Preparation of cathode materials for Li-ion cells by acid dissolution

摘要: Abstract New synthesis route called acid dissolution method, preparing the high-performance cathode materials for lithium-ion cells, was successfully developed. In this insoluble starting such as metal carbonates or hydroxides are dissolved in strong organic acidic solution which contains a chelating agent. And then, solvent of containing is eliminated to obtain xerogel initial whose chemical form expressed Li[MA 3 ], where M transition atom and A anion acid. The then calcined at high temperature polycrystalline materials. work, applicability method demonstrated synthesizing single-phase LiCoO 2 using lithium carbonate, cobalt hydroxide acrylic synthesized powders 800 °C showed good electrochemical performance half-cell test.
