摘要： A power source including two alkali metal/transition metal oxide cells discharged in parallel to power an implantable medical device is described. The first cell powers the medical device in both a device monitoring mode, for example in a cardiac defibrillator for monitoring the heart beat, and a device actuation mode for charging capacitors requiring high rate electrical pulse discharging. At such time as the first cell is discharged to a predetermined voltage limit, the first cell is disconnected from pulse discharge duty and only used for the device monitoring function. At that time, the second cell is utilized for the high rate electrical pulse discharging function. When the first cell reaches 100% efficiency or a present voltage limit, the second cell then takes over both device monitoring and device actuation functions. In that manner, a greater average discharge efficiency is realized from the two cells than is capable of being delivered from a single cell of similar chemistry.
摘要翻译：描述了包括并联排放的两个碱金属/过渡金属氧化物电池以为可植入医疗装置供电的电源。第一单元在设备监视模式中为医疗设备供电，例如用于监测心跳的心脏除颤器，以及用于对需要高速率电脉冲放电的电容器进行充电的设备致动模式。在第一电池放电到预定电压极限时，第一电池与脉冲放电占空比断开，仅用于器件监视功能。此时，第二个电池用于高速电脉冲放电功能。当第一个电池达到100％效率或当前的电压限制时，第二个电池接管器件监测和器件致动功能。以这种方式，从两个电池实现的平均放电效率比能够从类似化学的单个电池输送的平均放电效率更高。

摘要： A lithium electrochemical cell including an anode and cathode assembly with the anode connected electrically to a conductive cell casing and an insulated cathode conductor extending through a lid at an end of the casing and connected to a cathode lead near the lid and with a first insulating component for insulating the casing from cell components therein and extending along and within the casing from a closed end thereof toward the lid, and which is characterized by a second insulating component for insulating the lid from components in the casing and extending along within the lid and toward the first insulating bag so as to prevent a short circuit between the lid or casing and the cathode assembly caused by formation of lithium clusters in the region between the lid or casing and the cathode connector. Preferably the second insulating component is in the form of a cup having a relatively thin base portion extending along the lid and a relatively thin wall portion extending from the base along within the casing and toward the first insulating component which also is in the form of a thin-walled cup. The walls of the first and second insulating components preferably meet in overlapping relation. The insulating arrangement is particularly adapted for use in a cell wherein the anode and cathode assembly comprises a plurality of cathode plates with anode sections interposed therebetween.

摘要： A combination separator comprising a single layer of a non-woven, polyolefinic cloth superposed with a single layer of a polyolefinic, microporous film for use in an electrochemical cell, is described. A preferred polyolefinic material for both the non-woven cloth and the microporous film is polypropylene. The redundancy of using two layers of separator is an enhanced safety characteristic of the cell; however, the use of the polypropylene web/film combination adds another dimension to the cell's safety characteristics by imparting the benefits of each type of material.
