text: In a device which absorbs energy of charge (such as recharging a battery), the cathode is negative (electrons flow into the cathode, and charge flows out of it), and in a device which provides energy (such as battery in use), the cathode is positive (electrons flow into it and charge flows out):

text: Although the cathode is commonly known as the negative electrode, this is merely a common characteristic and not a true definition.
text: The cathode can be negative like when the cell is electrolytic (where electrical energy provided to the cell is being used for decomposing chemical compounds); or positive as when the cell is galvanic (where chemical reactions are used for generating electrical energy).
text: If the electrochemical cell is electrolytic, meaning it is supplied with electrical energy in order to break down chemical compounds, its cathode is negative.
text: Here, the cathode is negative as the electrical energy that is supplied to the cell results in the decomposition of chemical compounds.
text: However, the cathode can be negative in electrolytic cells and positive in galvanic cells.
text: In a device which consumes power, the cathode is negative, and in a device which provides power, the cathode is positive: ⁕In a discharging battery or a galvanic cell the cathode is the positive terminal since that is where the current flows out of the device.
text: The author, or authors, took the right approach to explain why a cathode can be positive or negative (respect to the other electrode).
text: This is how vacuum diodes work in the first place; it's the cathode that is heated and which therefore emits electrons which move to the anode under the influence of an electric field pointing from anode to cathode (thus, cathode is negative), while the anode doesn't emit any electrons because it's cold, and the electric field prevents electrons from escaping.
text: However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative.
text: However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative.
text: Nonetheless, in an electrolytic cell, the anode is taken to be constructive while the cathode is now negative.
text: In an electrolythic cell the anode is positive and the cathode is negative.
text: Cations migrate to the cathode so cathode is considered to be negative.
text: The "odd" part is that the signs on the cathode and anode in an electrolytic cell are the opposite way, the cathode is negative (-), and the anode is positive (+).
text: The cathode in an electrolytic process is considered to be negative, so there is actually no contradiction.
text: Therefore, cathodes must be negative.
text: Anode is positive and cathode is negative.
text: The cathode supplies electrons to the positively charged cations which flow to it from the electrolyte (even if the cell is galvanic, i.e., when the cathode is positive and therefore would be expected to repel the positively charged cations; this is due to electrode potential relative to the electrolyte solution being different for the anode and cathode metal/electrolyte systems in a galvanic cell).
text: However, it can also be positive as in the case of a galvanic cell where a chemical reaction leads to the generation of electrical energy.
text: In a device which consumes power, the cathode is negative, and in a device which provides power, the cathode is positive: ⁕In a discharging battery or a galvanic cell the cathode is the positive terminal since that is where the current flows out of the device.

text: The author, or authors, took the right approach to explain why a cathode can be positive or negative (respect to the other electrode).
text: anodes and cathodes are defined by their relationship between the source of the electrical energy, and the thing which receives that electrical energy. on the source of the electrical energy, the anode negative, while the cathode is positive,and on the thing which receives electrical energy the polarities are opposite.
