Lithium-ion batteries are the cornerstone of electric mobility and represent the best alternative for the industry to date, since they are able to store more charge per unit mass than other types of batteries and make it possible for vehicles and devices to have a certain amount of range.
Perhaps not everyone knows that producing them requires certain processes to be carried out in a vacuum. From drying, filling, degassing to sealing: without vacuum, many steps would not be possible.
For example, the initial mixing process of the amalgam with lithium-metal oxides, binders, and solvents takes place under vacuum, which prevents air from entering and ensures a pure and well-blended mix.
The battery is then subjected to vacuum to ensure there is no moisture or residual air.
Next, the filling of the electrolyte also takes place under vacuum for even distribution of the electrolyte within the cells.
Finally, degassing of the electrolytes takes place under vacuum to eliminate air bubbles, so the lithium ions can move freely, enabling optimal charging and discharging of the battery.
