Abstract: Prelithiation solutions for lithium-based electrochemical cells are provided. The prelithiam solutions include prelithiation salts that are configured to prelithiate the negative electrode of the electrochemical cell. Lithium ions from the prelithiation lithium salt prelithiate the negative electrode when a charging current is passed between the negative and positive electrodes. In some embodiments, the prelithiation solution may function as an electrolyte for the electrochemical cell and further includes an ion conducting lithium-based salt that is stable at the cell operating voltage. Also provided are methods of prelithiation and electrochemical cells including prelithiation solutions.

Abstract: Disclosed herein are fluorescent polysiloxanes and methods of making them. Fluorescent aryl alcohols or fluorescent aryl carbinols are reacted with hydropolysiloxanes in the presence of a catalyst to link the fluorescent groups to the polysiloxane chain through an ether linkage. The resulting compounds are fluorescent and have other desirable properties.
