Maximizing Voltage from a Wet Cell Battery

[yjk91]

Homework Statement

Describe a wet cell battery and explain its operation?
How would would ensure getting maximum voltage. Assume you are only permitted a single cell.

The Attempt at a Solution

I got the first question, but i don't get how to answer the second question. i know that when a wet cell battery is in a hot climate, the water in a battery will evaporate or accumulate the chemical inside. other than this i have no idea how to answer this question. Also i think using chemical that have large potention Energy.

well if single cell means only one wet cell, then i think i can answer it.

you have to use the standard reduction potentials table to find the half reactions that will react to form the most voltage.

using the table, i get:

(1st half reaction) F_2(g) + 2e^- \rightleftharpoons 2F^- E^o = 2.87Volts

(2nd half reaction) Li_(s) \rightleftharpoons Li⁺ + e^- E^o = 3.04 volts

(Cell Redox reaction) 2Li⁺ + F_2(g) \rightleftharpoons 2F^- + 2Li_(s) E^o = 5.91 volts.

This is the highest voltage possible with a wet cell i think...well hope i helped.
