"If you want to be straight, you must be crossed; if you want to know the square, you must. "" Lu's Spring and Autumn "is used in the field of recycling in the current vehicle power lithium battery, coinciding. A few days ago, "The Decomposition Specification for Car Power Lithium Battery Recovery and Utilization" (hereinafter referred to as "Decomposition Specification") and "The Recycling of Driving Power Lithium Battery" (hereinafter referred to as "" 余能 检测 检测 ") Standard publicity will be held.

It is reported that "dismantling norms" and "residual detection" are proposed by the Ministry of Industry and Information Technology, Guangdong Bangpu Circular Technology Co., Ltd., CATL New Energy Technology Co.

, Ltd. (hereinafter referred to as "CATL"), my country Automotive Technology Research Center (below "Socage Center") and other units are drafted, and it is the first national standard for the recycling of power lithium batteries. The "Decomposition Specification" has been announced on May 17, and it is determined this year's December 1 Officially started.

"Yu Can Test" has passed the approval and is expected to formally promulgate in 2018. Global demonstration significance highlights the rapid spread of electric vehicles, the recycling of power lithium batteries has become increasingly urgent. Industry expects that since this year, my country will usher in the first batch of powerful lithium batteries, 2020 commercial vehicles and passenger vehicle power lithium-ion battery scraps will reach 27GWH and 4.

2GWH, respectively. Before the above two standards have not yet been formulated, the state has no very strict policy specification for the recycling of power lithium batteries. The senior engineer of the Automobile Standardization Institute of China Auto Center, the head of the National Automotive Standardization Technology Commission Secretariat, Zhang Pillar reporter, said: "Despite our country to promote the development of industrial development, there is no corresponding standard to guide the industry how safer.

Recycling more rationally using power lithium batteries. In developed countries and regions, this work is also in its infancy, there is no very standardized practice. The launch of "dismantling specifications" and "余能 检测" fill this gap.

"Hunan Bangpu Waste Automobile Circuit Co., Ltd. (hereinafter referred to as" Bangp ") General Manager Yu Navy tells reporters:" Demolition Specification "and" Yu Can Test "and other national standards are the same, it is my country Part of the national standard system for power lithium battery recycling.

The purpose of standard project and development is to provide safety, environmental protection, standard, and efficient guidance norms for electric vehicle power lithium battery recycling operations and operations, and assessment of my country's important waste responsibility units engaged in new energy vehicles and powered lithium batteries in China. Certification criteria and screening basis, while providing basic reference guidelines for supervision supply at all levels. The above two national standards mean that my country is the first country that publishes powerful lithium battery safety dismantling and 余能 检测 检测, has global demonstration.

"Decomposition, the detection process is clear CATL is a representative company of domestic production power lithium batteries. The person in charge said:" There are many domestic dynamic lithium-ion battery models, the battery pack structure is not uniform, the assembly process and technology are also different, this decided nothing A set of dismantles can be suitable for all power lithium batteries. In addition, the unpacking process is very high for the overall technical requirements of the production line, and the recycling of the dynamic lithium battery still has many challenges, the professionalism is not strong, the safety is poor, and the dismantling is irregular.

The introduction of the above two standards will bring a certain degree of improvement in the industry that is still lacking. "As a domestic typical dynamic lithium battery recycling company, Bangpu current key work is concentrated in the system of recycling process technology and process control equipment. "In many people, the power lithium battery recycling and the 'small battery' (such as mobile phone battery) are the same, and the process technology route can be completely copied, but the fact is not the case.

Because of its difference in packaging structure and material system and vehicle PACK, the influencing factors of reverse recovery are large, and the traditional screwdrivers and wrenches can solve the recovery of distinctive violent ideas in the power lithium battery. It will encounter huge security and environmental protection, which may cause fire, dangerous substances, and even explosion. "Yu Navy told reporters," This is not a sensational, to scientifically look at the powerful lithium battery in many subjects such as physics, chemical and mechanical metallurgy.

"Zhang copper column also said:" Since there is still a certain energy due to recycling, if you don't reasonably disassemble, it is easy to cause safety hazards. In addition, if the ladder is used to use, the unpacking of the battery is not damaged after the dismantling, so the specific content of the "dismantling specification" is deployed around the above problems; and "residual detection" Important involves how to detect the remaining capacity of the power lithium battery, we determine whether the battery is still using the value by supply detection method, and then defines and estimates its residual value through market behavior. "It is reported that" dismantling norm "has strictly demanded strict requirements for safety, operation procedures, storage and management of waste dynamic lithium battery recycling, which is beneficial to solve the problem of industry development to a certain extent, standardize my country's driving power Recycling and dismantling, professional technology and dynamic lithium battery recovery system of lithium battery; "余能 检测 检测" standardizes dynamic lithium battery appearance inspection, polarity detection, voltage discrimination, charge and discharge electric current judgment, residual test and other detection Process, the basis for the supply evaluation of the balance of the vehicle power lithium battery, which helps to improve the safety and scientificity of waste power storage battery residual detection.

It is urgent to implement a joint-in-depth investigation of dynamic lithium battery recovery in the whole industry, and learned that my country's lithium-ion battery recycling is now "scattered, chaos, poor", and the main body of the recycling of lithium-ion batteries in the market is important. And professional recycling company, has not yet formed a recycling system with a powerful lithium-ion battery production company or electric vehicle company, and a few large large-scale battery recycling companies in China are also in the exploration stage. Yu Haijun said that engaged in the recycling of power lithium battery, first of all, there is enough professional understanding and understanding of the power lithium battery, from the vehicle to the battery, from the physics to electrochemistry, from metallurgy to the material, to study it with different angles and depths To recognize the risks and hidden dangers of the security, this is the basis and soul of the recycling of the power lithium battery.

"We use the last ring of the entire powered lithium battery industry chain, only to do harmlessness, re-realize resource, and can also achieve branding and internationalization while pursuing high quality, is the subversion industry ' The only way out of the historical positioning of rots is also the correct technical route that truly fulfill the national requirements and industry norms. "He said. It is understood that the powerful lithium battery recycling industry has received less attention before 2015, but now it is placed under a spotlight.

Zhang copper stated that although the above two standards belong to the recommendation norm, they announced that the industry will give priority to the standard requirements to carry out disassembly and testing work. The person in charge of the CATL finally said: "Due to the industrial chain involves consumers, automotive companies, power lithium battery companies, rails, therefore is of great significance to create a restricted-winning industrial chain ecotropic circle is of great significance. We have found that different automatic lithium battery structural differences are different, and the material system and application carrier are also different.

The deadline for life cycle is also different, and the internationalized leverage of cobalt, nickel, lithium strategic resources, how to establish a Meet multi-interest group demand, safety, environmental protection, low-cost recycling system, is a problem that automobile company, power lithium battery company, recycling company and government need to consider.
