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...

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...

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 ...

The development of electric vehicles is in full swing, and the power battery is one of the most important parts. Its development has a decisive effect on the battery life and safety of electric vehicles. Recently, we often hear some terms such as solid-state batteries, SVOLT’s jelly batteries, NIO’s Nickel 55 ternary Cell, IM Motors doped with silicon to supplement lithium, and CTP/CTC technology....

In recent years, there has been rapid development of sulfide solid electrolytes including Li2S-SiS2, Li2S-B2S3, Li2S-P2S5, Li(10±1)MP2S12(M=Ge, Si, Sn, Al, P),  Li6PS5X(X=Cl, Br, I). In particular, the thio-LISICON structure sulfide, represented by Li10GeP2S12 (LGPS), exhibits extremely high room temperature lithium ion conductivity of 12mS/cm exceeding that of liquid electrolytes, which has ...

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 ...
