摘要:Olivine lithium transition metal phosphate cathode materials are made in a microwave-assisted process by combining precursors in a mixture of water and an alcoholic cosolvent, then exposing the precursors to microwave radiation 5 to heat them under superatmospheric pressure. This process allows rapid synthesis of the cathode materials, and produces cathode materials that have high specific capacities.

摘要:The present application relates to the technical field of batteries, and relates to an oxalate material, a preparation method, a use, a lithium-ion battery cathode material and a lithium-ion battery. The oxalate material of the present application comprises the following chemical compositions: Li2TMC4O8, wherein TM is a transition metal having charge of plus two. The oxalate material is a polyanionic-based cathode material having dual electrochemical activities and can be used as a lithium-ion battery cathode active material in a lithium-ion battery. With respect to existing lithium-ion battery cathode materials, the present application provides a designing and preparation method for a cathode material having a good safety and high capability. Besides, the synthesis method for the cathode active material is convenient, rapid and safe and all materials are cheap and easily obtained; and the cathode active material is important for optimizing battery material synthesis technique and reducing electrode material preparation cost.
