Nanocellulose composite gel with high ionic conductivity and long service life for flexible zinc-air battery

Zinc-air batteries with high theoretical energy density have gained tremendous research interest as one of the candidate energy storage devices for flexible and portable electronic devices. Improving the performance of solid-state batteries (such as work stability, service life, etc.) has become a s...
