摘要： The present invention relates to a current collector including a base portion with a flat face, primary projections projecting from the flat face, and secondary projections projecting from the top of the primary projections. The present invention also relates to a current collector including a base portion with a flat face and primary projections projecting from the flat face, wherein the roughening rate of the top of the primary projections is 3 to 20. By using such a current collector, separation of the active material from the current collector can be inhibited when using an active material that has a high capacity but undergoes a large expansion at the time of lithium ion absorption.

摘要： The present invention relates to a rechargeable lithium ion battery having an electrode plate with a high active material density and high electrolyte permeability. Upon producing the rechargeable lithium ion battery, hollow resin particles that can be collapsed by rolling are incorporated in a positive electrode mixture layer or a negative electrode mixture layer before the electrode mixture layer is rolled. The hollow resin particles are collapsed in the course of rolling the positive electrode mixture layer or the negative electrode mixture layer, so that the active material density can be easily increased. Further, the collapsed resin particles form unevenness on the surface of the electrode plate and also form open pores in the electrode plate, so that electrolyte permeability can be enhanced. As a result, the discharge capacity and rate characteristics of rechargeable lithium ion batteries can be increased.
