This abstract first appeared for US patent application 20250015347 titled 'SECONDARY BATTERY

Original Abstract Submitted

a secondary battery includes a positive electrode, a negative electrode, an electrolyte layer, and a shut layer. the electrolyte layer is made of an electrolyte material having lithium ion conductivity. the shut layer contains a lithium ion conductive solid material having lithium ion conductivity. the electrolyte layer is interposed between the negative electrode and the shut layer. the shut layer is made of only a lithium ion conductive solid material or a mixture of the lithium ion conductive solid material. the lithium ion conductive solid material is at least one of a pyrochlore solid electrolyte, a nasicon solid electrolyte, and a perovskite solid electrolyte. the lithium ion conductive solid material has a larger decrease in lithium ion conductivity when in contact with lithium metal than the electrolyte material.
