摘要：

Nickel/zinc batteries are currently being manufactured under contract to the National Institutes of Health (NIH) for a left ventricular assist device (LVAD). The nickel/zinc system is being developed to replace the current lead-acid battery in this application. First generation prototype cells provide 60 Wh kg(-1), which is a weight saving of more than 35% compared to the lead-acid battery in current use. Further optimization of this design will result in a projected energy density of 70 Wh kg(-1) by reducing the cell weight by 15%. Cell characterization and accelerated testing are underway to establish cell performance as a function of cycle life.
