Summary
Lithium-air batteries need protection from humid air to prevent lithium corrosion. Oxygen selective membranes (OSMs) allow oxygen entry while blocking water, enabling long-life applications.
Area of Science:
- Electrochemistry
- Materials Science
- Energy Storage
Background:
- Lithium-air (Li-air) batteries offer superior theoretical energy density compared to conventional lithium batteries.
- Protecting the lithium metal anode from water vapor corrosion in ambient, humid conditions is critical for Li-air battery longevity.
- Current Li-air battery technology faces challenges with electrode degradation during discharge.
Purpose of the Study:
- To review and discuss the essential properties of oxygen selective membranes (OSMs) for Li-air battery applications.
- To explore potential materials suitable for use as OSMs in Li-air battery systems.
- To address the challenge of preventing lithium metal corrosion in Li-air batteries operating under humid conditions.
Main Methods:
- Literature review of existing research on oxygen selective membranes for Li-air batteries.
- Analysis of membrane properties required to selectively allow oxygen ingress while inhibiting water vapor.
- Discussion of various candidate materials and their performance characteristics for OSMs.
Main Results:
- OSMs are identified as a key component for protecting the lithium anode from water vapor.
- Specific material properties, such as high oxygen permeability and low water vapor transmission, are crucial for effective OSMs.
- Several classes of materials show promise for OSM development in Li-air batteries.
Conclusions:
- Oxygen selective membranes are a viable strategy to mitigate lithium anode corrosion in Li-air batteries.
- Further research into developing and optimizing OSM materials is necessary for practical Li-air battery implementation.
- The successful deployment of OSMs will enhance the durability and lifespan of lithium-air batteries for long-life applications.

2.2K
Membrane electrodes, also known as p-ion electrodes, use membranes that selectively interact with free analyte ions, generating a potential difference across the membrane. The resulting membrane potential, known as the asymmetry potential, is not zero even when analyte concentrations on both sides of the membrane are equal. The membrane's response is typically not selective to a single analyte but proportional to the concentration of all ions in the sample solution capable of interacting at...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Oxygenic photosynthesis is a fundamental process in which light energy is harnessed to drive the oxidation of water, leading to the production of molecular oxygen (O₂), adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH). This process is essential for sustaining aerobic life on Earth and is primarily carried out by cyanobacteria, algae, and plants. The core of oxygenic photosynthesis lies in the thylakoid membranes, where chlorophyll pigments facilitate...
