The bipolar battery design minimizes IR losses between adjacent cells in a cell-stack and provides for uniform current and potential distributions over the active surface area of each cell component. The rechargeable lithium-ion electrochemistry is capable of high pulse power for cell components arranged in bipolar configuration. This system has delivered more than 3000 charge discharge cycles of pulse power and five-second pulses at current densities as high as 70 mA cm −2. The present programme is concerned with bipolar cell design, component fabrication and evaluation, multi-cell stack assembly and evaluation for development of a 270 V 2 Ah bipolar lithium-ion battery for aerospace and aircraft applications.
