The growing popularity of electric vehicles (EVs) presents us with new challenges related to Recycling of electric batteries. As more and more electric cars appear on our roads, there is a growing need for efficient management of used batteries.
Electric batteries contain valuable raw materials such as:
● Bed
● Cobalt
● Nickel
● Manganese
Improper disposal of these components poses a serious threat to the environment. Toxic substances can enter the soil and groundwater, causing long-term ecological damage.
Recycling of electric batteries It is not just a matter of environmental protection - it is also a strategic economic action. Recovering valuable materials from used batteries allows you to:
● Reduce dependence on the extraction of primary raw materials
● Reduce the production cost of new batteries
● Create new jobs in the recycling sector
In this article, we will take a detailed look at the recycling processes of electric batteries, learn about the technologies used and the challenges facing this dynamically developing industry. We will also present the development prospects and innovations that are shaping the future of EV battery recycling.
Electric batteries are advanced devices that store electricity in the form of chemical energy. There are several main types of batteries on the market:
● Lithium-ion batteries (Li-ion) - the most popular type in electric vehicles
● Nickel Metal Hydride (NiMH) Batteries - used in older hybrid models
● Lead-acid batteries - used in traditional boot systems
● Lithium Iron Phosphate (LFP) Batteries - increasingly used in cheaper EV models
Features of lithium-ion batteries:
● High energy density (150-260 Wh/kg)
● Low memory effect
● Fast charging
● Stable performance over a wide temperature range
Lithium-ion batteries are used in:
1. Electric cars
2. Energy storage
3. Portable devices
4. Emergency power systems
Lifespan and reusability
Modern lithium-ion batteries are characterized by a service life of 8-20 years depending on the conditions of use. After the capacity drops below 70-80% of the original value, EV batteries can be used in stationary applications:
● Energy storage for photovoltaic installations
● Emergency power systems
● Stabilization of the power grid
● Charging station power
A properly operated lithium-ion battery retains about 80% of its initial capacity.
Improper management of used electric batteries carries serious risks to the environment. Batteries stored in landfills release toxic substances into the soil and groundwater, leading to:
● Contamination of aquatic ecosystems
● Soil degradation
● Health risks to local communities
● Emissions of harmful compounds into the atmosphere
Economic value of recovered materials is a key argument for the development of recycling technologies. From one electric battery you can recover:
● Up to 35 kg cobalt
● About 20kg lithium
● Significant amounts of nickel and copper
● Rare earth elements
The prices of these raw materials on the world markets are constantly rising, making recycling an increasingly profitable venture.
The European Union is introducing strict regulations on the content of recycled materials in new batteries:
● 16% recovered cobalt
● 85% Lead
● 6% lithium and nickel
These legal requirements are aimed at:
● Reducing dependence on the import of raw materials
● Development of the European recycling industry
● Creation of new jobs in the circular economy
Recycling of electric batteries contributes to the reduction of the carbon footprint. The production of new batteries from recycled materials requires much less energy than the extraction and processing of primary raw materials. It is estimated that each ton of materials recovered from batteries saves about 1.5 tons of carbon dioxide emitted during the production of traditional batteries.
The recycling process of electric batteries is based on two main methods: Pyrometallurgical and Hydrometallurgical. Each of them offers unique opportunities to recover valuable materials.
Pyrometallurgical recycling
The pyrometallurgical method uses high temperatures to process spent batteries:
● The process begins with the fragmentation of the battery under controlled conditions
● The material is heated to 1200-1500°C
● At high temperature, electrolyte evaporation occurs
● Metals form an alloy that is then separated
● Recovery Effectiveness:
○ Cobalt:up to 93%
○ Nickel:up to 90%
○ Copper:up to 95%
Hydrometallurgical recycling
The hydrometallurgical method is based on chemical processes in an aqueous environment:
● Batteries are pre-sorted and shredded
● The active material is leached in acidic or alkaline solutions
● Selective extraction of individual metals occurs
● The process ends with crystallization or electrolysis
● Recovery Effectiveness:
○ Lit:up to 98%
○ Cobalt:up to 96%
○ Manganese: up to 97%
The choice of recycling method depends on:
1. Battery type
2. Available infrastructure
3. Environmental requirements
4. Operating Costs
5. Expected purity of recovered materials
Modern recycling plants often combine both methods to create hybrid processing processes.
European recycling plants introduce breakthrough solutions in the field of electric battery processing. The largest facility of this type in Europe is located in Żarki (Poland), processing 27 thousand tons of batteries annually.

The recycling of electric batteries faces a number of complex logistical and organizational challenges. Transporting used batteries requires specialized safety procedures due to the risk of fire and chemical leakage. Each battery must be properly secured, which generates additional costs and requires specialized equipment.
The main logistical problems:
● No standard battery disassembly procedures
● High cost of specialized transport
● Limited number of collection points
● Variety of battery types and sizes
Effective recycling requires strict industry cooperation between different entities. Electric vehicle manufacturers need constant communication with recycling companies in order to adapt the design of batteries to their ability to be recycled later.
Key aspects of intersectoral cooperation:
1. Exchange of technical information on battery composition
2. Joint planning of disassembly processes
3. Coordination of collection systems
4. Standardization of markings and documentation
The lack of adequate recycling infrastructure in many regions is an additional challenge. Processing plants need to be strategically placed to minimize transport distances. This requires significant investment in the development of a network of collection points and processing plants.
The safety of workers who dismantle and process batteries is a separate area of challenge. Continuous training of personnel and the implementation of strict safety protocols are necessary to minimize the risk of accidents related to the handling of hazardous materials.
Forecasts indicate an unprecedented increase in the number of used electric batteries in the coming years. By 2030 it is expected 12.85 million tons EV batteries requiring disposal - this is an amount comparable to the weight of 1000 high-rise buildings.
