lithium battery is composed of active material, conductive agent, binder, etc.<\/p><p>First, confirm and bake the raw materials. Generally, the conductive agent needs to be baked at \u2248120\u2103 for 8 hours, and the binder PVDF needs to be baked at \u224880\u2103 for 8 hours. Whether the active material (LFP, NCM, etc.) needs to be baked and dried depends on the raw material status. Currently, the general lithium battery workshop requires temperature of \u226440\u2103 and humidity of \u226425%RH.<\/p><p>After drying is completed, the PVDF glue solution (PVDF solute, NMP solution) needs to be prepared in advance. The quality of PVDF glue is crucial to the internal resistance and electrical performance of the battery, and the factors that affect glue application include temperature and stirring speed.<\/p><p>The higher the temperature, the yellowing of the glue will affect the adhesion. If the stirring speed is too high, the glue will be easily damaged. The specific rotation speed depends on the size of the dispersion disk. Generally, the linear speed of the dispersion disk is 10-15m\/s (high dependence on equipment). At this time, the mixing tank is required to turn on the circulating water, and the temperature should be \u226430\u2103.<\/p><p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-113621\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/cathode-batching.webp\" alt=\"cathode-batching\" width=\"1000\" height=\"600\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/cathode-batching.webp 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/cathode-batching-300x180.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/cathode-batching-768x461.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/cathode-batching-600x360.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p>Batch the cathode slurry. At this time, you need to pay attention to the order of adding materials. First add the active material and conductive agent, mix slowly, and then add the glue. The feeding time and feeding ratio must also be strictly implemented according to the lithium battery manufacturing process.<\/p><p>Secondly, it is necessary to strictly control the revolution and rotation speed of the equipment. Generally, the dispersion linear speed should be above 17m\/s. It depends on the performance of the equipment. Different manufacturers vary greatly. Also control the vacuum and temperature of the stirring.<\/p><p>At this stage, it is necessary to regularly detect the particle size and viscosity of the slurry, and the particle size and viscosity are closely related to the solid content, material properties, feeding sequence and lithium battery manufacturing process. At this time, the conventional process requires temperature of \u226430\u2103, humidity of \u226425%RH, and vacuum degree of \u2264-0.085mpa.<\/p><p>Transfer the slurry to the transfer tank or coating workshop. When the slurry is transferred out, it needs to be screened. The purpose is to filter large particles, sedimentation and remove ferromagnetic and other substances. Large particles affect the coating and may lead to the risk of excessive battery self-discharge or short circuit; excessive ferromagnetic material in the slurry may lead to excessive battery self-discharge and other defects.<\/p><p>The process requirements at this lithium battery manufacturing process is: temperature\u226440\u2103, humidity\u226425%RH, screen mesh\u2264100 mesh, and particle size\u226415um.<\/p><h2 id=\"anode-batching\">Anode batching<\/h2><p>The anode of lithium battery is composed of active material, conductive agent, binder and dispersant.<\/p><p>First, confirmation of raw materials. The conventional anode system is a water-based mixing process (the solvent is deionized water), so there are no special drying requirements for the raw materials. This lithium battery manufacturing process requires the conductivity of deionized water to be\u22641us\/cm. Workshop requirements are: temperature\u226440\u2103, humidity\u226425%RH.<\/p><p>Prepare glue solution. After the raw materials are confirmed, the glue solution (composed of CMC and water) should be first prepared. At this time, pour graphite C and conductive agent into the mixer for dry mixing.<\/p><p>It is recommended not to vacuum and turn on the circulating water, because the particle extrusion friction and heat generation are serious during dry mixing. The speed is low speed 15~20rpm, and the scraping cycle is 2-3 times with an interval of \u224815min.<\/p><p>Pour the glue solution into the mixer and start vacuuming (\u2264-0.09mpa). Scraping cycle at low speed 15~20rpm for 2 times, then adjust the speed (low speed 35rpm, high speed 1200~1500rpm), and run for 15min~60min, depending on the wet process of each manufacturer. Finally, pour SBR into the mixer.<\/p><p>It is recommended to stir at low speed, because SBR is a long-chain polymer. If the speed is too fast for a long time, the molecular chain will easily break and lose activity. Recommended low speed is 35-40rpm, high speed is 1200~1800rpm, for 10-20min.<\/p><p>Test the viscosity (2000~4000 mPa.s), particle size (35um\u2264), solid content (40-70%), vacuum and sieve (\u2264100 mesh). The specific process values will vary depending on the physical properties of the material and the mixing process.

If the pole lug is exposed too long, short circuit is easy to happen between the pole lug and the steel shell during rolling groove.<\/p><p>If the pole lug is too short, the cap cannot be welded. At present, ultrasonic welding heads are available in linear and point shapes, and domestic processes mostly use linear ones due to overcurrent and welding strength considerations.<\/p><p>In addition, high-temperature glue is used to cover the tabs, mainly to avoid the risk of short circuit caused by metal burrs and metal debris.

