高性能非水性体系锂空气电池研究进展

Research Progress on High Performance Non-aqueous Lithium-air Batteries

摘要:

随着清洁能源革命的到来，以电能代替燃汽驱动汽车行驶的方式已渐渐进入人们的视野。目前电动汽车使用的锂离子电池受制于其理论比能量较低，其连续行驶距离远低于内燃机动力汽车所能达到的距离。与锂离子电池不同，锂空气电池具有极高的理论比能量，有望取代锂离子电池成为电动汽车行业的核心技术。故本文综述了近几年锂空气电池在反应机理、非水性电解液和空气正极3个方面的最新研究进展，并展望了其未来的发展趋势

Abstract:

With the coming of the Clean Energy Revolution, using electric energy to power cars instead of gasoline has gradually come into the view of the public. Currently, electric cars employ lithium ion battery, but, limited by its theoretical specific energy, the endurance of these cars is far less than cars with internal combustion engines. Lithium-air battery, different from lithium ion battery, enjoys very high theoretical specific energy and is looking to replace lithium ion battery and becomes the core technology of electric car industry. Therefore, this paper summarizes the latest research and development of lithium-air battery in reaction mechanism, non-aqueous electrolyte, and air electrode, and gets a view of its future development
