A hybrid lithium-ion battery-capacitor (H-LIBC) energy storage device includes a hybrid composite cathode electrode having a lithium ion battery (LIB) cathode active material and a lithium ion capacitor (LIC) cathode active material. An anode electrode having a surface is pre-loaded and pressed with a lithium (Li) thin film source. The anode electrode is pre-lithiated with the lithium film source by positioning the Li film source on the surface of anode electrode after electrolyte filling and soaking processes, a separator and an organic solvent electrolytic solution including a lithium salt electrolyte are also provided. A method of making a hybrid lithium-ion battery-capacitor and a method of making a hybrid composite cathode for a hybrid lithium-ion battery-capacitor are also disclosed.

An apparatus for the in situ NMR monitoring of a battery including an anode, a separator and an air cathode is provided. The apparatus includes a non-metallic anode container portion, a non-metallic cathode container portion, and non-metallic connecting structure and sealing structure for connecting and sealing the anode container portion and the cathode container portion to define a hermetically sealed interior space for containing the battery with an anode of the battery adjacent the anode container portion and an air cathode of the battery adjacent the cathode container portion. The cathode container portion includes an air chamber portion with an air inlet and an air outlet. The air chamber portion can be adjacent to the air cathode such that air flowing from the air inlet to the air outlet will contact the air cathode. A method of evaluating an air cathode battery and a battery assembly for the NMR spectroscopy of an air cathode battery are also disclosed.

A metal air flow battery includes an electrochemical reaction unit and an oxygen exchange unit. The electrochemical reaction unit includes an anode electrode, a cathode electrode, and an ionic conductive membrane between the anode and the cathode, an anode electrolyte, and a cathode electrolyte. The oxygen exchange unit contacts the cathode electrolyte with oxygen separate from the electrochemical reaction unit. At least one pump is provided for pumping cathode electrolyte between the electrochemical reaction unit and the oxygen exchange unit. A method for producing an electrical current is also disclosed.
