Thin Film Electrolyte

Although high-voltage lithium battery materials are getting more and more attention, these high-voltage anode materials are still unable to achieve good results in practical production and application. The biggest limiting factor is that the electrochemical stability window of the carbonate-based electrolyte is low. When the battery voltage reaches about 4．5（vs．Li/Li＋）, the electrolyte begins to p...

Lithium Chip Metal lithium chip used in the laboratory can provide a far greater source of lithium, Lithium chip shall have less impurities and the size shall be larger than that of the electrode to be measured, and the purity of lithium chip shall not be less than 99.9%. General requirements for lithium chip in the preparation of coin cell: diameter 15 ~ 15.8mm (the corresponding electrode size i...

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 process of energy conversion. The formation of lithium cell is a complex p...

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 thus more secure. At the same time, a pouch lithium battery of the sam...

After the battery cells drying process, the battery cell will be tested for moisture and meet the standard before proceeding to the next step of battery electrolyte filling process（cylindrical cell）. Put the roasted battery cell into the vacuum glove box quickly, weigh it and record the weight, place the injection cup on the upper side of the battery and add the electrolyte into the cup. If not su...

The packaging method of lithium battery depends on the shell material it uses. In general, only lithium pouch batteries will use aluminum laminate film and heat sealing. The metal cans batteries are usually sealed by laser welding. Aluminum laminate film generally has three layers, respectively nylon layer, Al layer, PP layer. Nylon layer is to ensure the appearance of aluminum laminate film,...

The battery cells of the pouch cell battery can be designed into different sizes according to the needs of customers.  When the pouch cell case size is well designed, it is necessary to make the corresponding mold to make the aluminum laminate film forming. The pouch cell case forming process is using the forming mold to punch out a pit on the aluminum laminate film that c...

After pouch cells top sealing and side sealing, need to do X-ray to check the alignment of the battery cells, then put the battery cells into the drying room for drying(you can also use the drying oven to drying the battery cells). After the battery cells drying process is completed, The next step is electrolyte filling process and primary sealing process. Through the introduction of the previous ...

Author: XIA Qiuying, SUN Shuo, ZAN Feng, XU Jing, XIA Hui School of Materials Science and Engineering, Nanjing University of Science and Technology, Nanjing 210094, China Abstract All-solid-state thin film lithium battery (TFLB) is regarded as the ideal power source for microelectronic devices. However, the relatively low ionic conductivity of amorphous solid-state electrolyte ...

Why are all-solid-state batteries an industry trend? High security: The safety issues of liquid batteries have always been criticized. The electrolyte is easily flammable under high temperature or severe impact. Under high current, lithium dendrites will also appear to pierce the separator and cause short circuit. Sometimes the electrolyte may undergo side reactions or decompose at high temperatur...

The dew point is the temperature at which moisture condenses. When the water vapor content in the air remains unchanged and the air pressure is kept constant, the temperature at which the air is cooled to saturation is called the dew point temperature (Td), or dew point for short. It can also be understood as the temperature at which water vapor and water reach equilibrium. The difference between ...
