Abstract: Disclosed are a pin assembly for providing current to an electrode, e.g. an inert or oxygen evolving anode, and its manufacturing method. The pin assembly is configured to be inserted into an electrode body of an electrode for providing an electric current to the electrode body. The pin assembly comprises a structural support member configured to mechanically support the electrode body, and a protective conductive member configured to embed the structural support member. The protective conductive member comprises at least one metal or alloy thereof adapted for conducting the electric current while protecting the structural support member against corrosion during a given period of time of use of the electrode. The pin assembly enables convenient electrical connection of the electrodes, combines electrical and thermal performance for optimizing cell efficiency, provides structural and corrosion durability for extending pin assembly life, and utilizes robust joining processes for high reliability.

Abstract: The presently disclosed concepts relate to ultra-efficient EV battery recycling systems. Alkali metal extraction (and in particular lithium extraction) is accomplished using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metals, in particular lithium can be (energy-wise) efficiently separated from feed solutions. The energy used to initially extract lithium from a feed solution is stored as electrochemical energy, which electrochemical energy is reclaimed in subsequent extraction processing steps. This energy storage and energy reclamation is performed in continuous ultra-efficient ongoing cycles. Since irrecoverable energy losses incurred in each cycle are limited to negligible amounts of joule heating of the system components and feed solution, the system can be sustainably powered using locally-generated renewable energy.

Abstract: 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.
