Battery coating process is generally refers to the slurry evenly stirred evenly coated on the fluid collection, and drying the organic in the slurry.The effect coating have a big influence for battery capacity, internal resistance, cycle life and safety, to ensure the uniform coating.The choice of coating method and control parameters have an important impact on the performance of lithium ion batteries, mainly in the following aspects: 1) coating drying temperature control: if the coating drying temperature is too low, it can not ensure that the electrode is completely dry, if the temperature is too high, it may be because of the organic solvent inside the electrode evaporation too fast, the surface coating on the electrode cracks, falls off and other phenomena; 2) coating surface density: if the coating surface density is too small, the battery capacity may not reach the nominal capacity; if the coating surface density is too large, it is likely to cause waste of ingredients. In case of serious excess anode capacity, lithium dendrite punctures the battery membrane, resulting in a short circuit, causing potential safety hazards; 3) coating size: coating size is too small or too large may lead to the anode cannot be completely cathode around inside the battery, in the process of charging, lithium ion from the positive embedded, moved to the electrolyte is not cathode completely encase, cannot efficiently exert the anode real capacity, serious, lithium inside the battery will form the dendrite, easily pierced diaphragm lead to circuit inside the battery; 4) coating thickness: if the coating thickness is too thin or too thick, it will affect the subsequent pole rolling process, and the performance consistency of the battery electrode cannot be guaranteed. In addition, the electrode coating is of great significance to the safety of batteries.Before coating, 5S work should be done to ensure that no particles, debris, dust, etc. are mixed into the coating process. If mixed with debris, it will cause a small short circuit inside the battery, which will cause the battery to catch fire and explode seriously. Our battery coating machine can accuracy to achieve the parameter that you need to ensure of the requirement of your battery.

Battery Pack consists of battery , bus-bar, soft connection, protective board, outer packing, output (including connector), highland barley paper, plastic support and other auxiliary materials. TOB New Energy offers a full set of battery pack equipment for battery manufacturming. The characteristics of the battery PACK The battery PACK requires the battery to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life). The cycle life of the battery PACK is lower than that of a single battery. Use under limited conditions (including charging, discharge current, charging mode, temperature, etc.) Lithium battery PACK formed after the battery voltage and capacity has been greatly improved, must be protected, the charge balance, temperature, voltage and over current monitoring. The battery PACK must meet the voltage and capacity requirements required by the design. The process of battery PACK the PACK of the battery can be realized in two ways. One is through laser welding or ultrasonic welding or pulse welding. This is a commonly used welding method.Second, contact through elastic metal sheet, the advantage is no welding, easy to replace the battery, the disadvantage is may lead to poor contact The requirement of the battery pack process During the process of PACK, such as nickel sheet, copper-aluminum composite bus, copper bus, total positive and total negative bus, aluminum bus, and copper soft connection, aluminum soft connection, copper foil soft connection, etc.The processing quality of busbar and soft connection needs to be evaluated from these aspects. Whether the material material is composite requirements, bus material is not up to the standard will increase the resistivity, especially need to confirm the composite ROHS related requirements. The key size processing is in place.The out-of-tolerance of key dimensions may lead to insufficient safety distance between high voltage devices during the assembly process and cause serious safety risks. (3) soft connection of the hard zone bonding force and soft zone stress absorption. (4) whether the actual processing of the soft connection and bus through the flow capacity of the design standards, whether the insulation of the thermoplastic casing is damaged.

Supercapacitor refers to a new type of energy storage device between traditional capacitors and rechargeable batteries. It has both the characteristics of fast charging and discharging of capacitors and the energy storage characteristics of batteries. Compared with batteries and traditional physical capacitors, the characteristics of supercapacitors are mainly reflected in: (1) High power density. It can reach 102 ~ 104 W / kg, which is much higher than the power density level of the battery. (2) Long cycle life. After a few seconds of high-speed deep charge-discharge cycles of 500,000 to 1 million times, the characteristics of the supercapacitors change little, and the capacity and internal resistance are only reduced by 10% to 20%. (3) Wide working temperature limit. Since the adsorption and desorption speed of ions in a supercapacitor does not change much at low temperatures, its capacity change is much smaller than that of a battery. Commercial supercapacitors can operate at temperatures ranging from -40 ° C to + 80 ° C. (4) Maintenance-free. Supercapacitors have high charge and discharge efficiency, have a certain tolerance for overcharge and overdischarge, can be repeatedly charged and discharged stably, and theoretically do not require maintenance. (5) Green and environmental protection. Super capacitors do not use heavy metals and other harmful chemicals in the production process, and have a long life span, so they are a new type of green environmental protection power supply. Now,our company have the full set super capacitor equipment about the super capacitor pilot line.The slurry mixing→electrode coating→electrode rolling→battery tab riveting→feeding in the case→filling the electrolyte→grooving sealing→secondary sealing.
