US Patent:

20230021439, Jan 26, 2023

Filed:

Sep 29, 2022

Appl. No.:

17/936781

Inventors:

- Wilsonville OR, US
Kenneth Kiyoshi Fisher - Portland OR, US
Timothy McDonald - Portland OR, US

International Classification:

H01M 8/18
H01M 8/04276
H01M 8/04119
H01M 4/86
H01M 8/04225
H01M 50/60

Abstract:

Methods and systems are provided for transporting and hydrating a redox flow battery system with a portable field hydration system. In one example, the redox flow battery system may be hydrated with the portable field hydration system in a dry state, in the absence of liquids. In this way, a redox flow battery system may be assembled and transported from a battery manufacturing facility to an end-use location off-site while the redox flow battery system is in the dry state, thereby reducing shipping costs, design complexities, as well as logistical and environmental concerns.

International Classification:

H01M 8/04276
H01M 8/04119
H01M 8/18
H01M 8/04298

Abstract:

Methods and systems are provided for a redox flow battery system. In one example, a method of operating a redox flow battery system includes switching the redox flow battery system to an idle mode and completely draining electrolytes from one or more electrode compartments of the redox flow battery system. The one or more electrode compartments may be purged with a gas and refilled with fresh electrolytes.

International Classification:

H01M 8/04276
H01M 8/04186
H01M 8/18

Abstract:

A rebalancing reactor for a redox flow battery system may include a plurality of reactor vessels arranged in stages, each vessel of the plurality of reactor vessels housing a catalyst bed. In one example, the rebalancing reactor is fluidly coupled to an electrolyte storage tank and configured to flow electrolyte through the plurality of reactor vessels, enabling a chemical rebalancing of electrolyte in the redox flow battery cell.

Abstract:

A multi-chambered electrolyte storage tank for a redox flow battery system, may include first and second electrolyte chambers, and a bulkhead, wherein the first and second electrolyte chambers are fluidly coupled to first and second sides of a redox flow battery cell, respectively, the first and second electrolyte chambers include first and second liquid electrolyte volumes, respectively, and the first and second liquid electrolyte volumes are separated by the bulkhead positioned therebetween. In this way, manufacturing and operational complexity of a redox flow battery system can be reduced.
