Dear friend Luna Lopez
A liquid cell and a battery are both electrochemical systems, but they have some key differences.
A liquid cell typically consists of two electrodes (often made of metal) that are placed in a solution containing ions. The electrodes are connected to an external circuit, and when a current is passed through the cell, electrochemical reactions occur at the electrodes that lead to the transfer of electrons between them. The reactions can continue until one of the reactants is consumed, at which point the cell "dies".
In contrast, a battery typically consists of two or more cells connected together in series or parallel to provide a higher voltage or longer operating life. Each cell in a battery operates like a liquid cell, with two electrodes and an electrolyte solution. However, the electrolyte in a battery is often contained in a solid form, such as a paste or gel, which helps to reduce the risk of spills or leaks. Additionally, batteries often have additional features such as built-in protection circuits, casings, and connectors, which make them more practical for use in portable electronics and other applications.
In summary, a liquid cell is a simple electrochemical system consisting of two electrodes in a solution, while a battery is a more complex system consisting of one or more cells with solid-state electrolytes, additional features, and a longer operating life.
And can I chose whatever is the electrodes' material I want to work with in the liquid cell ? like for instance LFP or NMC with graphite ? And how can it be done regarding the small dimensions of the liquid cell ?
