摘要

Hot Plate with cell between constrained plates: 1. Thermal Runaway occurred at 170C. Overcharge with cell between constrained plates: 1. 5.3Vdc at 1C charge rate venting occurred: (1) Added 30 AH additional capacity to 10 AH cell; 2. 5.3Vdc at 2C charge rate cell went into thermal. runaway (added 30AH additional capacity to 10AH Cell). Pinch Test ～1500lbs of force on broad face of cell: 1. No change in open circuit V and/or temperature. 2. Slight difference in capacity after 107 charge and discharge cycles. Broad Face Indent (Metal and Ceramic Tips): 1. Internal short circuit induced at 57.6 lbf; 2. Induced a thermal runaway condition. Narrow Face Indent (Ceramic Tip): 1. Internal short circuit induced at 37 Ibf; 2. Induced a thermal runaway condition.
