Water’s dual nature as a cheap, yet chemically unstable, substance with diverse applications.
The Properties of Water
Water is a unique substance with several distinct properties that make it an essential component of our daily lives. One of its most notable characteristics is its affordability. Water is one of the most inexpensive substances on the planet, making it accessible to people from all walks of life. This affordability is due to its abundance and the fact that it is not a rare or valuable resource.
Chemical Stability and Voltage Limitations
However, water has a significant drawback: its chemical stability is limited. It can conduct ions, which makes it an excellent conductor of electricity. But, this property also has a major limitation. Water is chemically stable only up to a voltage of 1.23 volts. This means that if the voltage exceeds this threshold, water can break down and become unstable. The breakdown of water occurs due to the ionization of water molecules, which can lead to the formation of hydrogen and hydroxide ions. This process can be accelerated by the presence of impurities or contaminants in the water. The ionization of water molecules can also lead to the formation of reactive oxygen species (ROS), which can cause oxidative stress and damage to living cells.
Applications of Water
Despite its limitations, water has numerous applications in various fields. Some of its most notable uses include:
This is a major challenge in the development of solid-state electrolytes for fuel cells and other energy storage devices.
The Challenge of Solid-State Electrolytes
A Key Component in Energy Storage Devices
Solid-state electrolytes are a crucial component in the development of fuel cells and other energy storage devices. They play a vital role in facilitating the flow of ions between the electrodes, enabling the conversion of chemical energy into electrical energy. However, the development of solid-state electrolytes has been hindered by the need for a liquid electrolyte that is highly concentrated and free of excess water. Key challenges: + Maintaining a liquid state at high temperatures + Preventing the formation of excess water + Ensuring ionic conductivity
The Importance of Concentration
The concentration of the electrolyte is a critical factor in the development of solid-state electrolytes. A highly concentrated electrolyte is necessary to prevent the formation of excess water, which can lead to a decrease in ionic conductivity. However, achieving a highly concentrated electrolyte is a significant challenge. Factors affecting concentration: + Temperature + Pressure + Composition of the electrolyte
A Breakthrough in Solid-State Electrolytes
Researchers Discover a Solution
Researchers in Empa’s Materials for Energy Conversion department have discovered a way to solve the problem of maintaining a liquid state at high temperatures while preventing the formation of excess water.
The researchers are now planning to test the system in real-world applications.
