Electrochemical energy storage devices
摘要
說明書
It will be appreciated that providing energy storage devices in electrical communication with photovoltaic cells may be useful, in embodiments, for modulating the output of the photovoltaic cell and minimizing variability in cell output. Additionally, when exposed to light, the excess electrical energy generated by the photovoltaic cell may be used to charge the energy storage device to store the excess energy. The stored energy may then be provided by the energy storage device as voltage output during non-peak times, such as during the night or on cloudy days, for example. Including the energy storage devices directly on the same structure as the photovoltaic cell is further advantageous for simplifying construction, integration, shipping, etc. Additionally, the use of the energy storage devices described herein may be beneficial, for example, as the energy storage devices may have large power densities and can receive and provide large current densities as needed, without damaging the energy storage devices or degrading their storage capacities. Further, the energy storage devices may exhibit large cycle lives without resulting in component degradation or capacity loss, making them beneficial for use in these photovoltaic applications as well as other energy storage applications.
The present invention may be further understood by reference to the following non-limiting examples.
