It fundamentally alleviates the cost and mileage anxiety of lithium ion battery manufacturing

New energy vehicle manufacturers are now facing the dilemma of battery anxiety. Because the development of fuel-powered lithium battery technology is difficult to apply and replace pure electric vehicles on a large scale in a short time, and new batteries (lithium air lithium sulfur, etc.) are still in the basic research stage, lithium-ion batteries will be listed as the first choice in the field of new energy vehicle power lithium-ion batteries for a long time due to their light weight, high energy density, green environmental protection, etc.

Generally speaking, the manufacturing process of lithium-ion battery is complex, including electrode processing, battery package construction and cell assembly, and then electrical testing to evaluate the capacity and performance of the battery, as well as the rating in work. The dew point of RongHuaCheng Hu Jintao Shuoqi is the key process in the lithium-ion battery manufacturing industry. Through the precise control research of the battery charging and discharging process, there is an activation effect. The former makes the battery start to have the ability to store and release electric energy. This is to separate the battery with similar characteristics, improve the consistency of battery products, and ensure the high performance of the vehicle power lithium-ion battery pack. This is a time-consuming process, which requires multiple charging and discharging to activate the chemical reaction of the battery. However, this process is necessary to ensure the reliability and quality of the finished battery.

Lithium-ion battery manufacturing process

Hu said that the fractional conversion of lithium-ion batteries accounted for more than one-third of the total cost of the entire manufacturing process, so it was one of the bottlenecks that battery manufacturers could not increase production and thus reduce the total cost of battery processing. Lithium ion battery manufacturers are eager to reduce the time required by RongHuaCheng on the premise of ensuring safety, collect and monitor lithium ion batteries with higher density of parameters from more aspects, make the charging and discharging process more efficient and energy-saving, reduce the floor area of equipment, reduce the use of cables and heat, and achieve lower costs and energy efficiency. In addition, in order to improve the electrochemical performance of the battery, such as cycle life, stability, self-discharge, safety, etc., it is necessary to strictly control the consistency of the lithium-ion battery or accurately evaluate the battery level, so it is very necessary to divide the measuring accuracy and capacity of the converted current and voltage. Therefore, after comprehensive consideration of cost and other factors, battery manufacturers are more inclined to work closely with the specialized knowledge and suppliers at the level of steering test system, not only to obtain more complex components and building blocks, but also to obtain more likely reference design system architecture, so that the time to market is three to four times longer than that of developing and testing the system from scratch, and at the same time, to ensure the accuracy and reliability of battery access, and to conduct testing and measurement.

For battery test suppliers, it is not easy to meet the requirements of efficient and accurate battery separation and conversion test. At the front end of the simulation, the power supply driving the battery charging circuit should be strictly controlled. At a deeper level, the formation and testing of the battery should closely monitor the distribution of current and voltage used in the battery cycle to prevent overcharging and under-charging. ADI is one of the few professional suppliers that can meet the precise testing requirements of battery manufacturers.
