Patent number: 9318269Abstract: The invention relates to a packaging structure of an energy storage device. At least one unit cell of capacitor is stacked and packaged into the energy storage device. The unit cell is a sandwich structure comprising a solid-state polymer electrolyte between two modified carbonaceous electrodes. An assembly of at least one unit cell of capacitor can be packaged by metallic cases to form a coin cell type or screw type of the packaging structure, packaged with a plastic case by compression molding or injection molding, or packaged by a plastic bag or an aluminum-foil bag and sealed by heat sealing or vacuum heat sealing. Manufacture processes for traditional capacitor modules, such as drilling, welding, screwing, and making scaffolds, are not required. Although the packaging process is simpler and less expensive, the packaged energy storage device can perform better than traditional capacitor modules.Type: GrantFiled: December 13, 2013Date of Patent: April 19, 2016Assignee: FENG CHIA UNIVERSITYInventors: Kuo-Feng Chiu, Shi-Kun Chen, Tse-Hao Ko

Patent number: 9208959Abstract: Disclosed is a super capacitor and method of manufacture thereof. This invention relates to a solid state super capacitor comprising a solid state polymer electrolyte and a modified carbonaceous electrode. Said modified carbonaceous electrode comprises a conductive carbonaceous material covered with active ingredients. Said modified carbonaceous electrode and said solid state polymer electrolyte are layered on top of each other to form a sandwich-like structure. Said super capacitor performs much better than known super capacitor comprising liquid or gel-form electrolytes. Said super capacitor has higher conductivity, therefore can be manufactured without a current collector. Since said super capacitor contains solid state polymer electrolyte, the method of manufacturing said super capacitor is more environmentally friendly and has a higher safety level.Type: GrantFiled: November 30, 2014Date of Patent: December 8, 2015Assignee: FENG CHIA UNIVERSITYInventors: Kuo-Feng Chiu, Shi-Kun Chen, Tse-Hao Ko
