以LiOH·H2O和LiNO3为原料，采用溶液湿化学法在500℃的中温条件下合成了Li4SiO4粉末。本文研究和比较了LiOH·H2O和LiNO3两种原料制得的粉末的物相演化行为、比表面积和形貌。讨论并论证了用这种化学方法合成Li4SiO4-LiNi0.75Co0.25O2基电解液-电极复合材料的可行性。
A solution based wet chemistry approach has been developed for synthesizing Li4SiO4powders at moderate temperatures of 500°C. LiOH·H2O and LiNO3have been used as starting materials for synthesizing this material in the present study. The phase evolution behavior, surface area and morphology of the as-prepared and heat treated powders generated from both LiOH·H2O and LiNO3have been studied and compared in this work. The feasibility of synthesizing a Li4SiO4LiNi0.75Co0.25O2based electrolyte–electrode composite material using this chemical approach is also discussed and demonstrated.
