The prevention and control of heavy metal pollution in the battery industry has always been the focus of industry development The Action Plan for Soil Pollution Prevention and Control clearly states that the prevention and control of pollution in heavy metal industries should be strengthened, the standards for the elimination of backward production capacity in lead-acid batteries and other industries should be raised, and backward production capacity should be gradually withdrawn.

In recent years, China's low-speed electric vehicle development momentum is rapid, the average annual growth rate of more than 50 % Some people even hailed low-speed electric vehicles as China's "fourth-generation national cars.

With the increasing use of the automotive industry, the need to improve the recycling of lithium-ion batteries has become more and more important With their extensive use in various devices and the increasing use of the automotive industry, the need to improve the recycling of lithium-ion batteries has become increasingly important.

The patented technology of the utility model relates to a flow guide device for a single liquid flow battery electrolyte It includes a shell with an internal cavity, an inlet flow channel, a guide flow pump, a reaction zone flow channel arranged in the shell for introducing the electrolyte into a single cell battery, and a transfer channel for supplying the electrolyte to the reaction zone flow channel and connecting with the inlet flow channel for the outflow The electrolytes of the single-cell battery meet together and discharge the outlet flow channel, as well as a stop-board installed in the inlet flow channel, and the transit flow channel is located at the bottom of the flow channel in the reaction area.

According to foreign media reports, according to the previous plan of the Volkswagen Group, it will not be a large-scale market launch of electric car products until 2019 But now VW is getting ready to ensure that the battery components are available to meet its massive production needs next year.

In the process of lithium battery production, the evaluation of battery capacity and performance is a very important link From low capacity mainly used in mobile phones, cameras, hybrid cars(<10A) To the medium capacity(10A-30A) for computers, electric motorcycles, electric vehicles, and then to the high-capacity lithium-ion battery for electric vehicles(30A-120A), all tests are required.

Going to parks, going to Beijing suburbs, shopping malls .

Advanced lithium-ion batteries with outstanding energy storage advantages in terms of capacity, safety and stability have become an indispensable part of people's daily work and life They have been widely used in portable electronic products, electric vehicles, and even power grid peaking and other secondary power systems.

 Recently, when the company said that the company has now achieved high nickel 811 positive material mass production, the production of 811 positive material is mainly used for new energy car power batteries At the beginning of 2018, Guoxuan Gaoke stated that it had developed a ternary 811 material soft package core with an energy density of 302 wh/kg.

The microscopic process of charging Lithium batteries are called "rocker type" batteries, with electric ions moving between positive and negative poles, achieving charge transfer, supplying external circuits or charging from external power sources In the specific charging process, the external voltage is loaded at the two poles of the battery, and the lithium ion is de-embedded from the positive electrode material and enters the electrolyte.
