  • Patent number: 11328877
    Abstract: A poly(vinylphosphonic acid) (PVPA)?(NH4)2MoO4), gel polymer electrolyte can be prepared by incorporating redox-mediated Mo, or similar metal, into a PVPA, or similar polymer, matrix. Gel polymer electrolytes including PVPA/MoX, x representing the percent fraction Mo in PVPA, can be used to make supercapacitors including active carbon electrodes. The electrolytes can be in gel form, bendable and stretchable in a device. Devices including this gel electrolyte can have a specific capacitance (Cs) of 1276 F/g, i.e., a more than 50-fold increase relative to a PVPA system without Mo. A PVPA/Mo10 supercapacitor can have an energy density of 180.2 Wh/kg at power density of 500 W/kg, and devices with this hydrogel structure may maintain 85+% of their initial capacitance performance after 2300 charge-discharge cycles.

  • Patent number: 11279628
    Abstract: Previous hybrid-anion and cation-redox (HACR) cathodes were limited in cycling performance by irreversible anionic redox reactions caused by the loss of anions. To overcome this limitation, a lithium (Li) transition metal (M) oxide particle is described having a Li concentration gradient. In one example, the particle includes a Li-rich core region that provides capacity and energy density due anionic and cationic contributions and a Li-poor surface region surrounding the core region to inhibit anionic activity and thus substantially reduce the loss of anions. A gradient region disposed between the core and surface regions has a Li concentration profile that varies from a first Li concentration in the core region to a second Li concentration in the surface region. A high-temperature leaching method may be used to leach LiO from a Li-rich Li1+xM1?XO2 particle, thus forming a coherent Li gradient with a stabilized layered structure.

  • Patent number: 11177473
    Abstract: High-performance flexible batteries are promising energy storage devices for portable and wearable electronics. The major obstacle to develop flexible batteries is the shortage of flexible electrodes with excellent electrochemical performance. Another challenge is the limited progress in the flexible batteries beyond Li-ion because of safety concerns for the Li-based electrochemical system. Accordingly, a self-supported tin sulfide (SnS) porous film (PF) was fabricated as a flexible cathode material in Al-ion battery, which delivers a high specific capacity of 406 mAh/g. A capacity decay rate of 0.03% per cycle was achieved, indicating a good stability. The self-supported and flexible SnS film also shows an outstanding electrochemical performance and stability during dynamic and static bending tests. Microscopic images demonstrated that the porous structure of SnS is beneficial for minimizing the volume expansion during charge/discharge.
