Abstract
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.
