The bipolar stacking design minimizes inactive material in the batteries resulting in a significantly increased energy density. Moreover, since the batteries are connected in series, a high voltage output is obtained. Also, the shortened electron conduction paths between cells benefit lower resistance and increased power density.
Further, the double-layered device showed a capacity retention of 99% on the 200th cycle at 0.5 C, which is an indication of good cycling properties. These results suggest that bipolar stacked batteries with a quasi-solid-state electrolyte containing a Li-Glyme complex could readily produce a high voltage of 10 V.
Bipolar all-solid-state batteries (ASSBs) represent an emerging battery architecture and have attracted considerable interest due to their potential for high energy density, enhanced safety, and simplified packaging.
Bipolar-stacked electrode coupling with solid-state electrolytes enables achieving batteries with high output voltage, high energy density, and simple components.
