

3. Intelligent & Automated Operation

• PLC+AI Control System: Real-time monitors key parameters such as furnace temperature, electrode current/voltage, and feeding rate. AI algorithms optimize smelting conditions to maintain stable operation and consistent metal recovery. Supports remote operation and data logging for process traceability.
• Automatic Feeding & Tapping: Integrates with automatic feeding systems (e.g., screw conveyors) for continuous processing of crushed battery materials. Automated tapping mechanisms ensure safe and efficient collection of molten metals and slag.

4. Durable & Reliable Structure

• High-Temperature Resistant Materials: Furnace lining uses corrosion-resistant refractory materials (e.g., magnesia-chrome bricks) to withstand the harsh smelting environment. Water-cooled furnace walls and electrodes extend equipment lifespan to 3-5 years.
• Safety Interlocks: Incorporates multiple safety features, including over-temperature protection, short-circuit prevention, and emergency shutdown systems, ensuring operator safety and equipment reliability.

5. Flexible & Scalable Configuration

• Customizable Capacity: Available in capacities ranging from 500 kg to 5 tons per batch, suitable for small-scale pilot plants to large-scale recycling facilities.
• Adaptable to Feedstock: Handles various forms of waste ternary lithium battery materials, including crushed cathode powder, whole battery cells (after discharge and dismantling), and production scrap.
