  • Patent number: 10957911
    Abstract: The present invention relates to a negative electrode including a multi-protective layer and a lithium secondary battery including the same. The multi-protective layer is capable of effectively transferring lithium ions to a lithium metal electrode while physically suppressing lithium dendrite growth on the electrode surface, and does not cause an overvoltage during charge and discharge since the protective layer itself does not function as a resistive layer due to excellent ion conductivity of the multi-protective layer, and therefore, is capable of preventing battery performance decline and securing stability during battery operation.

  • Patent number: 10103547
    Abstract: A solar cell management system for increasing the efficiency and power output of a solar cell and methods for making and using the same. The management system provides an electric field across one or more solar cells. The imposed electric field exerts a force on both the electrons and holes created by light incident on the solar cell and accelerates the electron-hole pairs towards the electrodes of the solar cell. The solar cell management system considers variations in configuration of solar cells to maximize the power output of the solar cells. The accelerated electron-hole pairs have a lower likelihood of recombining within the cells' semiconductor's material. This reduction in the electron-hole recombination rate results in an overall increase in the solar cells' efficiency and greater power output.
