摘要： Systems and methods are described for producing lithium hydroxide from lithium chloride and sodium chloride through an electrolysis process. A solution of lithium hydroxide and sodium hydroxide may be produced through electrolysis of a lithium chloride and sodium chloride solution. Lithium hydroxide in the produced solution may then be crystallized and filtered out to produce substantially pure lithium hydroxide crystals.

摘要： An electrochemical system and process are provided to convert an amount of chalcopyrite (CuFeS2) to a product including copper ions. In an electrochemical reactor, a potential is applied across an anode and a cathode to convert the chalcopyrite to an intermediate, chalcocite (Cu2S). The anode is covered to prevent contact with the intermediate, thus limiting subsequent conversion of the intermediate to covellite (CuS) in favor of conversion to a material more suited to chemical oxidation, cuprite (Cu2O). For example, the anode can be covered with one or more layers of filter paper. Upon application of an oxidizing agent, the cuprite is oxidized to produce a product including copper ions. The cathode and covered anode allow for efficient and inexpensive processing. The cost of this technique is comparable to industry standards, and moreover, has a much smaller environmental footprint than heat-based copper extraction.

The electrode structure includes one or more layers of fused and approximately aligned elongated electrocatalyst nanoparticles that include a non-noble metal alloy or non-noble metal compound. Anisotropic nanochannels are positioned between the fused and approximately aligned elongated electrocatalyst nanoparticles that are configured to transfer generated gas bubbles therethrough. The elongated electrocatalyst nanoparticles may be nanorods that may have a diameter of approximately 20 to 50 nanometers and a length of approximately 80 to 300 nanometers. The anisotropic nanochannels may have a channel width of approximately 50-150 nanometers. The non-noble metal may be one or more of iron, cobalt, nickel, copper, molybdenum, or tungsten. The one or more layers of fused and approximately aligned elongated electrocatalyst nanoparticles may be 3-D printed elongated electrocatalyst nanoparticles, and each layer has a thickness of approximately 50 to 200 microns.
