Conventional Lithium-Ion Batteries
We start with a quick review of how conventional lithium-ion batteries work. As shown in the figure below, a lithium-ion battery consists of three main layers: A cathode, or positive electrode, consisting of a lithium containing mixed-metal oxide material; an anode, or negative electrode, consisting of carbon or a mix of carbon and silicon; a separator, an electrical insulator made of a porous polymer material; and an electrolyte, the medium through which lithium ions move through the battery, typically consisting of a hydrocarbon solvent and dissolved lithium salt. (In this document, we will use “carbon anode” to mean either a pure carbon anode or a hybrid carbon-silicon anode.)
