Abstract

The present disclosure provides an energy storage molecular material, crystal dielectric layer and capacitor which may solve a problem of the further increase of volumetric and mass density of reserved energy associated with some energy storage devices, and at the same time reduce cost of materials.

Claims

1. An energy storage molecular material having a general molecular structural formula:

2. An energy storage molecular material according to claim 1, wherein the doped oligoaniline is self-doped oligoaniline with SO₃-groups or COO-groups on the phenyl rings of aniline.

3. An energy storage molecular material according to claim 1, wherein the doped oligoaniline is mix-doped by acid compounds selected from the group of alkyl-SO₃H acid or alkyl-COOH mixed to oligoaniline in oxidized state.

4. An energy storage molecular material according to claim 1, further comprising at least one linker unit selected from the group of the following structures:

33-42, which connect the predominantly planar polycyclic molecular system (Cor) with the polarization units (P);

5. A crystal dielectric layer comprising the energy storage molecular material according to any of claims 1, 2, 3, 4.

6. A capacitor comprising

a first electrode,

a second electrode, and

a crystal dielectric layer disposed between said first and second electrodes,

wherein said crystal dielectric layer comprises the energy storage molecular material according to any of claims 1, 2, 3, 4.
