Battery Electrode Film Lab Coating Machine common problems 1.How to change the film applicator Clean waste on applicator:Blade is made of steel, adjust the position of tool edge and coating roller to protect coating film. The scraper is made of organic materials,the effect will be obvious if contact with rollers as far as possible. 2.What is the function of the guide roller coating gun stability and transmission 3.The reason why opposite side’s gap is not stable when coating Check the color of sensor will close to the copper foil or aluminum foil or not after drying - adjust the sensor sensing parameters Check the coating parameters whether it is correct in the coating machine operating range 4.What is the control parameters of big lab coating machine Unit speed coating unit tension drying equipment length drying equipment characteristics coating thickness coating curing process parameters 5.What is coating paper Single side copper foil,aluminum foil Double side copper foil,aluminum foil 6.What is coating rate Coating rate unit is kg/m2 micron，or /m2. For example:coating rate is 20 micron( 0.2kg/m2),it means it can coating 20 micron electrode film on coating 0.2kg materials per square meter. And the higher the coating rate,the equipment will be more expensive

Battery internal resistance tester is a instrument used to measure the internal impedance of the battery and battery acid film damage degree. Use the internal resistance value to determine the battery status(in general) the smaller the resistance value, the better the performance of the battery. Therefore, a method of measuring the internal resistance to test battery is a good way to be fast and reliable. TOB-R203 is a portable battery internal resistance tester, is used for lithium battery,lead acid battery, NiCd/Ni MH battery and all kinds of batteries to check the battery performance. TOB-AT526 is a new design battery resistance tester with high precision and stability. It has an ESR test system, can measure supercapacitor, suitable for batch production of batteries.

Lithium battery electrolyte development of the five major trends Lithium battery consists of the outer shell,cathode,anode,electrolyte and separators,electrolyte plays a vital role in battery energy density, power density, wide temperature applications, cycle life, safety performance, etc. Electrolyte is the battery between the positive and negative conduction of the ion conductor,from the electrolyte lithium salt, high purity organic solvents and the necessary additives such as raw materials in a specific proportion. Lithium battery Key Chemical Materials - Electrolyte (Five major Trends) 1.High ratio energy type electrolyte 2.High power type electrolyte 3.Wide temperature type electrolyte 4.Safety electrolyte 5.Long circulating electrolyte. TOB NEW ENERGY focused on lithium battery equipment research and development, and material improvement,looking forward to cooperate with you, to study together and make progress together. Thank you very much for your interest. TOB NEW ENERGY LIMITED Contact person:Gavin Zhu (Engineer & Sales) Email: tob.gavin@tobmachine.com Skype: tob.gavin@tobmachine.com

LiPF6 as additive to enhance lithium battery performance According to the Northwest Pacific National Laboratory studies have shown that to the electrolyte(LiTFSI-LiBOBdual-salt/carbonate-solvent-basedelectrolytes)to add a small amount (0.05M) of LiPF6(lithium hexafluorophosphate), Lithium metal battery charging capacity and cycle stability will be greatly improved. According to the study, the addition of the additive to the lithium metal battery, the 4V cathode at the appropriate high load (1.75mAhcm-2), 500 times after the cycle of its power capacity retention is 97.1%, when charge and discharge current density reached to 1.75mAhcm-2 , the overpotential growth of the electrode is extremely limited. Researchers believe that fast charging and cycling stability thanks to lithium metal surface (solid electrolyte) is durable, electrically conductive and AI cathode current collector. The above figure shows that PNNL will add lithium hexafluorophosphate to the double salt / carbonic acid solvent electrolyte. The cycling stability of the lithium metal battery will be improved, the charging speed will be increased, the voltage will be higher and the charging interval will be longer. PNNL's earlier study was to find a much better electrolyte, which made the battery energy efficient or extremely slow charge, can not be used in high-voltage batteries, or fast charging, but not too Stable, and low battery voltage. Researchers have tried to add lithium hexafluorophosphate (LiPF6, lithiumhexafluorophosphate), which has been used in lithium-ion batteries, to a fast charge electrolyte to form a new electrolyte, while also using lithium anodes and lithium nickel manganese cobalt oxide , So a fast, efficient, high-voltage battery was born. Since this additive has been used in parts of lithium-ion batteries, it is now ready for use and is relatively inexpensive, but its low demand (0.6 wt%).
