Positive or Negative Anode/Cathode in Electrolytic/Galvanic Cell
$begingroup$ @user2612743 In an electrolytic cell you are the person that determines which electrode is positive and which is negative via the external potential. And this external potential doesn''t get altered in the course of the reaction because the "sucked in" electrons are transported away by the voltage source.
Electrode Materials for Sodium-Ion Batteries: Considerations
A sodium-ion battery consists of a positive and a negative electrode separated by the electrolyte. During the charging process, sodium ions are extracted from the positive (cathode) host, migrate through the electrolyte and are inserted into the negative (anode). In the discharging process, the reverse process takes place.

16.2: Galvanic cells and Electrodes
Positive charge (in the form of Zn 2 +) is added to the electrolyte in the left compartment, and removed (as Cu 2 +) from the right side, causing the solution in contact with the zinc to acquire a net positive charge, while a net negative charge would build up in the solution on the copper side of the cell.
Positive electrode active material development opportunities through carbon addition in the lead-acid batteries…
To address these challenges, carbon has been added to the conventional LAB in five ways: (1) Carbon is physically mixed with the negative active material; (2) carbon is used as a major active material on the negative side; …
Fundamental methods of electrochemical characterization of Li …
The battery performances of LIBs are greatly influenced by positive and negative electrode materials, which are key materials affecting energy density of LIBs. In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the …
How a battery works
Either their electrodes become depleted as they release their positive or negative ions into the electrolyte, or the build-up of reaction products on the electrodes prevents the reaction from continuing, and it''s done and dusted. The battery ends up in the bin (or hopefully the recycling, but that''s a whole other Nova topic). But.
Advances in Structure and Property Optimizations of Battery …
In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed. For …
Understanding Interfaces at the Positive and Negative Electrodes …
However, the interface stability of sulfide-based electrolytes toward active materials (neg. or pos. electrodes) is known to be lower than that of oxide-based electrolytes. In this work, we investigate the interface stability of argyrodite toward several pos. electrode materials: LiCoO2, LiNi1/3Co1/3Mn1/3O2, and LiMn2O4.

Designing better battery electrolytes
You need a positive electrode, you need a negative electrode, and — importantly — you need an electrolyte that works with both electrodes. An electrolyte is the battery component that transfers ions — charge-carrying particles — back and forth between the battery''s two electrodes, causing the battery to charge and discharge.

What is an Electrode? (with pictures)
In the case of a direct (DC) current, electrodes come in pairs, and are known as anodes and cathodes. For a battery, or other DC source, the cathode is defined as the electrode from which the current leaves, and the anode as the point where it returns. For reasons that are historical rather than scientific, electricity in a circuit is, by …
BU-104b: Battery Building Blocks
The electrode of a battery that releases electrons during discharge is called anode; the electrode that absorbs the electrons is the cathode. The battery anode is always negative and the cathode positive. This appears to violate the convention as the anode is the terminal into which current flows.
