Honeycomb type lithium ion battery

A honeycomb type lithium ion battery having an anode, a cathode, and a separator layer,

• wherein the anode has a plurality of through holes extending in one direction,
• the separator layer has Li ion permeability, physically isolates the anode and the cathode from each other, and has partition separator layers and insulating film separator layers, insides of the through holes being covered with the partition separator layers, opening face parts on one and another sides of the through holes being covered with the insulating film separator layers,
• the cathode has inner areas disposed inside the through holes via the partition separator layers, intermediate areas disposed over faces of the inner areas and faces of the insulating film separator layers, and a surface area with which surfaces of the insulating film separator layers and the intermediate areas are covered, and
• the cathode contains a binder, wherein a proportion of a content of the binder in the surface area is 2 wt % or more and 5 wt % or less, and a proportion of a content of the binder in the inner areas is 1 wt % or less.