Lug length and shaping width also need to be considered. The ambient temperature of this workshop should be\u226423\u2103, the dew point should be\u2264-30\u2103, and the moisture content of the anode should be\u2264500-1000ppm.<\/p><h2 id=\"winding\">Winding<\/h2><p>Winding is to wind the separator, cathode sheet, and anode sheet into a single core through the winding machine. The principle is to use the anode to wrap the cathode, and then separate the cathodes and anodes through a separator.<\/p><p>Because the anode of the conventional system is the control electrode of the battery design, the capacity design is higher than that of the cathode, so that the Li+ of the cathode can be stored in the &#8220;vacancy&#8221; of the anode during formation charging. Winding requires special attention to winding tension and pole sheet alignment.<\/p><p>Small winding tension will affect the internal resistance and shell insertion rate. While excessive tension may cause the risk of short circuit or fragmentation. Alignment refers to the relative position of the anode, cathode and separator. The width of the anode is 59.5mm, the cathode is 58mm, and the separator is 61mm. The three are aligned in the play to avoid the risk of short circuit.<\/p><p>The winding tension is generally between positive tension 0.08-0.15Mpa, negative tension 0.08-0.15Mpa, upper diaphragm tension 0.08-0.15Mpa, and lower diaphragm tension 0.08-0.15Mpa. The specific adjustment depends on the equipment and process. The ambient temperature of this workshop should be\u226423\u2103, the dew point should be\u2264-30\u2103, and the moisture content should be\u2264500-1000ppm.<\/p><figure id=\"attachment_113630\" aria-describedby=\"caption-attachment-113630\" style=\"width: 1000px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-113630\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/Schematic-of-winding-into-a-core.webp\" alt=\"Schematic-of-winding-into-a-core\" width=\"1000\" height=\"600\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/Schematic-of-winding-into-a-core.webp 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/Schematic-of-winding-into-a-core-300x180.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/Schematic-of-winding-into-a-core-768x461.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/Schematic-of-winding-into-a-core-600x360.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><figcaption id=\"caption-attachment-113630\" class=\"wp-caption-text\">Schematic of winding into a core<\/figcaption><\/figure><h2 id=\"shelling\">Shelling<\/h2><p>Before the core is put into the shell, Hi-Pot test voltage 200~500V is required (to test whether there is a <span style=\"text-decoration: underline;color: #333399\"><a style=\"color: #333399;text-decoration: underline\" href=\"https:\/\/www.takomabattery.com\/the-ultimate-energy-source-high-voltage-battery\/\" target=\"_blank\" rel=\"noopener\">high voltage battery<\/a><\/span> short circuit), and also dust suction treatment is required, to further control dust before being put into the shell.<\/p><p>The three major control points of lithium batteries are moisture, burrs, and dust.

Commonly used welding pins are \u03a62.5*1.6mm, and the welding strength of the anode tab should be\u226512N to be qualified.<\/p><p>If it is too low, it will easily lead to false welding and the internal resistance will be too high. If it is too high, it will easily weld off the nickel layer on the surface of the steel shell, resulting in solder joints, leading to hidden dangers such as rust and liquid leaking.<\/p><p>The simple understanding of rolling groove is to fix the winding core in the shell without shaking. In this lithium battery manufacturing process, special attention must be paid to matching the transverse extrusion speed and the longitudinal pressing speed to avoid cutting the shell if the transverse speed is too high, and the nickel layer of the notch will fall off if the longitudinal speed is too fast or affect the height of the groove to affect the sealing.<\/p><p>It is necessary to check whether the process values of groove depth, expansion, and groove height meet the standards (through actual and theoretical calculations).<\/p><p>Common hob specifications are 1.0, 1.2, and 1.5mm. After the rolling groove is completed, the entire machine needs to be vacuumed again to avoid metal debris. The vacuum degree should be\u2264-0.065Mpa and the vacuuming time should be 1~2s. The ambient temperature of this workshop is required to be\u226423\u2103, and the dew point is \u2264-40\u2103.<\/p><h2 id=\"battery-cell-baking\">Battery cell baking<\/h2><p>After the cylindrical battery cell has been rolled and grooved, the next lithium battery manufacturing process is very important: baking. During the production process of battery cells, a certain amount of moisture will be introduced. If the moisture is not controlled within the standard in time, it will seriously affect the performance and safety of the battery.<\/p><p>Generally, an automatic vacuum oven is used for baking. The cells to be baked are placed neatly, the desiccant should be placed in the oven, and set the parameters, and raise the temperature to 85\u00b0C (taking lithium iron phosphate cells as an example).<\/p><p><strong>Here are several baking standards of different sizes of battery cells:<\/strong><\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element
