which and from which Li ions can migrate, they can be compared
to some kinds of “lithium storage containers.” On the other hand,
the electrolyte, commonly organic solvents (e.g., LiPF
, which
has been widely adopted in the manufacture of commercial
lithium-ion batteries [however, solid electrolytes, including
polymers and other inorganic materials, may also be used]),
provides paths for the migration of Li ions as well as the

),
Li ions migrate between the anode and the cathode through
the electrolyte.
