Secondary Battery Science: At the Confluence of Electrochemistry and Materials Engineering.

摘要: Considerations of energy density, power, and calendar life are critical to effectively develop advanced secondary systems. For next generation battery applications requiring multiple features including long life, large cycle count, high density new strategies needed for the rational design electroactive materials electrodes. This article discusses several conceptual approaches under exploration with examples from our research group. The first approach is systematic synthesis structures facilitating ion insertion deinsertion at voltage where we control properties such as surface area, particle size in particular crystallite size. A second investigation novel electrode substrates increase capacity retention cycling, have developed minimizing passive components. third catalysts metal air batteries cathode active material drawn rather than carried battery.
