EE 292X (CEE 292X)

We will discuss the characteristics that define a battery, such as energy density, safety, and efficiency. Materials properties determine the operating envelope of the batteries, such as temperature. Popular positive electrode chemistry for lithium-ion batteries will be reviewed.

We will introduce the four main components of a battery: positive electrode, negative electrode, electrolyte, and current collector. A battery is classified by the phase of the electrode, electrolyte, energy carrier and type of chemical reaction. We will briefly introduce lithium-ion, solid-state, liquid metal, sodium sulfur and lithium air battery chemistries. Finally, we will discuss charging and discharging characteristics.
