Due to the 18650 battery's lifespan, which theoretically allows for 1000 charging cycles, its high unit density capacity, and excellent stability during operation, it is widely used in laptops, portable power banks, thermal clothing, portable instruments, lighting equipment, industrial instruments, and even portable printers. Owing to its versatility, the 18650 battery recycling market is extremely large.
Reconditioned automotive lithium-ion batteries undergo quality inspections during the process of tiered utilization. This includes cell sorting and grading, which involves safety assessments and cycle life tests. The cells are then sorted and graded, and reassembled before they can be reused.
Currently, the field of lithium battery recycling and utilization is mainly divided into two aspects: 1) The graded utilization of batteries that meet the degree of energy attenuation (used in energy storage or low-speed electric vehicle fields), such as lithium iron phosphate batteries and ternary material batteries; 2) The disassembly of batteries that cannot be graded utilized, recycling materials such as nickel, cobalt, manganese, and lithium, such as digital batteries and some ternary material batteries. GGII research shows that in 2018, the total amount of power battery recycling was 2460 tons for graded utilization, and the total amount of batteries recycled and disassembled was 109.3 thousand tons. In the battery recycling field, especially in the power battery recycling field, the scale of graded utilization is far smaller than the scale of recycling and disassembly.

It is user-friendly, simple, and has good heat dissipation. It will not cause combustion or explosion due to improper operations such as overcharging, overdischarging, or short-circuiting.
The technology for recycling and utilizing lithium-ion batteries still awaits a breakthrough. Currently, companies mainly adopt a "dry and wet combined" method to dismantle lithium-ion batteries and recover precious metals like cobalt and nickel to address energy consumption and water pollution issues. Although recycling lithium carbonate can address the future shortage of lithium resources, there has been no substantial breakthrough in the research on recycling lithium carbonate domestically and internationally. The cost of recovering lithium carbonate from lithium-ion batteries remains more than 5 times the direct production cost for companies.
It is understood that spent lithium-ion batteries have a high recycling value. For instance, common cobalt acid lithium batteries contain metals such as cobalt, copper, aluminum, and iron, with cobalt accounting for about 15%. China is deficient in cobalt resources and has a high demand, necessitating imports from abroad. Recycling lithium-ion batteries can effectively alleviate this situation. Data shows that if spent lithium-ion batteries are fully recycled, 240 tons of cobalt can be recovered annually, which is worth over 40 million. Similarly, spent nickel-hydrogen batteries contain up to 30%~50% nickel, about 2%~5% cobalt, and 5%~10% rare earth elements, all of which have significant recycling potential.
Cylindrical battery cells offer good individual consistency, high production capacity, and can be mass-produced in large quantities. The batteries have excellent temperature resistance and are safe, less prone to explosion. Their usage range is broad, effectively and durably enhancing polymer aggregation performance, and are convenient for production and installation.
Battery Recycling & Utilization Regulations: Current Status - Domestic and international regulations for the recycling and utilization of power batteries lack legal constraints for the secondary use of power batteries, but there are relevant legal provisions for the recycling of waste batteries. - In the EU, the main regulations involving battery recycling include the Battery Directive, Regulations on the Management of Hazardous Substances, and Regulations on the Recycling of End-of-Life Vehicles. - The U.S. employs federal, state, and local regulations to govern the production, collection, transportation, storage, and other processes of waste rechargeable batteries. - Japan requires the battery industry to establish a recycling system for collecting and recycling rechargeable batteries.
Cylindrical cells have low internal resistance, reducing battery self-discharge and extending battery life. Polymers with high discharge currents are ideal choices, boasting superior low-temperature characteristics, excellent energy and power density ratios, a wide range of applications, and compatibility with various instruments and equipment.
