Insight
Solid-state batteries and liquid batteries have many similarities in the manufacturing process, such as the manufacturing process of electrode lugs are based on slurry mixing, coating and expansion, slitting is completed after the lug welding, PACK (battery pack processing into groups), the most important difference has three points,
1) solid-state batteries composite cathode material, ie, a mixture of solid-state electrolyte and cathode active material as a composite cathode;
2) electrolyte additive The way is different, the liquid battery is in the pole ear welding after the electrolyte into the battery and encapsulation, while the solid-state electrolyte in addition to the formation of composite anode with the cathode active material, but also need to be in the extension of the completion of the composite cathode and then a coating;
3) liquid lithium-ion battery electrode can be used to roll or stacked piece of the combination of the way, while the solid-state battery due to its solid-state electrolyte such as oxides and sulfides toughness is poor, usually encapsulated in the form of stacked wafers.
