摘　　要：制备了一正一负型平板聚合物锂离子电池,评价了电池在受力条件下的性能。实验结果表明:在压应力σ1<3MPa或拉应力σ2<1.5MPa时,挤压和拉伸对性能有一定的影响;弯曲对性能有严重的损害;在单位长度扭转角φ>18(°)/cm时,扭转对性能有严重的损害。Flat polymer Li-ion battery with one cathode and one anode was made. The performance of the battery under mechanical deflections was evaluated. The experiment results indicated that when the compressive stress σ1 〈 3 MPa or the tensile stress σ2 〈 1.5 MPa, pressing and stretching had some effects on the performance; bending caused great damage to the performance; torsion caused great damage to the performance when the torsion angle within unit length φ 〉 18 （°）/cm.
