Flexible graphite as a heating element

2002/1/1Flexible graphite is an effective heating element. It provides temperatures up to 980 C (though burn-off occurs in air at 980 C), response half-time down to 4 s, and heat output at 60 s up to 5600 J.The electrical energy for heating by 1 C is 1–2 J in the initial portion of rapid temperature rise.

Zirconia

Zirconia has been incorporated into exfoliated graphite (EG) through the anodic polarization in the natural graphite-ZrO(NO3)2-HNO3-H2O system, followed by flash heating. The thermal properties of the oxidized graphites employed as precursors to EG have been studied by thermogravimetry in combination with differential scanning calorimetry, and the distribution of ZrO2 particles in the EG has

Watts density explained

2013/7/24Watts density is the amount of heating energy emanating from any given amount of surface area of the hot part of an element. In Imperial Britain and the States, this is usually described in terms of watts per square inch, but could be expressed (to keep the Eurocrats happy) as watts per square cm, mm, or indeed, meter.

Flexible and Stackable Laser

In this paper, we demonstrate that by simple laser induction, commercial polyimide films can be readily transformed into porous graphene for the fabrication of flexible, solid-state supercapacitors. Two different solid-state electrolyte supercapacitors are described, namely vertically stacked graphene supercapacitors and in-plane graphene microsupercapacitors, each with enhanced

Carbon DotsrGO Paper as Freestanding and Flexible

However, carbonaceous materials with graphite‐layers structure usually suffer from poor cycle life and inferior stability, not to mention freestanding and flexible PIBs. Here, a freestanding and flexible 3D hybrid architecture by introducing carbon dots on the reduced graphene oxide surface (CDsrGO) is synthesized as high performance PIBs anode.
