Abstract:

The Cl-based aluminum-ion battery is a promising energy storage technology. The aluminum-ion battery is expected to become the next-generation energy storage system because of its high energy density, low price, and high safety. In this study, a rapid rechargeable low-temperature conductive carbon electrode paste was introduced, which was initially used in the screen printing technology of perovskite solar cells, can achieve rapid charge and discharge at a current density of 1000 mA/g, and exhibits specific capacities of 75 mAh/g. Its charging rate can reach 12 C. The performance of the aluminum-ion battery assembled with low-temperature conductive carbon electrode slurry, natural graphite flake, and graphene as cathode materials was compared and analyzed using optical microscopy, scanning electron microscopy, X-ray diffraction, and specific surface area analyses. It was found that the rapid charge-discharge was mainly due to its unique surface morphology and small specific surface area. The specific capacity of low-temperature conductive carbon electrode paste as a cathode material was also proved to be higher than that of other cathode materials by X-ray diffraction and other tests. This cathode material realized the aluminum-ion battery with high charge-discharge current density.

Key words: aluminum-ion battery, aluminum, graphite, low temperature conductive carbon electrode paste
