摘要： Presented here are nanocomposites and rechargeable batteries. In certain embodiments, nanocomposites a nanocomposite is resistant to thermal runaway, and useful as an electrode material in rechargeable batteries that are safe, reliable, and stable when operated at high temperature and high pressure. The present disclosure also provides methods of preparing rechargeable batteries. For example, rechargeable batteries that include nanocomposites of the present disclosure as an electrode material have, in some embodiments, an enhanced performance and stability over a broad temperature range from room temperature to high temperatures. These batteries fill an important need by providing a safe and reliable power source for devices operated at high temperatures and pressures such as downhole equipment used in the oil industry.

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. These batteries fill an important need by providing a safe and reliable power source for devices operated at high temperatures and pressures such as downhole equipment used in the oil industry.

摘要： An electrode that includes a nanocomposite and sulfur is provided. The nanocomposite includes from 0.1 to 15 wt. % of a metal oxide, carbon, and h-BN. Also provided is a lithium-sulfur battery that has an anode, a cathode, a separator and an electrolyte. The cathode of the lithium-sulfur battery includes the nanocomposite and sulfur. A method of preparing an electrode is also provided. The method includes milling a metal precursor, carbon, and h-BN to make a precursor mixture and heating the precursor mixture to a predetermined temperature in the presence of oxygen to form the nanocomposite. The method then includes mixing the nanocomposite with sulfur to create an electrode mixture, and forming an electrode from the electrode mixture.
