CAN: Big Glove Box with Safety Disk

Award outcome

Description

The National Physical Laboratory (NPL) requirement is for a glovebox dedicated to Lithium-ion cell and electrode fabrication. The purpose is to safely assemble pouch cells and coin cells as well as air sensitive electrode laminates, in an environment that prevents contamination by atmospheric pollutants as well as Oxygen, Nitrogen, and moisture. The setup needs to be able to work in presence of metallic lithium, and other alkali and alkaline earth metal electrodes. Therefore, Argon must be used to fill the glovebox rather than Nitrogen, and a Nitrogen filter needs to be provided in order to preserve the integrity of the electrodes and internal components of the cells. The asset must enable the safe production of electrodes and pouch and coin cell assembly on the following requirements: 1) The equipment should provide a contained environment spacious enough for small scale electrode and cell fabrication equipment. 2) The equipment should be equipped with a disk burst with predetermined breaking points in order to prevent overpressure in the box in case of battery thermal runaway. 3) The equipment should be equipped with oxygen, moisture, and nitrogen sensors in order to ensure the quality of the atmosphere. 4) The equipment should be equipped with a purging system. 5) The equipment should be equipped with a solvent trap. 6) The equipment should be equipped with a Nitrogen filter. 7) The equipment should be equipped with a small side-mounted fridge for the safe storage of small amounts of chemicals.
