Container for nonaqueous electrolyte solution nonaqueous electrolyte solution to put in container and method for storing nonaqueous electrolyte solution

摘要

The present invention is a (1) container for nonaqueous electrolyte solutions constituted of a material that contains aluminum or an aluminum alloy layer and is a container that is filled with a nonaqueous electrolyte solution formed by dissolving and electrolyte salt in a nonaqueous solvent. The container has a resin cap and a intermediate plug and the water content of a nonaqueous electrolyte after 30 days of storage in the container is maintained at 50 ppm or less. The present invention is also (2) a nonaqueous electrolyte solution to be put in the container and (3) a method for storing nonaqueous electrolyte solutions. This container for nonaqueous electrolyte solutions prevents decomposition of the nonaqueous electrolyte solution during storage preserves high quality and is a lightweight container capable of easily and assuredly handling nonaqueous electrolyte solutions.
