The Properties of Water
Water is a unique substance with several distinct properties that make it an essential component of our daily lives. Its chemical stability is one of its most notable features, but it also has some significant drawbacks.
Conductivity and Ionization
Water is an excellent conductor of ions, which means it can carry electrical charges. This property makes it an ideal substance for various applications, including:
Chemical Stability
Water’s chemical stability is its most notable feature. It can withstand high temperatures and pressures without breaking down or reacting with other substances. This property makes it an ideal substance for various industrial applications, including:
Limitations
Despite its many properties and applications, water has one major drawback: it is chemically stable only up to a voltage of 1.23 volts. This means that if the voltage exceeds this limit, water can break down and react with other substances. This limitation has significant implications for various applications, including:
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
Solid-state electrolytes are a crucial component in the development of fuel cells and other energy storage devices. They are responsible for facilitating the flow of ions between the electrodes, allowing the device to generate electricity. 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. The electrolyte must be liquid to facilitate the flow of ions, but it must also be highly concentrated to prevent the formation of water, which can lead to a decrease in the device’s efficiency. The electrolyte must be free of excess water to prevent the formation of hydroxide ions, which can also lead to a decrease in the device’s efficiency.*
The Problem with Current Electrolytes
Current electrolytes used in fuel cells and energy storage devices are often liquid and contain excess water, which can lead to a decrease in the device’s efficiency. This is because the excess water can react with the electrodes, leading to a decrease in the device’s performance. The use of liquid electrolytes can lead to a decrease in the device’s efficiency due to the loss of ions and the formation of hydroxide ions.
The researchers are now looking to scale up the technology to make it more practical for real-world applications.

The Challenges of Scaling Up
Scaling up the sodium ion battery technology poses several challenges.
Step 1: Understanding the SCCER HaE initiative
The Swiss Competence Center for Heat and Electricity Storage (SCCER HaE) is a national initiative led by the Paul Scherrer Institute (PSI). This initiative focuses on exploring novel heat and electricity storage concepts, aiming to develop innovative solutions for the storage of thermal and electrical energy.
