DESCRIPTION (provided by applicant): Rechargeable lithium-ion batteries (LIB) are providing power for an increasing range of portable medical devices. With their light weight and higher voltages, device capabilities have improved within acceptable weight limits for portability. However, the batteries' issues with reliability, safety, service life and operating temperature range, have limited their acceptance. Automated External Defibrillators (AEDs) in particular are used in a wide variety of use cycles in the field and in hospitals, airports, households and workplaces. The units with the LIBs can see long storage periods in different states of charge and at wide temperature extremes. Giner, Inc. has developed new battery electrolytes with exceptional chemical stability, non- flammability and wide temperature range, which will be evaluated with a new 5-V cathode material to safely increase specific power and specific energy of lithium-ion batteries for use in lighter and more compact units. The new battery chemistry has the potential to increase cell operating voltages from 3.6 V to 4.5 V. Giner, Inc. will team with a commercial producer of AEDs, Zoll Medical Corp., to develop and demonstrate the next generation of lithium ion batteries to facilitate increased reliability and expanded capabilities o these emergency care devices in a wider range of environments and use cycles. Testing will be conducted to show the increased operating life-time and charge retention compared with commercial cells. Experimental cells will be built with the new materials and cycled with a wide range of charge and discharge rates and at temperatures over the range of 0oC to 50oC. The new cells will also be tested in voltage ranges corresponding to overcharge and overdischarge to demonstrate improvements in user safety and abuse tolerance. Testing will be conducted at Giner's battery engineering development laboratory which permits simultaneous battery cycle testing of up to 24 cells. All results will be compared with performance of commercial lithium-ion cells which represent the state-of-the-art. Based on these results and input from Zoll, a battery pack design will be developed as a prototype for new AEDs which are currently under development. The design and the performance parameters determined in Phase I will be used in Phase II to fabricate full battery prototypes that will be tested and integrated with new portabe AED designs. The prototypes will have the necessary I/O communication and microprocessors to ensure safe and reliable integration with new devices. PUBLIC HEALTH RELEVANCE: The proposed material improvements will enhance the performance, safety, reliability and operating life of rechargeable lithium-ion batteries used in portable medical devices, such as automated external defibrillators (AEDs). Higher cell voltage will permit the design of smaller battery packs with fewer cells in series to achieve the necessary device voltage and power. The improved batteries will have better capacity retention on storage to increase total service life and reliability for emergency medical AED services operating in the field.

描述（由申请人提供）：可充电锂离子电池（LIB）正在为越来越多的便携式医疗器械提供电源。由于重量轻、电压高，器件的性能在可接受的重量范围内得到了提高，便于携带。然而，电池在可靠性、安全性、使用寿命和工作温度范围方面的问题限制了它们的接受度。自动体外除颤器（AED）特别用于现场和医院、机场、家庭和工作场所的各种使用周期。具有LIB的单元可以在不同的充电状态和宽的温度极限下看到长的存储时间。Giner公司公司已开发出具有卓越化学稳定性、不易燃性和宽温度范围的新型电池电解质，将使用新型5 V阴极材料对其进行评估，以安全地提高锂离子电池的比功率和比能量，用于更轻、更紧凑的装置。新的电池化学物质有可能将电池工作电压从3.6 V提高到4.5 V。将与 AED的商业生产商Zoll Medical Corp.，开发和展示下一代锂离子电池，以提高这些紧急护理设备在更广泛的环境和使用周期中的可靠性和扩展能力。将进行测试以显示与商业电池相比增加的操作寿命和电荷保持。实验电池将使用新材料制造，并在0 ℃至50 ℃的温度范围内以广泛的充电和放电速率进行循环。新电池还将在对应于过充电和过放电的电压范围内进行测试，以证明用户安全性和滥用容忍度的改善。测试将在Giner的电池工程开发实验室进行，该实验室允许同时对多达24个电池进行电池循环测试。所有结果将与代表最新技术水平的商用锂离子电池的性能进行比较。基于这些结果和Zoll的输入，将开发电池组设计，作为目前正在开发的新型AED的原型。在第一阶段确定的设计和性能参数将用于第二阶段，以制造完整的电池原型，这些原型将被测试并与新的便携式AED设计集成。原型将具有必要的I/O通信和微处理器，以确保与新设备的安全可靠集成。 公共卫生相关性：拟议的材料改进将提高便携式医疗设备（如自动体外除颤器（AED））中使用的可充电锂离子电池的性能、安全性、可靠性和使用寿命。更高的电池电压将允许设计具有更少串联电池的更小的电池组，以实现必要的设备电压和功率。改进后的电池将具有更好的存储容量，以增加在现场操作的紧急医疗AED服务的总使用寿命和可靠性。
