High-energy-density lithium-ion batteries are a key research and development direction in my country, and also a disruptive change in the field of new energy. my country proposed in the "13th Five-Year" new energy vehicle pilot project "High Specific Energy Lithium-ion Battery Technology", a common key technology research project, that by 2020, the battery cell energy density ≥ 300, the cycle life ≥ 1500 times, the cost of ≤0.8 yuan/Wh, the safety performance meets the requirements of t

Some time ago, Bill Ford, executive chairman of Ford Motor Company, announced the next stage of its development strategy in China, the China 2025 Plan. On the same day, GM held a 2017 GM China "Explore Experience of Electrification Technology" event in Shanghai. The two fuel car companies announced the transition to electrification, and two more veterans were added to the new energy electric vehicle force. Under the influence of the decline of financial subsidies and the double-point policy, behind the pr

We all know that there are four major processes in vehicle manufacturing, namely: stamping, welding, spraying and final assembly. According to the author's professional experience, the author believes that the power battery PACK also has four major processes. They are: 1) Assembly process; 2) Air tightness testing process; 3) Software flashing process; 4) Electrical performance testing process; The following briefly introduces the four major manufacturing processes of power battery PACK. 1. As

Plane positioning of slitting equipment: In order to ensure that the slitter equipment is accurately positioned on the basis of the equipment, after the equipment is hoisted in place, a reference line should be hung according to the central target plate that has been set. For the suspension of the reference line, a whole steel wire with a diameter of 0.3～0.75mm should be selected according to the equipment installation accuracy requirements and the suspension span. The tension force is generally 40%～80% of the bre

PVC slitting machine is suitable for slitting thin materials such as non-woven fabrics, leather, plastics, environmental protection materials, etc. After adjusting the cutter distance mechanism by this machine, it can cut into the required round roll strips, then you know Is the PVC slitting machine used and maintained? The editor will explain it for you below.        1. The operator must grasp the plan of the gate hoist, the function of the inspection machine and the operation method

The paper separator is to rewind and cut the large-axis base paper into different specifications of paper for the production of napkins, facial tissues, etc. Do you know the technical points and advantages of the paper separator system? The editor will explain it for you below.  Technical points:  1. The overall slitting speed of the paper separator system is high, and it is the same as low-speed operation when operating in the weak magnetic area, with fast response and stable speed.  2. The t

After the laser cutting machine cuts the material, the finished product will occasionally show the phenomenon of crystal dots. There are two main reasons. One is that the raw material itself has crystal points, and the other is that dust is generated during the cutting process, and the dust is mixed into the subsequent processes. To solve these two problems, first start with the raw materials, pay attention to inspections when purchasing raw materials, and second, avoid the generation of crystal points when laser

The manufacturing process steps of lithium battery pole pieces can be subdivided into five processes: slurry preparation, slurry coating, pole piece rolling, pole piece cutting, and pole piece drying. It is understood that the battery assembly process is roughly divided into winding, casing, welding and other processes according to different battery specifications. The final liquid injection stage includes various processes such as liquid injection, exhaust, sealing, pre-filling, formation, and aging.(Cutting and s

The cell of a lithium battery is made up of many pole pieces stacked or wound up. Before doing this set of procedures, we must first use a slitting machine to cut the pole pieces into the size and shape we need. Nowadays, the cutting method of die-cutting machine is usually adopted on the market. This equipment has high efficiency and low cost. The price of a die-cutting machine with high-quality pole piece products is about one million yuan.(High Speed Slitting Machine) J390-590D-BY flexible die cutting machine
