Discussion Overview

The discussion centers around the concept of liquid batteries, specifically inquiring about their characteristics and applications. Participants explore different types of batteries, including flexible and liquid-based designs, and reference specific examples and technologies.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks clarification on the concept of liquid batteries.
  • Another participant provides a link to a general overview of lead-acid batteries, which may not directly address the inquiry.
  • A participant specifies interest in a particular type of battery used in a flexible phone model, suggesting a misunderstanding of the term "liquid battery."
  • Some participants express skepticism about the existence of the mentioned technology, suggesting it may not be well-defined or recognized.
  • One participant proposes that liquid batteries could involve a liquid redox couple, mentioning soluble iron/soluble chromium flow batteries and a recent development using vanadium as a redox couple.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definition or existence of liquid batteries as described, with multiple competing views and uncertainties present in the discussion.

Contextual Notes

Some assumptions about the nature of liquid batteries remain unaddressed, and there is a lack of clarity regarding the specific technology referenced by the initial inquiry.

hi can anyone tell me the concept of liquid batteries.
 
Chemistry news on Phys.org
i m not asking about normal batteries i m taking about the one being used in nokia 888 it is a slim paper like phone which can be even folded like paper..
 
They are probably referring to a battery in which the electrodes are replaced by a liquid redox couple. One example of this is the soluble iron/soluble chromium type liquid flow batteries. The two solutions are separated by a membrane that keeps separate the two solutions (a redox couple). A recent development uses vanadium II/vanadium III as the redox couple.
