18650 Battery Recycling; theoretical lifespan is 1000 cycles of charging. Due to its high energy density, it is predominantly used in laptop batteries. Additionally, the 18650's excellent stability during operation makes it widely used in various electronic fields: commonly used in portable power supplies, wireless data transmitters, electric heating garments and shoes, portable instruments and meters, portable lighting equipment, portable printers, industrial instruments, and other devices.
Cylindrical cells offer excellent capacity, high output voltage, and superior charge-discharge cycle performance. They provide stable output voltage, can discharge at high currents, have high stability, a wide operating temperature range for safe use, and are environmentally friendly.
It is understood that waste 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, with a high demand, and can only import it. Recycling lithium-ion batteries can effectively alleviate this situation. Data shows that if waste lithium-ion batteries are fully recycled, 240 tons of cobalt can be recovered annually, which alone is worth over 40 million. Similarly, waste nickel-hydrogen batteries contain up to 30%-50% nickel, about 2%-5% cobalt, and 5%-10% rare earth elements, also with significant recycling value.
Used automotive power lithium batteries are reprocessed for secondary use after passing quality inspections, which include cell sorting and grading with safety assessments and cycle life tests. Only after sorting, grading, and reassembly can the cells be reused.
Cylindrical batteries offer consistent individual performance, high production capacity, and are suitable for mass production. They have excellent temperature resistance, are safe and unlikely to explode, and have a wide range of applications. They effectively and durably enhance polymer performance, making production and installation convenient.
The technology for the recycling and utilization of power lithium batteries still needs to break through. Currently, to balance energy consumption and water pollution issues, companies primarily adopt a "dry and wet combined" method to dismantle lithium batteries and recycle precious metals like cobalt and nickel. While recycling lithium carbonate can address the potential shortage of lithium resources in the future, there has not been a substantial breakthrough in the research of recycling lithium carbonate on a global scale. The cost of recycling lithium carbonate from lithium batteries is still more than 5 times the direct production cost for the company.
Currently, the field of lithium battery recycling and utilization is mainly divided into two aspects: 1) the graded use of batteries that meet the degree of energy attenuation (such as for energy storage or low-speed electric vehicle fields), including lithium iron phosphate batteries and ternary material batteries; 2) the disassembly of batteries that cannot be graded used, to recover materials such as nickel, cobalt, manganese, and lithium, such as digital batteries and some ternary material batteries. According to GGII research, in 2018, the total amount of power battery recycling was 10.93 million tons, with 2,460 tons used for graded use, indicating that the scale of graded use in the battery recycling field, especially in the power battery recycling field, is much smaller than the scale of recycling and disassembly.
Battery Recycling & Reuse Policies: Both domestically and internationally, regulations regarding the recycling and reuse of power batteries lack legal constraints for their tiered utilization, but there are specific legal provisions for the recycling of waste batteries. EU regulations concerning battery recycling include the Battery Directive, Waste Electrical and Electronic Equipment (WEEE) Directive, and End-of-Life Vehicle (ELV) Directive. The U.S. regulates the production, collection, transportation, and storage of waste rechargeable batteries through federal, state, and local laws. Japan mandates the establishment of recycling systems in the battery industry for the collection and recycling of rechargeable batteries.
Cylindrical cells offer high capacity and voltage output, with robust battery casings that withstand high pressure. They do not swell during use or transport. The design is flexible, featuring excellent charge-discharge cycling performance, stable voltage output, and a wide operating temperature range that is environmentally friendly.
Lithium-ion batteries feature high working voltage, high energy density, long cycle life, excellent safety performance, and clean, non-polluting characteristics, and are widely used in transportation, power, mobile communications, new energy storage, and other important fields. With the popularity and promotion of new energy vehicles, lithium-ion batteries have shone brightly in the energy storage field of new energy vehicles. Due to the high energy consumption and short service life of power lithium-ion batteries, the amount of报废 has surged, causing serious environmental pollution. Additionally,废旧power lithium-ion batteries contain a large amount of resources such as copper, aluminum, and graphite. Without effective recycling, it also leads to resource waste. Therefore, the recycling of used power lithium-ion batteries is urgent.
Cylindrical cell units have excellent mechanical properties, mature production processes, and high efficiency. They offer excellent bending strength, ease of use, simplicity, and effective heat dissipation. They are not prone to combustion or explosion due to improper operations such as overcharging, over-discharging, or short-circuiting.
