One-Step Pressing, it is rolling only once to achieve the designed thickness and density of the battery electrode. Two-Step Pressing, it is rolling the battery electrode to a certain thickness (such as 90μm) at first time, and achieve the designed thickness (such as 70μm) and desired density through the second time pressing. The main purpose
Battery Electrode Transfer Roll Coating Machine Coating roller rotation drive slurry, through adjusting the scraper clearance to adjust the amount of slurry transfer, the slurry is transferred to the substrate(copper foil,aluminum foil, etc.) by the rotation of the coating roller, and according to the process requirements, control the coating thickness to meet the weight requirements.
The function of formation, The internal anode and cathode materials are activated by charging and discharging, and a good SEI film is formed on the surface of the anode. The principle of formation, The formation of lithium cell is the initialization of the battery, which activates the active material of the cell, which is a
Pouch lithium cell refers to the aluminum laminated film for the outer case packing of the battery. Compared with square aluminum shell battery and cylindrical battery, pouch lithium battery in the occurrence of safety hazards in the first gas expansion, or r release energy from the damage. This makes it not easy to explode and
The process of 18650 lithium battery pack is mainly based on the structure of pack battery, and most of the 18650 lithium battery pack process features are similar. The distinctive features of the 18650 lithium battery PACK process are multiple parallel and multiple series. The greatest feature of the 18650 lithium battery Pack is its
There are many kinds of cathode materials for lithium ion batteries. According to the difference of cathode materials, they can be divided into LiNiMnCoO2 NMC(NCM) cathode material, LiNiCoAlO2 NCA cathode material, LiFePO4 LFP cathode, LiCoO2 LCO cathode, LiMn2O4 LMO cathode and Li4Ti5O12 LTO material. Ternary lithium battery refers to the lithium battery that uses three
