New lithium-thionyl chloride spiral wound D-size cell for mediumand high current applications

摘要

In response to an ever-increasing need for cells with greatercapacity at higher current, the LSH20 HD, a D-size high rateLiSOCl₂ cell designed to perform in the 0.1-5.0 A range witha 30 to 50% increase versus the existing LSH20 standard cell, wasdeveloped. The design is described. The capacity vs. current in the0.1-5.0 A range varies slightly with the discharge conditions. Dependingon current, there is a 30 to 60% improvement vs. the standard LSH20 celland 15 to 70% vs. existing LiSO₂ products. The position ofthe cell during discharge does not influence performance. The LSH20 HDD-size cell combines attractive energy capacity with operating voltagesabove 3 V in a wide temperature range
