Confining Liquid Electrolytes in a Nitrogen-Rich Nanoporous Carbon Sponge for Superior Lithium-Ion Conduction.

Solid-state Li-ion batteries are recognized as highly promising energy storage devices due to their ability to overcome issues related to the inferior cycle life and potential risks of traditional liquid Li-ion batteries. However, developing solid-state electrolytes with fast Li-ion conductivity continues to be a major challenge. In this study, we present a family of quasi-solid-state electrolytes (QSSEs) synthesized by confining liquid electrolytes within a N-rich porous carbon sponge, exhibiting superior Li-ion conduction for solid-state battery applications.

[A simulation facility for low temperature water surface environment].

Objective: To simulate the water environment during floating status after astronauts returned and splashed down on the sea because of space capsule emergency in the launching stage.

Method: Environmental temperature in the laboratory and water-temperature in the tank were auto-controlled individually according to heat charge calculation. To meet the need of maintaining the uniformity of water-temperature, the structure of the water circulation pipeline was specially designed to increase thread-conflux and laminar flow effect.
