The increasingly serious environmental problems and energy challenges have caused an urgent need for the development of green and efficient energy storage systems.Among various energy storage technologies,sodium-ion batteries(SIBs),potassium-ion batteries(PIBs),and especially lithium-ion batteries(LIBs),which have been commercialized,play a very important role in portable electronic devices or next-generation electric vehicles.Therefore,finding new electrode materials with lower cost,higher safety and higher density in these energy storage systems has become an important way to meet the growing demand.Symmetrical electrode has become a research focus in recent years because the same active material is used as the positive electrode and the negative electrode in the same energy storage system,which reduces the manufacturing cost and simplifies the manufacturing process.Most importantly,this feature also enables symmetric energy storage systems to have higher safety,longer service life and two-way charging capabilities.In this progress report,we provide a comprehensive summary and review of organic and inorganic symmetric electrodes,and focus on the application of symmetric electrodes in different energy storage systems,such as the SIBs,PIBs and LIBs mentioned above.Further consideration is given to the possibility of mass production.
