Artificially engineered, bicontinuous anion-conducting/-repelling polymeric phases as a selective ion transport channel for rechargeable zinc-air battery separator membranes
Zinc (Zn)-air batteries have recently attracted a great deal of attention as a promising energy storage system to fulfill our ever-increasing demand for higher energy density power sources.

Despite commercial success of primary Zn-air batteries, performances of rechargeable Zn-air batteries are still far below practically satisfactory levels.
