摘要： In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

摘要： Gas diffusion electrode suitable for use in carbon dioxide electrolyzer and methods for making the same. According to one embodiment, the gas diffusion electrode may include a gas diffusion layer and a catalyst layer coupled to the gas diffusion layer. The gas diffusion layer, in turn, may include an electron-conductive domain and a non-conductive hydrophobic domain. The electron-conductive domain includes a plurality of pores. The non-conductive hydrophobic domain randomly occupies a portion of the volume of the pores of the electron-conductive domain and is, itself, sufficiently porous to permit gas transport through the electron-conductive domain, for example, by incompletely filling the pores, thereby leaving spaces in the pores, and/or by being made of an inherently porous material. The electron-conductive domain may be in the form of a metal mesh, a carbon paper, or similar structures. The non-conductive hydrophobic domain may be in the form of sintered polymer particles.
