Science Daily  July 25, 2022 Alkaline Zn batteries have limited rechargeability. The short cycle life is caused by the transition between metallic Zn and ZnO, whose differences in electronic conductivity, chemical reactivity, and morphology undermine uniform electrochemical reactions and electrode structural stability. To address this an international team of researchers (Hong Kong, USA- Georgia Institute of Technology, China) has proposed an electrode design with bi-continuous metallic zinc nanoporous structures capable of stabilizing the electrochemical transition between metallic Zn and ZnO. Via in situ optical microscopy and electrochemical impedance measurements, they demonstrated the kinetics-controlled structural evolution of Zn and ZnO. In […]
