Abstract: Developing energy storage devices and new materials, which match the requirements in electric vehicles (EVs) and hybrid electric vehicles (HEVs), is an effective way to balance the contradiction between the social development and the shortage of fossil energy and environment pollution. Rechargeable lithium-air (Li-air) batteries consisting of Li and oxygen as the anodic and cathodic reactants, respectively, have attracted much attention during the past decade due to their high theoretical specific energy. According to work conditions, the most studied types of Li-air batteries are non-aqueous, hybrid, and solid state electrolyte Li-air batteries. Challenges still exist in cathodes, anodes, electrolytes and performances (life time), though efforts have been dedicated during the past years. Based on the achievements in non-aqueous and hybrid Li-air batteries from our group, the history, research progress and future developing trend of Li-air batteries will be briefly introduced in this review.

Key words: non-aqueous electrolyte, hybrid electrolyte, Li-air batteries
