Abstract

In nowadays, in response to current market having the high requirement and application level for lithium-ion batteries, the demands of lithium carbonate are rising increasingly. Now, lithium carbonate are mainly used in the glass and ceramics manufacture process as fluxing agent, additive agent and also used as preparation of various lithium compound. With the current research and development, high-purity lithium carbonate which purity over than 99.9% are applied to preparation of lithium-ion batteries cathode material and electrolyte raw material. In the aim of achieving material recycling, in this study, we will focus on recovery of lithium which is leached in sulfuric acid and trying to prepare lithium carbonate by chemical precipitation and promote it’s purity to obtain high-purity lithium carbonate. Finally, high-purity lithium carbonate can be used to preparation of lithium-ion batteries again.
