QUESTION:

(c) Will the lithium cobalt electrode expand or contract as lithium ions are inserted?

ANSWER:

Problem 7.89c Step-by-step solution Step 1 of 5 ^(a) The size of cation is always smaller than that of the parent atom. The number of electronsdecreases the magnitude of the positive charge in the nucleus increases. The forces of 3+attraction increase and hence the size decreases. Among comparison between the ions Coand Co 4+there is one electron less in Co 4+hence the size of Co 4+is smaller than Co . 3+
