You need a positive electrode, you need a negative electrode, and — importantly — you need an electrolyte that works with both electrodes. An electrolyte is the battery component that transfers ions — charge-carrying particles — back and forth between the battery’s two electrodes, causing the battery to charge and discharge.
This review presents a new insight by summarizing the advances in structure and property optimizations of battery electrode materials for high-efficiency energy storage. In-depth understanding, efficient optimization strategies, and advanced techniques on electrode materials are also highlighted.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
