Abstract：

Researches　about　renewable　rechargeable　battery　have　attracted　the　attention　of　many　scholars,　due　to　increasing　demands　of　energy　and　global　energy　crisis.　Zinc-air　batteries　are　one　of　most　promising　energy　sources,　but　the　morphological　changes　and　forming　dendritic　of　zinc　anodes　greatly　limit　their　cycle　life　during　the　charging-discharging　process.　In　order　to　improve　zinc-air　batteries　electrochemical　performance　and　control　dendritic　growth,　surface　of　zinc　anodes　is　irradiated　by　femtosecond　laser　with　different　power.　The　electrochemical　results　indicate　that　zinc　anodes　of　zinc-air　batteries　with　different　surface　structures　show　different　electrochemical　properties.　Due　to　the　removing　oxide　layer　on　the　surface　of　zinc　anode,　adding　contact　areas　of　zinc　anodes　and　electrolytes,　and　restraining　dendritic　growth　by　femtosecond　laser　processing,　first　discharge　time　of　zinc　anodes　with　surface　structures　of　zinc-air　batteries　is　about　10　times　than　that　of　without　processing.　It　is　also　found　that　more　intense　chemical　reactions　occur　in　the　area　treated　by　femtosecond　laser.　©　The　Authors,　published　by　EDP　Sciences,　2021.
