A barrier metal is a material used in integrated circuits to chemically isolate semiconductors from soft metal interconnects, while maintaining an electrical connection between them. For instance, a layer of barrier metal must surround every copper interconnect in modern integrated circuits, to prevent diffusion of copper into surrounding ...
As of 2020, Albemarle was the largest provider of lithium for electric vehicle batteries in the world. [3] Albemarle, Sociedad Química y Minera, and FMC Corporation collectively produce just over half of the world's lithium and lithium storage products, while just under half is produced by China.

Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
Metal barriers are used to encase the copper interconnects used in modern integrated circuits to avoid diffusion of Cu into the surrounding materials, such as insulators and the silicon substrate, and also, to prevent Cu contamination by elements diffusing from the insulators by surrounding every Cu interconnect with a layer of metal barriers ...

This is largely due to the use of lithium metal anodes, which have a much higher charge capacity than the graphite anodes used in lithium-ion batteries. At a cell level, lithium-ion energy densities are generally below 300Wh/kg while solid-state battery energy densities are able to exceed 350 Wh/kg. [ 117 ]
Texas Lt. Gov. Dan Patrick said U.S.-owned border wall materials, which were available for sale, were pulled from an Arizona auction at the government's request. The Lonestar State had shown ...
