US Classification:

136256, 546 37, 544 99, 544 31, 544347, 136263

Abstract:

The present invention provides a organic compound of the general structural formula 1 and photovoltaic device and photovoltaic layer comprising thereofSaid organic compound forms rod-like supramolecules and absorbs electromagnetic radiation in at least one predetermined spectral subrange within a wavelength range from 400 to 3000 nm with excitation of electron-hole pairs. The polycyclic core Cor, the bridging group B, and the polycyclic core Corform a molecular system selected from the list comprising donor-bridge-acceptor-bridge-donor and acceptor-bridge-donor-bridge-acceptor in which a dissociation of excited electron-hole pairs is carried out. A solution of the organic compound or its salt forms a solid photovoltaic layer on a substrate.

Abstract:

Provided are printed electrochemical cells, which utilize zinc salts for ionic transfer, and methods of fabricating such cells. In some examples, a printed electrochemical cell comprises a positive electrode with a positive current collector having a two-dimensional shape and comprising an electrolyte-facing surface formed by the graphite. For example, the positive current collector may be a graphite foil or an aluminum foil with a graphite coating. The cell also comprises electrolyte comprising an electrolyte salt and an electrolyte solvent. For example, the electrolyte salt comprises a zinc salt with a concentration of at least 30% by weight in the electrolyte. The cell is fabricated by printing a positive active material layer over the positive current collector, printing one or more electrolyte layers on various cell components, and laminating a separator layer between the positive and negative electrodes while soaking the separator layer with the electrolyte.

H01M 4/30
H01M 10/30
H01M 4/04

Abstract:

A rechargeable battery cell includes an electrode and an ion exchange material arranged to define an interpenetrating interface with at least a portion of the electrode. Providing an interpenetration interface in intimate contact can include completely or partially embedding the electrode in the ion exchange material, or alternatively, surrounding the electrode or discrete portions of the electrode with a thin film of ion exchange material. In one embodiment, electrodes can be particles fully or partially embedded, coated with, or partially contacting ion exchange material.
