daniell cell
C1Technical, Historical
Definition
Meaning
A historical type of primary electrochemical cell that produces electricity through a chemical reaction between zinc and copper, using a porous pot barrier to separate the two electrolytes.
Any experimental setup or historical illustration based on the original design by John Frederic Daniell, now largely obsolete but used to teach foundational principles of electrochemistry, galvanic cells, and voltage production.
Linguistics
Semantic Notes
Always capitalized 'Daniell'. Used almost exclusively in educational and historical chemistry contexts. It refers to a specific, fixed design, not a general class of cells.
Dialectal Variation
British vs American Usage
Differences
Spelling is identical. Both varieties use 'Daniell cell'. The concept is equally historical in both.
Connotations
Connotes a standard example in physics and chemistry textbooks, a benchmark for historical scientific progress. No emotional connotation.
Frequency
Extremely low frequency in general language. Found almost solely in educational materials (textbooks, lab manuals) for chemistry and physics.

Mnemonic
Daniel's Pottery: Daniell used a Porous POTtery cup to separate his copper and zinc.
Conceptual Metaphor
[A TECHNICAL DEVICE does not have a common conceptual metaphor. It is understood literally as a model or source.]
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'cell' as 'ячейка' (grid cell) or 'клетка' (biological cell). The correct term is 'элемент' (гальванический элемент Даниела). Avoid transliterating 'Daniell' as 'Даниель' without the double 'l' context; established term is 'элемент Даниеля'.
Common Mistakes
- Misspelling as 'Daniel cell' (missing the second 'l').
- Using it as a generic term for any battery.
- Confusing the anode and cathode materials.
- Pronouncing it as /dəˈnaɪ.əl/ instead of /ˈdæn.i.əl/.

FAQ
Frequently Asked Questions
It was invented by the British chemist and meteorologist John Frederic Daniell in 1836.
A standard Daniell cell produces approximately 1.1 volts.
No, it is historically significant but obsolete for practical use. It is now primarily a teaching tool in science education.
It consists of a zinc anode immersed in zinc sulfate solution, a copper cathode immersed in copper sulfate solution, and a porous barrier (originally a porous pot) separating the two solutions, allowing ion flow while preventing mixing.
