Latest Patents

One of Swoffer's latest innovations involves a novel process for recycling cobalt and nickel from lithium-ion batteries. This method enables the recovery of nickel cobalt manganese hydroxide from recycled LIB materials, including black mass, black powder, and filter cake. The process begins by mixing recycled LIB material with water and either sulfuric or hydrochloric acid at a pH of less than 2. Through the use of gaseous sulfur dioxide, cobalt, nickel, and manganese oxides dissolve into the acidic solution. The anode carbon is then filtered, leaving a solution rich in essential metal oxides.

Following this, the filtrate is mixed with aqueous sodium hydroxide at a pH greater than 8, facilitating the precipitation of nickel cobalt manganese hydroxide. The precipitate is subsequently filtered and dried for further use. Additionally, the process allows for the recovery and purification of anode carbon for reuse, as well as the potential treatment of the filtrate with ammonium fluoride or ammonium bifluoride to precipitate lithium fluoride, enhancing the versatility of his method.
