Lithium battery manufacturers talk about the recycling value of lithium batteries. Waste lithium batteries have a high recycling value, used lithium batteries can not only be recycled and sold, and it is a good thing for the country and the people. Lithium batteries have a complex structure and different specifications, and it is more difficult to recycle and reuse. The recycling process of waste lithium batteries is complex, and the materials and formulations of lithium batteries are different from different lithium battery manufacturers.
At present, there are many types of waste lithium batteries, lithium iron phosphate, lithium cobalt acid, lithium manganese acid, lithium cell phone batteries, 18650 type lithium batteries, lithium batteries for electric vehicles and a large number of waste lithium batteries, recycling these waste lithium batteries to be first classified, different types of lithium batteries bring different values.
Lithium battery manufacturers talk about the recycling value of lithium batteries
In recent years, lithium batteries as a new type of energy storage is accepted by people. Now a large number of lithium batteries are used in travel tools and electronic equipment, the recycling of lithium batteries is imminent, Cunningham Electric lithium battery manufacturers attach great importance to lithium battery recycling.
For the use of waste lithium batteries, we know that the cobalt, lithium, copper and plastic in waste lithium batteries are valuable resources with high recycling value. Therefore, the scientific and effective treatment and disposal of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. In order to alleviate the increasingly serious problem of resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to recycle all components of used lithium batteries.
1. The demand for lithium battery power continues to grow
The use of lead-acid batteries as power in low-speed electric vehicles is largely due to the cost advantage of lead-acid batteries, which are relatively mature, stable in performance and safe. However, due to the huge environmental pollution risk of lead-acid batteries and the continuous development of lithium battery technology, as well as the advantages of lithium batteries in terms of capacity and service life, lithium batteries as power will become the development trend of low-speed electric vehicles. It is foreseeable that the maintenance workshop will receive more and more used lithium batteries in the future.
2. Waste lithium batteries have strong recycling value
Anode, cathode, diaphragm, electrolyte and other materials contain a large number of precious metals. Different power lithium battery cathode materials contain different precious metals, among which the most promising metals are cobalt, lithium and nickel. For example, the average content of lithium in ternary batteries is 1.9%, nickel is 12.1% and cobalt is 2.3%. In addition, copper and aluminum also have a high recycling value at 13.3% and 12.7%, respectively. At present, some companies have started to collect lithium batteries for a fee.
3. Improper disposal of used lithium batteries will threaten the environment and health
Although lithium batteries do not contain mercury, cadmium, lead and other toxic heavy metals, they can cause environmental pollution. For example, once the electrode material enters the environment, metal ions in the positive electrode of the battery, negative carbon dust, strong alkali and heavy metal ions in the electrolyte may lead to heavy environmental pollution, including raising the pH value of the soil, if not handled properly and toxic gases may be generated. Therefore, the treatment of waste lithium batteries not only brings economic benefits, but also contributes to environmental protection and sustainable socio-economic development.
Lithium battery recycling methods
There are two main methods of recycling lithium batteries: laddering and dismantling.
The ladder utilization method is commonly referred to as making full use of the residual value of lithium batteries, which are difficult to sustain on a certain ladder and then applied to the next ladder until there is no place to use. Only those batteries that do not have any use value are made into waste batteries. However, this method is currently a concern due to the imperfect recycling system and the lack of uniform standards on when to recycle and to what extent to move to the next ladder.
The second method is disassembly and recycling. The specific methods of disassembly and recycling of waste lithium-ion batteries are divided into three categories: physical, chemical and biological methods. The physical method includes fire, mechanical crushing flotation method, mechanical grinding method, etc.
The development trend of lithium battery recycling market
(1) At this stage, the recycling method of lithium batteries will still be mainly disassembled and recycled, and digital batteries will still be the main body of battery recycling.
(2) After 2020-2022, along with the approach of the final end-of-life of power batteries, the power battery recycling volume will usher in a "peak", and the market recycling volume will account for more than 20%.
(3) With the acceleration of the commercialization of 5G and the massive retirement of lead-acid batteries, the future recycling of power batteries will see rapid growth in the field of secondary utilization, and the market is promising.
Summary: lithium battery recycling value analysis, do you understand clearly? After the gradual influx of waste lithium batteries into the market on the one hand will lead to a waste of resources, on the other hand will cause pollution of the environment, endanger human health, while also endangering the development of future generations. All of these make the recycling of used lithium batteries is of great significance.
