Abstract: A process for recovering a nickel cobalt manganese hydroxide from recycled lithium-ion battery (LIB) material such as black mass, black powder, filter cake, or the like. The recycled LIB material is mixed with water and either sulfuric acid or hydrochloric acid at a pH less than 2. Cobalt, nickel, and manganese oxides from the recycled lithium-ion battery material dissolve into the acidic water with the reductive assistance of gaseous sulfur dioxide. Anode carbon is filtered from the acidic water, leaving the dissolved cobalt, nickel, and manganese oxides in a filtrate. The filtrate is mixed with aqueous sodium hydroxide at a pH greater than 8. Nickel cobalt manganese hydroxide precipitates from the filtrate. The nickel cobalt manganese hydroxide is filtered from the filtrate and dried. The filtrate may be treated ammonium fluoride or ammonium bifluoride to precipitate lithium fluoride from the filtrate. The composition ratio of nickel to cobalt to manganese in the acid filtrate may be adjusted to a desired ratio. The anode carbon is recovered and purified for reuse.

Abstract: A connectorized lighting system for a base structure such as a deck pad, comprising a base structure having an a retaining cavity disposed in and running along a surface of the base structure, a lighting element inserted into the retaining cavity, and connectorized light source that provides electrical power to the lighting element, exhibits a low profile, and may be removable and replaceable without tools. The base structure may be a deck pad on a boat or a covering for a floor, spa, spa cabinet, pool, or any other surface. The deck may comprise EVA or PE foam material, and may comprise one or more layers of sheet material. The retaining cavity may comprise a window and bevels for visibility. A lighting element may be held in place by forces created when the compressible material of the base structure is compressed by pressing the lighting element into the retaining cavity.
