Development of aqueous rechargeable batteries has been forced owing to safety issue of current Li rechargeable batteries. Multi-valent Zn-ion batteries have been emerged as promising candidate of the Li-ion batteries alternatives because of its abundance, safety, and electrochemical property. Zn-ion chemistry have been successfully commercialized as primary batteries for ear-aid power source applications, but dendrite formation on zinc anodes during charging prevents enough cycling performances of zinc rechargeable batteries. Unregulated ionic deposition on Zn anode surface due to nonselective ion transport has been recognized as the most critical cause of dendrite formation. Thus, cationic selective ion-exchange membrane can be the best option for regulating ionic deposition behavior to improve cyclability. In this presentation, a low cost cationic selective ion-exchange membrane for dendrite suppression will be thoroughly introduced. |
