The purpose of the recovery of lithium-ion battery materials, is the battery-use battery safe? Lithium-ion batteries should be recovered after ending their use cycles, important for environmentalism and economic considerations. The lithium-ion battery usually contains more harmful substances, Ni, Co, and phosphemical ecological toxicity score exceeding 1000, and is considered to be high-risk substances. If the waste lithium ion battery takes ordinary waste treatment methods, the metal and the inorganic, organic compound will cause serious pollution to the atmosphere, water, soil, and have great harmful pollution.

The purpose of recovery of lithium-ion battery materials ● Environmental protection: the positive material of the lithium-ion battery contains nickel, cobalt, manganese, lithium and other heavy metal elements, which cause pollution to the environment, water, etc.; The et al. Will cause dust pollution; in addition, the electrolyte of lithium-ion batteries contains toxic chemical components, which will also cause fluorofluidity.

● Resource saving: A large number of metal elements, nickel, graphite, etc. in the lithium-ion battery, but the metal elements like cobalt are scarce; my country's lithium elements are a lot, but the unhading is relatively large, generally Distributed in Tibet, Qinghai, Sichuan, etc. ● Advantage: The ladder utilization and resource recovery of lithium ion batteries can still be commercialized, because in recent years, the automotive industry has transferred to electricization, and the demand for lithium-ion batteries has increased, which leads to very expensive prices.

High, metal cobalt price is 600,000 / ton, nickel 100,000 / ton, carbonate 1.70,000 / ton, metal lithium 900,000 / ton. Is the battery that use the battery safe? Retired battery ladder uses an end to see the life of retired batteries, and second to see the safety of the ladder utilization process.

At present, a large number of lithium-ion batteries use an organic solvent system, which occurs heat out of control, causing a chain reaction, which needs to be highly valued. Therefore, the ladder of different states should be used to clarify its safe operation boundary conditions under different storage conditions, and the safety warning strategy during operation is developed, and the recession characteristics under different conditions are ensured. Under the premise of safe use, the maximum residual value of the battery is used.

The degree of reaction is also reduced due to the decrease in its own energy after the ladder battery heat is out of control. Due to the change in the internal state of the battery, the starting temperature of the self-production temperature and the thermal loss of control is getting lower and lower, and it may be small after the ladder battery is small, but related batteries, if the same application may be more easier, so still According to the actual situation of the ladder battery, its security strategy is made, and finally select a suitable fire extinguishing mode. The power lithium battery is the basis of the ladder, the quality of the power lithium battery directly affects the safety of the ladder.

In particular, the ladder uses the energy storage project, which is connected in parallel with thousands of monomers, and once there is a safety accident, the chain effect may cause a large area of ​​loss, and the entire energy storage project is fatal. As a result, the industry experts suggest the first batch of retired dynamic lithium batteries with materials recovery, not to use business applications, prevent safety accidents. The development of the ladder is based on environmental benefits and economic benefits, but don't forget "safety" is the fundamental of its development.

Power lithium battery-related companies must strengthen the quality of powerful lithium batteries, reduce the safety hazards existing in each link; the relevant government departments should also pay attention to the safety of power lithium battery, gradually improved in relevant policies and regulations, cautiously promote power lithium batteries Tradder use, promote the healthy and orderly development of new energy automotive industries. In general, the waste lithium-ion battery environment is harmful but the recovery value is high, and the metal elements are more scarce, imported relying on high metal resources. In order to ensure a positive impact, a complete recycling system must be constructed to safely handle and recover the discarded lithium-ion battery, and re-integrate recycled battery materials into a lithium-ion battery supply chain, promoting a broader economic development, while Prevent environmental and security have a negative impact.

In the next twenty years, the global number of lithium-ion batteries will rise steadily, which highlights these batteries must have sustainable recycling paths. Battery recycling is to use its innovative solution to address emerging challenges, so improved technology and innovative supply chains to recycle batteries and meet the rapid rise of key and scarce battery materials. Lithium-ion battery has become a key driving force, scalability, low cost, safety and environmental sustainability of carbon-based economy to sustainable energy transformation, is the core principle of lithium-ion battery recovery technology, and will reduce greenhouse gas emissions.
