英文摘要：

The applications of molten salts in electrolyte cell （including fuel cell, lithium battery and thermal battery）, solar thermal power generation and biomass pyrolysis are reviewed. The working characteristics, conversion efficiency and service life of fuel cells with molten salts are evaluated. It is also pointed out that the development of fuel cells will focus on molten carbonate fuel cells. Compared with the cathode material of lithium battery, prepared by high temperature solid phase method, the material by molten salt method is improved on crystalline structure and performance. And in solar thermal power generation field, high temperature molten salt as a low cost and high efficiency heat transfer and storage medium has been also applied. FtLrthermore, recent research progress in pyrolysis of biomass to bio-oil or hydrogen-rich gas in molten salt media is summarized. By examining molten salt composition and reaction temperature, and referring pyrolysis mechanism and kinetics, it is concluded that pyrolysis of biomass in molten salts is practicable. Finally, in order to enhance the development of molten salts application forward, problems to be solved are listed.
