摘要：

An organosulfur compound cathode material was prepared by hot-pressing a mixture of polyacrylonitrile nanofiber nonwoven and sulfur on carbon paper substrate at 300 degrees C. The organosulfur compound showed good heat resistance above 500 degrees C. The organosulfur cathode showed high capacity of over 600 mAh g(-1), long cycle life more than 1,000 cycles, and wide temperature range of -30 degrees C to 60 degrees C. Energy density per weigh of the organosulfur cathode was twice the conventional positive materials.
