Ni-MH battery pack recycling standards/techniques/models need to be improved

　　At present, used batteries are like useless to vehicle manufacturers and battery factories. They are tasteless and it is a pity to discard them. On the one hand, waste batteries still have certain application prospects and recycling value; on the other hand, the cascade utilization of waste batteries is still in the theoretical stage, and the dismantling and recycling profits are meager or even loss-making.

　　Recently, the national standards publicity and implementation meeting for the "Specifications for Recycling and Dismantling of Vehicle Power Batteries" (hereinafter referred to as "Disassembly Specifications") and "Residual Energy Testing for Recycling and Utilization of Vehicle Power Batteries" (hereinafter referred to as "Residual Energy Testing") were officially held . Can the release of the publicity and implementation meeting solve the current increasingly urgent recycling dilemma faced by the used battery market?

　　In the relevant provisions of the "Dismantling Specifications" and "Remaining Energy Testing", strict requirements are imposed on the safety, operating procedures, storage and management of waste Ni-MH battery pack recycling, and the appearance inspection, voltage identification, and The detection procedures such as charge and discharge current judgment and residual energy test are also stipulated.

　　Although the above regulations have improved industry standards to a certain extent, they have not yet addressed the biggest constraint on the current recycling of used batteries, that is, the issue of battery model and size.

　　The current recycling cycle is divided into two cycles: one is echelon utilization, which is for batteries that cannot be used but have not been scrapped, and is mainly used in power storage; the other is disassembly and recycling, which is for disassembly and recycling of batteries that have lost their capacity and cannot be used anymore. Recycle.

　　First of all, from the perspective of tiered utilization of batteries, there are currently various battery cell types and sizes on the market, and there is a lack of standardized structures suitable for communication base stations, energy storage power stations and household energy storage equipment, which has led to many difficulties in promoting the tiered utilization market. .

　　Secondly, from the perspective of disassembly and recycling, the diversity of battery types makes the recycling and reuse process extremely complicated. The different sizes mean that there are no mature complete sets of equipment available in the industry, resulting in high efficiency and time cost of battery recycling. Enterprises dismantle Recycled batteries have low heat.

　　A salesperson at a 4S store in Beijing that mainly sells new energy told reporters that currently manufacturers do not have relevant policies for battery recycling, so scrapped batteries are generally handled by the 4S store themselves.

　　A BYD insider also confirmed this statement. It said that current regulations do not have mandatory requirements for Ni-MH battery pack recycling. BYD and other car companies involved in the battery business recycle batteries, while most new energy car companies not involved in the battery business do not have clear requirements for recycling.

　　At present, battery companies including Waterma, Guoxuan High-Tech, CATL, AVIC Lithium Battery, BAK and other battery companies have launched battery recycling business. However, due to the lack of cooperation from car companies, the used batteries that can be recycled account for a small proportion of the market. Considering the low economic benefits and lack of application channels, even the recycled batteries are mostly stranded in warehouses, and few are truly efficiently processed.

　　However, driven by the industry's generally optimistic market prospects and social responsibilities, companies have always been enthusiastic about exploring battery recycling business models. In addition to BYD's establishment of efficient dismantling and recycling plants, Ladder has also applied business models in home energy storage and communication base stations. In addition, Waterma has also explored a set of recycling solutions for decommissioned power batteries, that is, batteries with echelon utilization value are used in energy storage power stations and mobile electric vehicles. Batteries that cannot be reused in echelons are regenerated to regenerate decomposed materials to avoid environmental pollution.

　　In addition, companies such as CATL and BAK also have unique advantages in recycling applications. The continuous exploration and maturity of enterprise models will promote technological progress, and technological progress will also promote the improvement of regulations, which in turn will also improve regulations. Further promote technological progress and mature development of models.

　　Although the current battery recycling market is far from mature, with the complementary promotion of regulations, technology, and models, the market will develop in a healthy and orderly direction.
