In article 1701082 , Yongbing Tang and co‐workers report a new configuration for Ca‐ion batteries. They construct a dual‐carbon battery in a Ca‐ion‐based organic electrolyte (Ca‐DCB) and show that the battery can work reversibly at room temperature with a high working voltage of up to 4.6 V. The reported Ca‐DCB exhibits good cycling stability for over 300 cycles with a high capacity retention of 94%.
