摘要
提出了运用直流测内阻诊断聚合物锂离子电池内部短路的方法，简述了该方法的基本原理，给出了用于电池内部短路判断的经验值范围。所述方法既可单独运用进行电芯化成前的分选，又可以综合应用进行电池质量的综合判断和电芯的出库分选。
： DC method used to measure the internal resistance of polymer Li-ion battery for the determination of the inner short of the battery was proposed.The theory of this method was also described,and the range of the empirical value which is used to determine the inner short of a battery was also indicated.The method not only can be used for the classification of the polymer Li-ion cells before formation，but also can be used for the synthetical estimation of the quality of the cells and the classification before they are to be assembled.
