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. Today we have sent 5sets TOB-R-203 and 2sets TOB-AT526 to one of our customers in India. thank you very much for your cooperation and support,I believe you will be very satisfied. 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

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%). TOB NEW ENERGY LIMITED is a technical company focused on the lithium battery materials and equipments, we have ability to build a laboratory line, pilot production line, EV battery production line. Welcome to discuss and study the lithium battery technology with us: Contact Person: Mr.Runner (Engineer & Sales) Email: tob.runner@tobmachine.com Skype: tob.runner@tobmachine.com

Spot welding machine shipment On Mar.13th,we have send one set of TOB-HDP-3000S Battery Spot Welding Machine to Italy.This battery spot welding machine can welding thickness from 0.03mm -0.5mm ,and can welding Multiple welding sheet.also with LCD display This is our new design product,with high quality and competitive price,this new design spot welding machine has lots of advance,such as: It’s DC output.Heat concentration,the heat efficiency is increased, the welding process is stable, the welding quality is improved, and the electrode life is prolonged. High speed and high precision microprocessor (MCU) control, to provide highly stable repetitive welding, with current monitoring function. High speed welding: a quick start and high polarity switching reduced the temperature effect so that make the welding surface clean and beautiful. olarity switching: suppression of asymmetrical result makes the two points welding strength uniformand extends the service life of the electrode. The imported IBGT module full control the discharge,welding quality and welding speed , non ordinary welding machine can compared with it. Double pulse can reduce welding spatter, effectively improve the quality of welding. Data storage using EEPROM, no battery life issues, always returned to the previous use of welding procedures when you starting up We are always trying our best to improve and innovate products,hope to meet the market demand,to be top of best.
