(a)

Interpretation Introduction

Interpretation: The given questions based upon lithium-ion batteries are to be answered.

Concept introduction: There are lithium ion batteries that have cathodes composed of ${\text{FePO}}_{\text{4}}$ when fully charged.

To determine: The formula of cathode when the battery is fully discharged.

(b)

Interpretation Introduction

To determine: If $\text{Fe}$ is oxidized or reduced as the battery discharges.

(c)

Interpretation Introduction
