Abstract: Disclosed are a multilayer composite electrode sheet, an energy storage apparatus and a preparation method. A positive current collector, a first lithium manganese iron phosphate layer, a second lithium manganese iron phosphate layer, a third lithium manganese iron phosphate layer are sequentially formed. One end of a first conductive fiber is inserted obliquely into the surface of the first lithium manganese iron phosphate layer on the one side and the other end is inserted obliquely into a surface of the second lithium manganese iron phosphate layer on one side. One end of a second conductive fiber is inserted obliquely into the surface of the second lithium manganese iron phosphate layer facing away from the positive current collector and the other end is inserted obliquely into a surface of the third lithium manganese iron phosphate layer facing toward the positive current collector.
