Method and system for preparing graphite ceramics from recycled anode materials of waste lithium series batteries

Abstract

A method for recycling negative electrode materials from waste lithium-ion batteries and converting them into graphite ceramics involves physically decomposing the waste lithium-ion batteries and then obtaining the internal negative electrode materials through washing, dehydration, drying, and sieving. These negative electrode materials are essentially ordinary carbon powder, mostly artificial graphite with a carbon content of over 99%. The artificial graphite content is then adjusted and mixed with clay or porcelain clay at a certain ratio, such as 0.5% to 5%. The mixture is then shaped into various pottery items, such as cups, plates, bowls, ladles, basins, pots, urns, steamers, spoons, and other everyday edible ceramics. These are then fired into ceramic or pottery products. The firing methods can be high-temperature oxidation firing or high-temperature reduction firing, and can be carried out in electric kilns, gas kilns, wood-fired kilns, or microwave oven kilns. A method for preparing graphite ceramics from recycled anode materials of waste lithium series batteries involves the following steps: After physically decomposing the waste lithium series batteries, the internal anode materials are obtained through washing, dehydration, drying, and sieving. These anode materials are generally carbon powder, primarily consisting of artificial graphite with a carbon content exceeding 99%. By adjusting the artificial graphite content and mixing it in a proportion of 0.5% to 5% with ceramic clay and porcelain clay, the mixture is then shaped into various ceramic items such as cups, plates, bowls, ladles, basins, pots, urns, steaming vessels, and spoons. These items are then fired to produce ceramic or pottery products. The firing method can be high-temperature oxidation firing or high-temperature reduction firing, using electric kilns, gas kilns, wood kilns, or microwave kilns.
