Liquid dispersions of quantum dot particles include an acrylic medium having a boiling point in a range of from greater than or equal to 100° C. to less than or equal to 500° C., quantum dot particles dispersed in the acrylic medium, a photo-initiator, and a surface additive. The liquid dispersions of quantum dot particles are useful as stable liquid formulations that resist gelling for spin-coating and ink-jet printing of color conversion layers in the manufacture of LED and micro-LED panels for advanced displays. Methods of manufacturing light-emitting devices using the liquid dispersions of quantum dot particles are also disclosed.

In this disclosure, we describe a new chemical treatment that can be performed on lithium metal and lithium alloy surfaces to selectively remove LiH defects. This treatment utilizes an exclusive reaction between LiH and trialkyl borane to form lithium borohydride complexes, which can be easily washed away from surface using an inert organic solvent. This treatment can be useful for lithium metal and lithium alloy anodes for high energy batteries.

A novel solid block copolymer electrolyte material is described. The material has first structural polymer blocks that make up a structural domain that has a modulus greater than 1&#xd7;10Pa at 25&#xb0; C. There are also second ionically-conductive polymer blocks and a salt that make up an ionically-conductive domain adjacent to the structural domain. Along with the second ionically-conductive polymers, there is also a crosslinked network of third polymers, which interpenetrates the ionically-conductive domain. The third polymers are miscible with the second polymers. It has been shown that the addition of such an interpenetrating, crosslinked polymer network to the ionically-conductive domain improves the mechanical properties of the block copolymer electrolyte with no sacrifice in ionic conductivity.

Syntheses of graft copolymers based on PEO and fluorinated functional groups are described. Grafting of fluorinated groups reduces the Tof PEO and also increases the miscibility of PEO with ionic liquids, so that addition of ionic liquids improves ionic conductivity even at room temperature.

Such copolymers can be used as either solid or gel electrolytes in Li batteries.
