Lithium exposed to air
Webexposed to air from 5min to 10 d (50% relative humidity). We can observe that the float, which are 30 and 45 V samples have a similar evolution with a fast increase in density for the first 400 min, followed by a slow increase to reach a plateau around 1g 3cm . This evolution of the density indicates that lithium rapidly reacts with air in the WebMechanic II. Date Posted: 4/12/2024. Application Deadline: Until Filled. Employment Type: Full Time.
