How does the specific energy of the LFP battery exceed 180wh/Kg? Will monomer specific energy exceeding 180Wh/kg become a new watershed in power battery product technology? Recently, the Ministry of Industry and Information Technology issued the "Lithium-ion Battery Industry Specification Conditions (2021 Edition)", Among them, the "Specification Conditions (2021)" mentioned that for the newly constructed power battery project, the energy density of the energy-type power battery project should be ≥180Wh/kg, and the energy density of the battery pack should be ≥120Wh/kg. In addition, the "Specification Conditions (2021)" also set requirements for the performance of expansion projects such as cathode materials, anode materials, electrolytes, and separators. At present, the energy density of mainstream ternary battery cells produced in the industry is generally above 210Wh/kg, while the energy density of mainstream LFP battery cells is generally below 180Wh/kg. This means that once the technical indicators are implemented, they will have a certain impact on the industrialization of LFP batteries. Industry insiders believe that, from a technical point of view, the energy density of LFP cells can be achieved beyond 180Wh/kg, but from the point of view of industrialization, it still has certain technical difficulties for power battery companies. For power battery companies, there are mainly the following paths to achieve the energy density of LFP batteries exceeding 180Wh/kg: One is to optimize the material system, such as upgrading the cathode material from lithium iron phosphate to lithium iron manganese phosphate, adopting silicon-doped lithium supplement technology, introducing new electrolytes and ultra-thin copper foil, etc., to increase the energy density of the cell. The second is to optimize the cell structure design, increase the size of the cell to increase the battery capacity, increase the capacity of a single cell to at least 180Ah, and use lightweight technology to reduce the weight of the cell.

Battery stacking process is mainly used for pouch cell and Aluminum case battery. The stacking process uses multi-pole pieces in parallel to make the internal resistance of the battery smaller and the charging efficiency higher; and the heat generated during the charge and discharge cycle is relatively small and more uniform, and the battery safety is higher. In addition, the lamination process makes the internal space of the battery more fully utilized, and the      battery energy density is relatively larger. Therefore, the lamination process is favored by the intelligent manufacturing of lithium batteries

Facing the rapid expansion demand of power lithium battery, it is the core link of the front-end process of lithium battery production.coating is regarded as the top priority in the lithium battery manufacturing process.the implementation of the coating process affects the consistency, safety, and life cycle of the finished battery.Different battery companies differ in terms of raw materials and processes.As a result, the performance index requirements of the coating machine are also different.With changes in process requirements, the coating machine has become one of the bottlenecks for scale expansion The coating process of high-quality lithium-ion batteries not only solves the horizontal and vertical consistency of areal density, but also improves the key indicators of coating width, speed, and intelligence. It is also required that the coating machine must avoid problems such as cracks, bubbles, metal leakage, scratches, and wrinkles. We has increased its investment in coating machine research and development. After the technical team has concentrated on research and multiple experiments, it has overcome a series of technical difficulties and launched a double-layer high-speed wide-width coating machine (currently the maximum range of  Lyric Robot  coating machine has reached 1400mm , The speed reaches 65-90m/min)On the basis of increasing the coating speed and amplitude, it effectively solves the above-mentioned industry pain points.

As a key part of the lithium battery manufacturing process, the ultrasonic welding process is applied to the lithium battery; aluminum foil/copper foil positive and negative current collectors, electrodes, and battery packaging are connected at multiple locations. Any defect in the welded joint will affect the consistency of the performance of the lithium battery. So it is necessary to understand the ultrasonic welding process. In the ultrasonic welding process, the sensor converts high-frequency electrical signals into ultrasonic vibration signals. The high-frequency vibration is transmitted to the surface of the welded metal through the welding joint, and the interface metal oxide film is broken under a certain pressure and strength. Ultrasonic vibration and friction, under the combined action of friction and ultrasound, further soften the flow and diffusion of plastic, gradually increase the connection area and finally realize the connection. The strength of the welded joint decreases as the pressure increases. The welding pressure changes the sliding resistance. A small welding pressure will cause the sliding resistance of the interface to be small, so that the energy generated by friction is not enough to form an effective connection at the interface, and the welding pressure will cause the tool head to be pressed too deeply. Therefore, the advancing welding pressure parameter plays a decisive role in welding quality. The welding time directly affects the energy input during the welding process, and has a direct effect on the welding effect. The welding time is too short and the input energy is insufficient. Due to insufficient friction, it is difficult to form an effective solder joint; if the welding time is too long, the temperature rises and mutual friction causes the workpiece material to soften. The oxide film at the interface of the welding zone is destroyed and plastic deformation, which can form more Good connection, when the welding time is further extended, the welding head is likely to form deeper marks on the surface of the workpiece, which will affect the welding effect. If the welding time is too long, it will easily cause the welding head and the workpiece to be welded. In the ultrasonic welding process, the vibration system formed by the workpiece and the workpiece directly affects the instantaneous speed of vibration at the interface of the workpiece, and ultimately affects the frictional heating and plastic deformation, thereby affecting the welding quality.

First, adjust the power switch of the electrode rolling machine,Then wipe the steel roller with a cloth dipped in alcohol. Confirm the following three points before starting up. 1. Check that the emergency stop switch remains connected before powering on 2. The surface of the steel roller is dry, clean, free of oil and particles. 3 Adjust the gap between the steel rollers. There are different rolling parameters in the battery mode. Don't move around here. Pay attention to the rolling stroke to avoid motor failure. Second, take a suitable electrode roller press, 1 Adjust the gap between steel rolls to the range of process requirements. 2. Keep the balance between the electrode and the micrometer. Place the material on the unwinding shaft and adjust it to a proper position. Place the electrode between the two rollers. The electrode is required to be parallel to the front and back, and cannot be mounted sideways in the air or tilted. Turn on the tension system and automatic correction system in front of the roller press, and pay attention to adjusting the tension not too tight or too loose. Third, during the electrode rolling process, the weight requirements are as follows: 1. Pay attention to the perpendicularity of the electrode and the micrometer. 2. Keep the hand movement speed the same as the electrode movement speed. After the material is rolled, the surface of the roller should be wiped. Use an anti-rust agent to wipe the surface of the roller to keep it clean. If there are no two roller presses, one roller press must be used to process the cathode and anode at the same time, and the roller must be cleaned. In addition, the electrode will have moisture after being rolled, so it should be placed in an oven for baking.
