With increasing desires for superior electrochemical energy storage devices, metal-air batteries are the most dense electrochemical power sources and are anticipated to play an important role in electrification of transportation and grid energy storage. A major challenge in metal-air batteries, such as zinc-air and lithium-air batteries, is the overpotentials caused by the multi-electron chemical processes oxygen goes through in order to store and dispense energy. Since expensive catalysts are required to reduce these high overpotentials, these batteries are neither energy- nor cost-efficient.<\/p>\n<p><a href=\"https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/K-O2.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-848 size-medium\" src=\"https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/K-O2-300x171.png\" alt=\"K-O2\" width=\"300\" height=\"171\" srcset=\"https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/K-O2-300x171.png 300w, https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/K-O2-768x437.png 768w, https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/K-O2-1024x583.png 1024w, https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/K-O2.png 1500w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>In 2013, Wu group invented K-O<sub>2<\/sub> battery that is based on the reversible one-electron O<sub>2<\/sub>\/KO<sub>2<\/sub> redox couple, which eliminates the need for these electrocatalysts.

In 2014, his group demonstrated a solar oxygen battery that uses solar energy to assist the charging process of Li-O<sub>2<\/sub> batteries. Later the concept was extended to solar flow batteries that use solar energy to assist the charging process of Li-iodine flow batteries. These pioneering works are useful for creating new technology that can directly store the solar energy, which solves the intermittent nature of sunshine.
