6 FAQs about [Ion membrane energy storage]
What are ion-conductive membranes used for?
Membranes with fast and selective ion transport are widely used for water purification and devices for energy conversion and storage including fuel cells, redox flow batteries and electrochemical reactors. However, it remains challenging to design cost-effective, easily processed ion-conductive membranes with well-defined pore architectures.
How many ion exchange membranes are needed to achieve net zero emissions?
To achieve net zero emission targets by 2050, future TW-scale energy conversion and storage will require millions of meter squares of ion exchange membranes for a variety of electrochemical devices such as flow batteries, electrolyzers, and fuel cells.
Why are ion exchange membranes important?
Firstly, the increased cost of ion exchange membranes accounts for the largest proportion, so it is of great significance to develop ion exchange membranes with lower cost and longer life. Secondly, the additional pump power used to drive the intermediate electrolyte is very small, so the increased energy cost can be neglected.
Can low-cost hydrocarbon membranes be used in a large-scale electrochemical energy storage application?
This work will inspire the development of next-generation cost-effective flow batteries based on low-cost hydrocarbon membranes for large-scale electrochemical energy storage applications.
Where can iontronic energy be stored?
The iontronic energy based on osmotic effects could be stored on the edge of a PET substrate and Kapton film. The vertical structure effectively decreased the internal resistance of the device and showed a superior practical performance due to its enhanced power output with a relatively large film area and a shorter ion-transport distance.
How to make iontronic energy storage device?
The Ag paste was printed onto the PET film via screen-printing apparatus to form the Ag electrodes, and these were cured in air drying oven at 130 °C for 30 min. An ultrasonic spray-coating system (Cheersonic UAM7000-BN, with a UCA123 spray nozzle) was used to fabricate the iontronic energy storage device (Supplementary Fig. 35).
