HIGH ENERGY NI-ZN BATTERY DEVELOPMENT

一种新型经皮高能电池系统的研究 能量传输，例如在脑室辅助系统(VAS)或其他 提出了心脏泵的概念。发展是建立在稳定基础上的 由伊奇米卡公司开发的镍锌电池系统，该公司提供 以下优势： A)能量密度是目前镍镉电池的两倍 B)循环寿命长 C)较高的电池电压导致给定电池的电池数量较少 电压 到目前为止，镍锌只有通风槽的形式可用。 密封电池是VAS内部电源的必需品， 对于外部单元，它们也是可取的。作为实现以下目标的关键方法 提出了一种氧复合技术用于镍锌电池的密封 这将允许在充电和过度充电方面有相当大的自由度 而不会在电池中产生任何显著的压力。四项任务 提出了六个月(第一阶段)计划，以发展这项技术和 建立面向未来硬件的CEL设计的基本方法 在第二阶段晚些时候为设备应用开发。

Investigation of a new high energy battery system for transcutaneous transmission of energy e.g. in a Ventricular Assist System (VAS) or other heart pumps is proposed. The development is based on the stabilized nickel-zinc battery system developed by Electrochimica Corp. which offers the following advantages: a) an energy density twice that of present nickel-cadmium cells b) a long cycle life c) A higher cell voltage resulting in fewer cells for a battery of a given voltage Up to now the nickel-zinc has been available only in vented cell forms. Sealed batteries are a necessity for the internal power source of a VAS and they are also desirable for the external units. As a key approach towards sealing of nickel-zinc cells an oxygen recombination technique is proposed which would permit considerable latitude in charging and overcharging without developing any significant pressures in the battery. A four task six mo (Phase I) program is presented, to develop this technique and establish a basic approach towards cel design for future hardware development later in Phase II for device applications.
