Abstract: As a kind of building energy storage device, the novel cement-based battery has the advantages of low cost, environmental friendliness and rechargeability, and has been widely concerned by researchers at home and abroad. In this study, the electrode of a new cement-based rechargeable battery was made by mixing different conductive fillers with positive and negative active substances and grinding, and then drying by vacuum. And the effects of the kinds and content of the conductive fillers on the electrochemical property of the rechargeable cement-based batteries were investigated. The results show the cement-based battery with the mass fraction of 25% carbon black possesses a battery capacity of 12.5 mAh, an energy density of 1.575 Wh/m2, and the discharge lifespan exceeds 3.3 h, its electrochemical properties are better than that of graphite cement-based batteries and graphene cement-based batteries with the same mass fraction.

Key words: cement-based battery, rechargeability, building energy storage, conductive filler, electrochemical property
