Seed Layer Formation on Carbon Electrodes to Control LiO Discharge Products for Practical Li-O Batteries with High Energy Density and Reversibility.

The high theoretical energy densities of lithium-air batteries (LAB) make this technology an attractive energy storage system for future mobility applications. LiO growth process on the cathode relies on the surrounding chemical environment of electrolytes. Low conductivity and strong reactivity of LiO discharge products can cause overpotential and induce side reactions in LABs, respectively, eventually leading to poor cyclability.

Graphitic Hollow Nanocarbon as a Promising Conducting Agent for Solid-State Lithium Batteries.

All-solid-state batteries (ASSBs) have lately received enormous attention for electric vehicle applications because of their exceptional stability by engaging all-solidified cell components. However, there are many formidable hurdles such as low ionic conductivity, interface instability, and difficulty in the manufacturing process, for its practical use. Recently, carbon, one of the representative conducting agents, turns out to largely participate in side reactions with the solid electrolyte, which finally leads to the formation of insulating side products at the interface.
