We report the synthesis and characterization of various compounds containing 1,7,9-hydroxylated closo-dodecahydrododecaborate (B12H9(OH)32-) cluster motif. Specifically, we show how the parent compound can be synthesized on the multigram scale and fu

This work demonstrates the first successful electrochemical cycling of a redox-active boron cluster-based material in the solid state. Specifically, we designed and synthesized an ether-functionalized dodecaborate cluster, B12(OCH3)12, which is the s

Conventional cathodes for Li-ion batteries (LIBs) are reaching their theoretical capacity limits. One way to meet the growing demands for high-capacity LIBs is by developing so-called Li-rich cathode materials that greatly benefit from additional cap

We report on the reversible, electrochemical (de)fluorination of CsMnFeF6 at room temperature using a liquid electrolyte. CsMnFeF6 was synthesized via three methods (hydrothermal, ceramic, and mechanochemical), each of which yields products in a defe

The performance of the sulfur-carbon composite cathode in a lithium-sulfur battery is chiefly determined by the nature of the carbon materials, the total sulfur content, and the distribution of sulfur within the composite electrode. Despite years of

Lithium-Sulfur batteries are promising as the next-generation of low-cost, high-energy rechargeable batteries. However, the commercialization of this battery has been limited by poor rate capability and cycle life. To improve the performance of Li-S

The polymer binders used in most lithium-ion batteries (LIBs) serve only a structural role, but there are exciting opportunities to increase performance by using polymers with combined electronic and ionic conductivity. To this end, here we examine d
