| titleOfInvention | Method for manufacturing lithium iron phosphate all-solid-state film cell by in-situ spray pyrolysis |
| abstract | The invention discloses a method for manufacturing a lithium iron phosphate all-solid-state film cell by in-situ spray pyrolysis. The method is characterized in that an in-situ spray pyrolysis technology is adopted; a slightly excess amount of a nonvolatile high-boiling point organic polymer is added into an anode precursor solution so that in a spray process, the anode precursor solution and anode active substances are mixed well; in follow-up heat treatment, a cracking process is carried out in the air-free environment and ferric iron is reduced in situ by carbon obtained by the cracking process so that the lithium iron phosphate all-solid-state film cell is obtained; after in-situ reduction, a trace amount of carbon is utilized as an electronic link of an anode material so that electronic conductivity of the anode material is improved; and in the spray process, through a spray gun, two buffer layers are formed at junction parts of an anode layer, a solid electrolyte layer and a cathode layer and phase composition of each adjacent two of the anode layer, the solid electrolyte layer and the cathode layer continuously changes in the buffer layers. Through the method provided by the invention, adjacent layers are bonded closely; a layer-to-layer matching degree is greatly improved; stress and a crystal boundary are reduced; interfacial conductance is improved; the influences of interfacial conductance on cell integral performances are greatly reduced; and cell stability is improved. |
