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.

Our Waste Ternary Lithium Battery Material Recycling Electric Furnace is a specialized thermal processing system designed for the
environmentally friendly and efficient recycling of valuable metals
(lithium, nickel, cobalt, manganese) from spent ternary lithium-ion
batteries. By integrating advanced electric heating technology,
precise temperature control, and eco-friendly process design, this
equipment enables the recovery of high-purity metals while
minimizing energy consumption and environmental impact. It is a
core component of sustainable battery recycling lines, catering to
the growing demand for circular economy solutions in the 新能源 (new
energy) industry.
- 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).
- 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).
- 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.
- 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.
- 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.
- Waste Ternary Lithium Battery Recycling: Recovers valuable metals from spent electric vehicle (EV)
batteries, consumer electronics batteries, and industrial battery
waste.
- Battery Production Scrap Treatment: Processes defective batteries and production waste generated
during battery manufacturing.
- Secondary Resource Utilization: Converts battery waste into high-purity metals for reuse in new
battery production, reducing reliance on virgin mineral resources.
- Expertise in Battery Recycling: Over 10 years of experience in developing thermal processing
equipment for battery material recycling, with a deep understanding
of the unique challenges of ternary lithium battery waste.
- Customized Solutions: Tailor-made equipment designs based on specific feedstock
characteristics, production scale, and recovery goals.
- Comprehensive Support: Provides end-to-end services, including equipment installation,
commissioning, operator training, and after-sales maintenance.
- Proven Track Record: Successfully deployed in battery recycling plants across China,
Europe, and North America, with a reputation for high performance
and reliability.
