摘要： A lithium ion secondary battery which can keep an electric connection between active material layers and separators without using a strong case, which can be formed to any shape such as the one with a high energy density or a small thickness, and which has an excellent charging and discharging characteristic and has a large capacity for cell. Positive and negative active material particles are joined to a positive and a negative collectors respectively using binder resin to form a positive pole and a negative pole. Positive and negative active material layers and separators are so joined with binder resin that the junction strength between the separator and the positive active material layer, and between the separator and the negative active material layer, may be at least the same as that between the positive collector and the positive active material layer, and between the negative collector and the negative active material layer, to form a flat multilayer battery body with a plurality of electrode laminates. Electric connection between the electrodes can be obtained by keeping an electrolytic solution including lithium ions in spaces between the positive active material layers and the separators, and between the negative active material layers and the separators.

摘要： In a conventional lithium ion secondary battery using an electrolyte solution, a rigid armor can must be used for maintaining electric connection between electrodes, thus raising a problem that miniaturization cannot be realized. This problem is solved by the process for manufacture of a lithium ion secondary battery which is thin and light-weight and may have an arbitrary shape without using any armor can. When the lithium ion secondary battery is to be constituted by adhering an electrode and a separator using a binder resin containing a fluorine-based resin or polyvinyl alcohol as a principal component, the binder resin solution is applied to the separator and left until the fluidity thereof is lowered, and then the separator and the electrode are adhered to each other by bonding and drying. Thus, a battery having high adhesive strength and high ionic conductivity is provided.
