  • Patent number: 10727471
    Abstract: A method for manufacturing a lithium ion polymer battery is provided in which in injecting electrolyte into a lithium ion polymer battery, the battery cell is immersed in an electrolyte impregnation bath to allow the electrolyte to be impregnated into the cell. The electrolyte can be impregnated simultaneously, and as the battery cell is activated, the electrolyte is settled down in the interior of the battery cell. Thus, when the battery cell is sealed, a phenomenon that the electrolyte is present at the sealed portion can be prevented.

  • Patent number: 10727187
    Abstract: A solid oxide battery includes a solid electrolyte disposed between a first electrode and a second electrode. The first electrode and the second electrode are coupled to an external source or load to charge or discharge the solid oxide battery. The solid electrolyte is formed from a proton conducting material to transport and store hydrogen, which is the source of chemical energy. The second electrode is formed from a noble metal configured to induce formation of oxygen vacancies at the interface between the second electrode and the solid electrolyte. The oxygen vacancies are used to split water molecules during charging of the solid oxide battery, which results in the generation of hydrogen. Under bias, the hydrogen ions are transported into the solid electrolyte and stored. During discharge, a reverse process occurs where hydrogen is used to generate water and electricity.

  • Patent number: 10680300
    Abstract: Carbon nanosheets fabricated by carbonization and activation or by carbonization alone. The nanosheets possess a disordered structure for copious reversible binding of ions at the carbon defects. They are also hierarchically micro-meso-macro porous, allowing facile ion transport at high rates both through the pore-filling electrolyte and in the solid-state. Also, a combined battery—supercapacitor energy storage device using the carbon nanosheets as one or both of the electrodes therein. Tuning the mass-loading ratio of the carbon nanosheets in the two electrodes configures the carbon nanosheets to operate either as a bulk insertion electrode (anode) or a surface adsorption electrode (cathode). The energy storage device may further include a housing with a form factor of a commercial battery.

  • Patent number: 10665852
    Abstract: A method for reducing residual water content in a battery material includes placing the battery material having residual water adsorbed therein in a channel substantially sealed from an ambient environment. A gaseous mixture is caused to flow through the battery material in the channel. The gaseous mixture includes an organic solvent vapor present in an amount effective to hydrogen bond with at least some water molecules from the battery material. The gaseous mixture is caused to flow through the battery material for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure. The organic solvent vapor having at least some water molecules bonded thereto is removed from the battery material. The removing takes place for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure, thereby forming the battery material having reduced residual water content.
