Latest Patents

One of Liu's latest patents focuses on a hybrid cell design that incorporates alternately stacked or wound lithium-ion battery and capacitor electrodes. This innovative design features electrodes formed with a porous layer of particulate electrode material bonded to each of the two major sides of a compatible metal current collector. In one embodiment, opposing electrodes are created using similar lithium-ion battery anode materials or like cathode materials or capacitor materials on both sides of the current collector. Another embodiment involves applying a battery electrode material to one side of a current collector while using capacitor material on the opposite side. The electrodes are generally formed by combining a suitable grouping of capacitor layers with unequal numbers of anode and cathode battery layers. By assembling one or more pairs of opposing electrodes, Liu's design provides a combination of battery and capacitor energy and power properties in a hybrid electrochemical cell. The cells can be constructed by stacking or winding rolls of the opposing electrodes with interposed separators.
