Expert Answer:

Dear student,

In metal wires outside the battery, the real particle flow is only from negative to positive. But inside the battery's wet electrolyte, the charge-flow goes in two opposite directions at the same time. (And if we built a circuit from hoses full of salt water, with no metal conductors used, then all the current would be bi-directional.)

Hope this helps.
