POSITIVE ELECTRODE FOR RECHARGEABLE LITHIUM ION BATTERY, RECHARGEABLE LITHIUM ION BATTERY, AND BATTERY MODULE

摘要

A positive electrode for a rechargeable lithium ion battery includes a mixture layer including a positive-electrode active material, a conducting agent, and a binder and a collector having the mixture layer formed on the surface thereof. The positive-electrode active material is a composite oxide having an olivine structure expressed by a formula LiaMxPO4 (where M represents a transition metal including at least one of Fe and Mn and a and x satisfy 0
