two years later, the "15th china international battery technology exchange conference/exhibition (cibf2023)", which has attracted the attention of people from all walks of life in lithium battery industry, will be held in shenzhen world
exhibition&convention center from may 16 to 18, 2023, and xinyuren will also take the "single direction double-sided coating machine" to the exhibition for the first time!
the cibf2023 technical exchange conference will focus on the theme of "power batteries and energy storage batteries", focusing on exploring the latest developments in batteries for electric vehicles and various energy storage batteries for microgrids and smart grids. it is expected that more than 800 people from more than 50 countries and regions will participate in the conference. dozens of domestic and foreign manufacturer information conferences will be held during the same period.
about single direction double-sided coating machine
under the influence of the battery shortage, mainstream lithium battery suppliers in china have embarked on a bold journey of capacity expansion this year, thus promoting the early arrival of the twh era in the lithium battery industry.
benefiting from the scale expansion of lithium battery enterprises, the reputation of lithium battery equipment manufacturers has increased, and the process of replacing domestic equipment has intensified.
after years of in-depth research and development, xinyuren have mass-produced a highly innovative domestic high-end equipment - single direction double-sided coating machine (referred to as single direction double-sided coating
machine), which has become a major highlight in the technological development process of the lithium-ion coating equipment industry in recent years.
as a well-known benchmark enterprise for high-end intelligent manufacturing equipment in china, xinyuren is committed to the research and development, design, manufacturing, and sales of intelligent manufacturing equipment for new energy lithium batteries. after nearly 20 years of dedicated cultivation, the company has formed a rich product line including coating machines, roller presses, slitting machines, assembly lines, drying equipment, etc., and has received a large number of mainstream lithium battery customers including catl, byd, yiwei lithium energy, honeycomb, ruipu, etc.
ultimate pursuit creates four major technological advantages and ultra-high technical indicators
advantage 1: thoroughly solve the problem of affecting the alignment of both sides due to the shrinkage of one side of the electrode during drying when multiple coatings are applied
the single direction double-sided coating machine directly applies the b surface without drying after the a surface is coated, effectively preventing the occurrence of large alignment errors between a and b surfaces caused by the shrinkage of the electrode plates such as hot supply.
advantage 2: the pole piece does not curl, crack, and leave white without wrinkles
the first 1/3 box of the equipment adopts patented heating with electrode opening, and the high capacity design can also discharge at high rates; using a single-layer oven to dry both sides at once, the moisture consistency of the electrode is excellent, completely solving the problems of electrode cracking and curling caused by traditional backflow coating and secondary baking. the sdc coated electrode does not curl, and there are no cracks on the surface of the electrode, resulting in good bonding effect; it can achieve a dryness of electrode plates below 500ppm. compared with traditional technologies, sdc coating significantly improves the performance of the battery (cycle, capacity, self-discharge, internal resistance, etc.).
advantage 3: good consistency on a/b side, consistent moisture content on both sides, and consistent peeling strength of active substances on both sides
the coating slurry on the a/b side comes from the same feeding tank; the consistency of the a/b surface slurry is good, the drying frequency of the ab surface is consistent, and the moisture content is consistent. the ab surface is dried simultaneously, and the stress consistency on both sides is good. at the same time, it can reduce the moisture content of the electrode. based on the above, the a/b surface of the electrode is more uniform and consistent compared to traditional methods.
advantage 4: compared with traditional coating machines, it saves more than 30% energy
obvious. compared to the traditional foldable double-layer coating machine structure design, the single-layer structure design of the single direction double-sided coating machine not only saves a lot of costs in manufacturing, but also significantly saves energy consumption by drying both sides of the electrode after coating, with an overall savings of at least 30%.
in terms of technical indicators, the single direction double-sided coating machine can achieve high requirements for parameter data, far exceeding the standard of ordinary coating. single sided thickness error ≤ ± 1.5 μ m； double sided thickness error ≤ ± 2 μ m； coating surface density ≤ ± 1.0%; in the 1600mm coating width state, the coating speed can reach as high as 110m/min.
diversified substitution, the trend of the times
the process of domestic substitution has accelerated. domestic equipment is developed and manufactured according to the process characteristics of battery production in china, with strong adaptability and obvious cost performance advantages. domestic manufacturers can fully meet the production process needs of customers, and respond quickly. as an outstanding representative of innovative technology, the single direction double-sided coating machine has a significant substitution effect on imported equipment due to its ultra-high cost-effectiveness advantage.
transcendental innovation of sdc technology will gradually replace traditional coating technology. the battery industry is booming, and while battery companies are rapidly expanding, their technology is also in a process of rapid iteration and innovation. only by keeping up with the times and surpassing current technology can the market meet its development needs.
the single direction double-sided coating machine with ultra-high cost-effectiveness and technological advantages will gradually penetrate and spread to more and more battery companies, thereby occupying a larger market share of the coating machine. and xinyuren single direction double-sided coating machine will also evolve towards scale, standardization, and modularity in the future, achieving greater breakthroughs and accelerating industry development.
the china international battery technology exchange/exhibition (cibf) "is an international regular meeting of the battery industry organized by the china chemical and physical power industry association. it is held every two years in china and is the largest exhibition in the international battery industry. here, xinyuren sincerely invites industry experts, customers, and partners to take the time to visit xinyuren booth (hall 7-7t001) and exchange guidance with the company!
