Composite Cathodes
Posted by Chia-yu Chen on
Solid state electrolytes (SSEs) have attracted significant attentions. Compared to conventional liquid electrolytes for lithium-ion batteries, SSEs can eliminate most safety issues by avoiding the use of flammable organic chemicals. One of the major challenges of SSEs is the high interfacial resistance. The interfacial contact between SSE and an electrode will be further deteriorated during the expansion and shrinkage of the electrode during cycling. To reduce the resistance, it is critical to create ionic conduction pathways between solid electrolytes and electrodes interface as well as reduce the stress at the interface caused by expansion during charging and discharging. Using composite...

How to Fabricate Pouch Cells ? (Lab Line)
Posted by Chia-yu Chen on
Pouch cell fabrication involves several steps: Slurry preparation --> Slurry coating --> Calendaring --> Cut electrode --> Electrode stacking --> Weld current collectors and then tab together --> Produce a pouch case --> Top & side sealing --> Electrolyte filling --> Primary sealing (vacuum standing and vacuum seal) --> Battery formation (Charge/discharge) --> Degassing à Secondary sealing. MSE PRO battery fabrication equipment includes a wide range of production machines from slurry making to final sealing system. The flow chart below is the typical process for equipment that will be used for a R & D lab. Pouch Cell Fabrication Process Flow Slurry Making Vacuum Oven Vacuum Mixer Coating Film...
