摘要: Presented in the present disclosure are nanocomposites and batteries which are resistant to thermal runaway and may be used as cathode materials in batteries that tolerate operation at high temperatures. The nanocomposites include a nonconducting polymer and a carbon filler which includes a plurality of ultrathin sheets of a porous carbon material. The nonconducting polymer and carbon filler act in synergy to provide improved thermal stability, increased surface area, and enhanced electrochemical properties to the nanocomposite. For example, a battery that includes the nanocomposite as a cathode material was shown to have an enhanced performance and stability over a broad temperature range from room temperature to high temperatures (for example, of 100° C. or more). These batteries fill an important need by providing a safe and reliable power source for devices that are operated at high temperatures such as the downhole equipment used in the oil industry.

摘要: A nanocomposite including a metal oxide and two-dimensional nanosheets. The metal oxid includes at least one of zirconia and titania, and the two-dimensional nanosheets include at least one of reduced graphene oxide and boron nitride. A weight ratio of the metal oxide to the two-dimensional nanosheets is in a range of 2:1 to 19:1, or in a range or 2:1 to 9:1. Making the nanocomposite includes forming a first aqueous dispersion including zirconia nanoparticles and graphene oxide powder, combining a reducing agent with the first aqueous dispersion, irradiating the first aqueous dispersion with microwave radiation, thereby yielding a second aqueous dispersion including zirconia and graphene, and separating the nanocomposite from the second aqueous dispersion, wherein the nanocomposite comprises zirconia and graphene.

摘要: Presented in the present disclosure are nanocomposites and rechargeable batteries which are resistant to thermal runaway and are safe, reliable, and stable electrode materials for rechargeable batteries operated at high temperature and high pressure. The nanocomposites include a plurality of transition metal oxide nanoparticles, a plurality of ultrathin sheets of a first two-dimensional (2D) material, and a plurality of ultrathin sheets of a different 2D material, which act in synergy to provide an improved thermal stability, an increased surface area, and enhanced electrochemical properties to the nanocomposites. For example, rechargeable batteries that include the nanocomposites as an electrode material have an enhanced performance and stability over a broad temperature range from room temperature to high temperatures.
