Introduction
A membrane-less electrolysis using biphasic liquid media is gaining a great deal of attention in the research field in recent years. This process is also known as transition electrode or liquid-liquid biphasic decomposition. It is a relatively simple and versatile method which offers a wide range of potential applications in lithium-ion batteries or other secondary systems.
Background
Membrane-less electrolysis using biphasic liquid media refers to a way of using a heterogeneous reaction in a two-phase system to split water. The reaction does not require any membranes, as the two phases serve as a barrier between the two reactants. In this process, the reactants must have different polarities in order to create a reaction. For example, when a cationic species, such as protons from sodium chloride, is introduced into a catholytic species, such as an aqueous solution of Sodium Hydroxide, an oxidation reaction occurs. The results of this reaction are two components with different electrochemical potentials, which can be harnessed for power.
Advantages
One of the main advantages of this process is that it is relatively simple and versatile. This process offers a wide range of potential applications, and can be used in combination with conventional electrolysis techniques. Additionally, this process can be used in conjunction with secondary systems, such as lithium-ion batteries.
The second main advantage of this process is that it is cost-effective. This method requires very little energy to reach the desired equilibrium state. Furthermore, this process is highly efficient, due to its ability to reach the highest degree of efficiency with low current densities.
Thirdly, this process has been shown to be environmentally friendly. It is a green process, since it uses a heterogeneous reaction, which leads to decreased greenhouse gas emissions. Additionally, the process does not require the use of acids or hazardous chemicals, and the materials used are non-toxic.
Disadvantages
The main disadvantage of this method is that it is not yet as well-developed and as efficient as traditional electrolysis processes. It also requires expensive equipment, such as a biphasic liquid media and a hydrogenator, which can both be expensive. Additionally, this process is not suitable for large-scale applications, such as commercial-scale electrolysis.
Conclusion
Membrane-less electrolysis using biphasic liquid media is a promising new process that offers various advantages. It is relatively simple and versatile, and can be used in combination with traditional electrolysis processes. It is also cost-effective and environmentally friendly. However, it is still not as efficient as traditional electrolysis processes, and is not suitable for large-scale applications.
