  • Vacuum Planetary Mixer Delivery to Our Russia Customer
    Vacuum Planetary Mixer Delivery to Our Russia Customer Mar 25, 2020
    Today we had finished the package of the vacuum planetary mixer for our Russia customer.The mixing machine is used for lithium battery slurry mixing. The preparation of the battery electrode slurry is the most critical part of the whole process. The quality of the electrode slurry directly affects whether the next step can be performed. Slurry preparation is a non-Newtonian high-viscosity fluid formed by mixing powders and liquids such as living materials, adhesives, solvents, and thickeners. The fluid needs to have a certain viscosity, good fluidity, and a sufficiently small particle size. What kind of equipment does the electrode slurry preparation need to meet the requirements? Have a good vacuum-tight system There are three main reasons why a mixer needs a good vacuum-tight system: ① During the whole mixing process, due to frequent collision and friction between materials, and friction between the agitator and the material, more heat will be generated, resulting in temperature rise. Increasing temperature will cause some solvents to be emitted, which will produce great irritating odors, such as NMP, PVDF, etc. Organic gas will cause great harm to human body. ②In the dry powder premixing stage, if the closed system is not good enough, it will cause dust to rise, destroy the working environment, affect product quality and cause harm to employees. ③ There are large voids inside the powder. After mixing with the solvent, there will be many air bubbles inside the slurry. The slurry needs to be defoamed in order to perform electrode coating, otherwise bubbles will break during the coating process, the areal density is different, and even the foil is exposed, which is extremely detrimental to the battery performance. The material of the mixer has strong corrosion resistance, wear resistance and stable physical and chemical properties Obviously, regardless of the strong alkalinity of the positive electrode material, the strong corrosion resistance of NMP, etc., the mixer needs to have excellent corrosion resistance. During the stirring process, the continuous stirring of the powder by the agitator requires that it has abrasion resistance and a sufficiently long service life. The mixing blade structure is reasonable and the design of the stirring speed meets the requirements In addition to having sufficient stirring power and stirring range in the mixer, the shape and mechanical design of the blades of the mixer have a great influence on the preparation of the slurry. First, it is necessary to ensure that the stirring range of the stirrer is large enough and there is no dead angle in the stirring container. At present, larger-shaft mixers use biaxial or even triaxial planetary agitators to ensure that no powder or agglomerated living materials are not uniformly mixed into the slurry. Secondly, the shape design of the mixer has an absolute impact on the dispersion, mixing, particle size distribution, and fluidity of the material. At present, the c...

  • The Influence of Coating Process for Lithium Battery Performance
    The Influence of Coating Process for Lithium Battery Performance Mar 04, 2020
    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.

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.

  • TOB NEW ENERGY Supercapacitor Pilot Line Equipment
    TOB NEW ENERGY Supercapacitor Pilot Line Equipment Feb 12, 2020
    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.
