摘要：How to screen defective lithium ion batteries is of great importance to the producers and consumers, which has been a challenging problem, since some lithium ion batteries will not present evident different electrochemical behaviors at the initial use stage. Here, we found that defective lithium ion batteries of zero open-voltage could be differentiated from the good ones by charging at 1,800 mA (corresponding to 3 C) in combination with in situ infrared thermal imaging technology. During the charge process, the surface temperatures of the defective lithium ion batteries of zero open-voltage showed at least 10 degrees C higher than that of the good one. Results of the charge voltage, charge current, temperature rise, and the analysis of the cathode strip, separator, and anode strip after full-discharge process showed that this method was effective.
