Abstract: A method of fabricating a capacitor can include prelithiating a carbon material to form a first layer for the capacitor. The first layer including an anode or being an anode layer. A second layer can be positioned between the first layer and a third layer. The second layer can be or include a membrane and the third layer can be or include a cathode. The third layer can include activated carbon or utilize activated carbon as a cathode. Capacitors can be formed by use of this method and devices can utilize such capacitors. Instead of relying on lithium in metallic form, a carbon material can be prelithiated to include lithium ions therein to form an anode for the LIC that avoids use of lithium foil or lithium powder in the LIC and also avoid use of lithium in a metallic form in the LIC.

Abstract: The embodiments herein provide for an oxygen/air cathode that includes metal-organic frameworks and/or hybrids of metal-organic frameworks and carbon networks. The metal-organic-framework-based Li—O2 cells are operated in humid O2 where water plays a critical role in improving battery performance. Such embodiments not only improve battery performance but also reduces the cost by cycling the Li—O2 batteries in humid oxygen with MOF@CNT hybrid catalysts.

Abstract: An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode, where the anode and/or electrode includes an electrode film having a super-fibrillized binder material and carbon. The electrode film can have a reduced quantity of the binder material while maintaining desired mechanical and/or electrical properties. A process for fabricating the electrode film may include a fibrillization process using reduced speed and/or increased process pressure such that fibrillization of the binder material can be increased. The electrode film may include an electrical conductivity promoting additive to facilitate decreased equivalent series resistance performance. Increasing fibrillization of the binder material may facilitate formation of thinner electrode films, such as dry electrode films.
