AB Today’s society relies on energy storage on a day-to-day basis, e.g. match energy production and demand from renewable sources, power a variety of electronics, andenable emerging technologies. As a result, a vast range of energy storage technologies has emerged in the last decades. Among them, rechargeable Zn–Air batterieshave held great promises for a long time. However, the severe challenges related to the reversible O2 reactions and poor cyclability at the positive and negativeelectrodes, respectively, have severely hindered the success of this technology. Herein, electrically-conducting and semi-flowable Zn semi-solid electrodes areproposed to revive the appealing concept of a mechanically–rechargeable alkaline Zn–Air battery, in which the spent negative electrodes are easily substituted at theend of the discharge process (refillable primary battery). In this proof-of-concept study energy densities of ca. 1500 Wh L− 1 (1350 Ah L− 1electrode and utilization rate of85%) are achieved thanks to the compromised flowability of the proposed Zn semi-solid electrodes. In this way, semi-solid Zn electrodes become a type of greenenergy carrier having intrinsic advantages over gas and liquid fuels. Zn semi-flowable electrode can be generated elsewhere using renewable sources, easily stored,transported, and used to produce electricity.
