Description

technical field [0001] The invention relates to a novel semi-solid sodium-air battery and a preparation method thereof, belonging to the technical field of electrochemistry. Background technique [0002] With the rapid development of society and the increasing global demand for fossil fuel resources, the shortage of traditional fossil energy and the damage to the environment caused by over-exploitation have become major problems restricting the sustainable development of my country and the global economy. In order to promote the optimization and upgrading of the energy industry and achieve clean and low-carbon development, in recent years, my country has vigorously developed clean energy, wind power and photovoltaics have achieved leapfrog development, and the proportion of installed capacity of new energy has increased day by day. However, with the rapid development of clean energy, the grid-connection of fluctuating and intermittent new energy has brought adverse effects o...
