LR1130 battery

　　What are the technologies for LR1130 battery recycling?

　　What are the technical means for recycling lithium batteries?

　　There are two typical follow-up paths for LR1130 battery recycling, echelon utilization or direct material recycling.

　　1. Ladder utilization and raw material recycling

　　Retired power lithium batteries are reused in a tiered manner, with materials recycled after tiered utilization; direct material recycling is done in batches that are too small, have no history to check, or fail safety monitoring, etc.

　　The pursuit of economic benefits is the driving force for corporate and social behavior. It stands to reason that through step-by-step utilization, until the usable value of the LR1130 battery is reduced below the maintenance cost, and then raw materials are recycled, the value of the battery can be maximized. But the actual situation is that the traceability of early power batteries is poor, and the quality and models are uneven. The risk of secondary utilization of early-stage batteries is high, and the cost of eliminating risks is high. Therefore, it can be said that in the early stages of power battery recycling, the destination of batteries is most likely to be raw material recycling.

　　2. Extraction method of valuable metals from cathode materials

　　The current recycling of power lithium batteries does not actually achieve the comprehensive recycling and reuse of all types of materials on the entire battery. The types of cathode materials mainly include: lithium cobalt oxide, lithium manganate, ternary lithium, lithium iron phosphate, etc.

　　3. Hydrometallurgy

　　Hydrometallurgy is a method that uses appropriate chemical reagents to selectively dissolve the cathode materials in used lithium-ion batteries and separate the metal elements in the leachate. The hydrometallurgical process is more suitable for recycling waste lithium batteries with a relatively single chemical composition. It can be used alone or in combination with high-temperature metallurgy. It has low equipment requirements and low processing costs. It is a very mature processing method and is suitable for small and medium-sized enterprises. Large-scale recycling of used lithium-ion batteries.

　　Current status of LR1130 battery recycling

　　At this stage, my country's waste LR1130 battery recycling system is not yet complete, and recycling technology and business models have not yet reached mature standards. At present, problems such as immature utilization technology, imperfect acquisition network, imperfect management measures, and inadequate support policies are still plaguing my country's LR1130 battery recycling industry, and the business model and profit model have yet to be explored.

　　The imperfect system of secondary utilization is still the biggest problem currently facing the recycling field of used lithium batteries. There is currently no clear standard for the extent to which the battery capacity can be used in the next step, and the level at which it cannot be used in the next step and needs to enter the recycling process.

　　Currently, there are only a handful of high-quality lithium iron phosphate batteries that can be used in early stage power batteries, and the rest of the batteries, including ternary batteries, are of no use value. After being used for a period of time, it is difficult for ternary lithium batteries to ensure the uniformity of the electrochemical properties of the materials inside the battery, so there are safety risks when used in echelon applications. If the battery pack is disassembled, the cost will be greatly increased. It is valuable only if the battery pack is directly applied without disassembling the battery pack.
