Flow-batteriet er på vej frem | Ingeniøren

Derfor er bl.a flowbatterier på vej til at kunne konkurrere med fx lithium-ion på faste installationer. Derved frigøres lithium-ion fra grid-batteri til mere vægt-kritiske formål, fx køretøjer og fartøjer. En kortrækkende el-færge kan glimrende drives fra lithium-ion, og have et flowbatteri på kajen til at midle grid-strømmen.

Lithium-ion flow battery

Lithium-ion flow battery. A lithium-ion flow battery is a flow battery that uses a form of lightweight lithium as its charge carrier. [1] The flow battery stores energy separately from its system for discharging. The amount of energy it can store is determined by tank size; its power density is determined by the size of the reaction chamber.

An Innovative Concept of Membrane-Free Redox Flow Batteries …

Given that the ion-exchange membrane takes up more than 30% of redox flow battery (RFB) cost, considerable cost reduction is anticipated with the membrane-free design. However, eliminating the membrane/separator would expose the membrane-free RFBs to a higher risk of short-circuits, and the dendrite growth may aggravate this issue.
