摘要： A sodium-halogen secondary cell that includes a negative electrode compartment housing a negative, sodium-based electrode and a positive electrode compartment housing a current collector disposed in a liquid positive electrode solution. The liquid positive electrode solution includes a halogen and/or a halide. The cell includes a sodium ion conductive electrolyte membrane that separates the negative electrode from the liquid positive electrode solution. Although in some cases, the negative sodium-based electrode is molten during cell operation, in other cases, the negative electrode includes a sodium electrode or a sodium intercalation carbon electrode that is solid during operation.

摘要： An improved gas diffusion electrode composed of a perovskite-type oxide dispersed in a mixture of carbon black and a hydrophobic binder polymer. An improved catalyst for use in the electrochemical reduction of oxygen comprising a perovskite-type compound having alpha and beta sites, and having a greater molar ratio of cations at the beta site. A particularly good reduction catalyst is a neodymium calcium manganite. An improved method of dispersing the catalysts with carbon in a reaction layer of the electrode improves performance of the electrode and the oxygen reduction process. This is provided by adding carbon black to an aqueous solution of metal salts before it is heated to a gel and then to a char and then calcined. Optionally, a quantity of the desired oxide catalyst can be premixed with a portion the carbon before adding the carbon to an aqueous solution of the metal salts to be heated. The amount of premixed metal oxide is chosen in conjunction with the amount of metal salts to provide the desired molar ratio after heating and calcining of the aqueous solution.
摘要翻译：改进的气体扩散电极，其由分散在炭黑和疏水性粘合剂聚合物的混合物中的钙钛矿型氧化物组成。用于电化学还原氧的改进的催化剂包括具有α和β位点的钙钛矿型化合物，并且在β位具有更大的阳离子摩尔比。特别好的还原催化剂是钕钙锰矿。将电催化剂用碳分散在电极的反应层中的改进方法提高了电极的性能和氧还原过程。这是通过在金属盐的水溶液加热至凝胶然后加入炭然后煅烧之前将炭黑加入到水溶液中而提供的。任选地，一定量的所需氧化物催化剂可以在将碳添加到待加热的金属盐的水溶液中之前与碳的一部分预混合。联合金属盐的量选择预混合金属氧化物的量，以便在加热和煅烧水溶液之后提供所需的摩尔比。
