Dew point
The temperature at which the water vapour in air would start to condense, the standard way of specifying dry-room humidity. A −40 °C dew point corresponds to about 0.5 % relative humidity at room temperature.

Example
Manufacturing: an example situation
An electrode can meet coating mass targets but fail adhesion or moisture checks later.
Read Dew point alongside Dry room in this context. A production room whose air is kept extremely dry — dew points around −30 °C to −60 °C — so that no moisture reaches the cell while the electrolyte goes in. Water would react with the salt LiPF₆ to form hydrofluoric acid.
Use in Lemonergy
