What are the electrode materials used in lithium-ion batteries?

What are the latest advances in electrode materials for rechargeable batteries?
- Herein, recent advances regarding defect engineering in electrode materials for rechargeable batteries are systematically summarized, with a special focus on the application of metal-ion batteries, lithium–sulfur batteries, and metal–air batteries.
Why do we use different combinations of metals in batteries?
- Another reason to use different combinations of metals is that often two or more battery cells need to be stacked to obtain the required voltage, and it turns out that some electrode combinations stack together much more happily than other combinations.
How can defect engineering improve the performance of batteries?
- With the in-depth understanding of the mechanisms underlying electrode reactions and the rapid development of advanced technology, the performance of batteries has significantly been optimized through the introduction of defect engineering on electrode materials.
