Focus: lithium-ion battery pack needs to strengthen resource recycling and lifecycle management. The ladder recycling of lithium-ion battery packs has always been a focus problem, and there is no complete solution yet. Some experts pointed out that my country should establish full life cycle management of the power and energy storage battery system, strengthen comprehensive use of resources, and jointly promote sustainable society.

At present, the state emphasizes the management of powerful lithium battery recycling management, establishing a dynamic lithium battery step utilization and recycling management system, so resources will not be wasted. Electric cars, smartphones, smart bracelets, sweeping robots . Electronic products have gradually become a necessity.

In this way, the power and energy storage batteries are more and more widely used in various fields of production and life. During this process, the safety of large-capacity lithium-ion battery packs, the recovery and ladder utilization of waste batteries, etc. are the focus of social attention.

Lithium-ion battery pack is to be solved by my country's Chemistry and Physical Power Industry Association, my country has become the most active area of ​​global lithium-ion battery packs. In 2016, my country's lithium-ion battery market was about 111.5 billion yuan, and the demand for dynamic lithium-ion batteries was 60.

5 billion yuan, up 65.8% year-on-year. In 2020, the demand for dynamic lithium battery will reach 5 times in 2015.

Although my country's battery production is the world, the unit production profits is lower than Japan. The reason why my country's battery industry has high yield, low-income, because lack independent intellectual property rights. my country has a certain gap between the core raw materials and components of lithium-ion battery packs and the production process.

New energy car's battery life is a highlight of lithium-ion battery pack level. The data shows that in 2017, my country's new energy vehicle guarantee is 1.53 million, which is expected to exceed 5 million marks in 2020.

But most electric car battery life, may not support the vehicle from Shanghai to Hefei. The lithium-ion battery pack after use has left many hidden dangers. The executive chairman of the meeting, Professor Xiamen University, Sun Shigang, academician of the Chinese Academy of Sciences, said that the waste of lithium-ion batteries exists and other safety hazards, and the environmental pollution is seriously polluted.

The full life cycle management method is urgently needed to perform in the opinion, "Full Life Cycle Management" is expected to be an effective means to solve the many problems of lithium-ion battery packs. Full life cycle management can be divided into three stages of design production, one use and ladder utilization and recycling. In 2016, Samsung Galaxy Note7 mobile phone announced only more than a month, in the world, more than 30 explosions and fire accidents caused by battery defects.

In order to prevent such an accident, improve from battery design. In the design method, the model is set by the model to set various design parameters and then in the production of the experiment, and the production line can surround the stability and product safety of the production line, the test line, the three-wire consolidation of the medium test line and the quantity production line Fast transition. Accurate assessment and prediction of lithium-ion battery status is the key to efficient use of power systems.

On the one hand, the battery system for service hours is required to evaluate and predict the performance of its different life phases; on the other hand, it is necessary to evaluate the safety performance evolution under the full life cycle of the battery system. And the ladder is expected to promote circular economy with waste batteries. For example, regarding the low-capacity lithium ion battery pack, it can be applied to low-speed vehicles and energy storage.

After the capacity is depleted, crushing decomposition can be made, and effective substances can be extracted. At present, researchers have made certain progress in the recovery process of lithium-ion battery packs, and has developed new processes with waste negative granks. This process is more efficient and low, which can make full use of its heat and restraint, and enriched recycled lithium resources, with environmental protection and economic benefits.

Effective supervision is urgently needed to introduce in the view, current lithium-ion battery production, use, recycling, etc., regulatory status is still in a state of disorder. In the design and production stage of the pre-battery, the relevant agencies have not established standards and effective supervision.

The design of the lithium-ion battery pack is the basis for achieving the decomposition of green environmental protection materials. The state should specify the relevant legal system, and standardize the responsibility of the recovery and renewable use stage after the consumption of production products. At the same time, the administrative department should strengthen market regulation, optimize organizational management, and further improve the supervision mechanism for full life cycle systems.

Lithium-ion battery pack energy-saving green environmental protection has become a development requirement with the development of technology and economics, energy and environmental problems have become increasingly prominent, and the uninterruptible power industry should develop to "green, environmental protection". From my country's policy trends, countries have issued various policies to increase support for low-carbon environmentally friendly economies, which is undoubtedly a good opportunity for lithium-ion battery low green environmental economy. Lithium-ion battery packs are associated with domestic manufacturers, the consistency, stability, safety, environmental protection, and loop life, etc.

, which are also very attractive to the downstream manufacturers.
