Fast Charging of Lithium‐Ion Batteries: A Review of Materials Aspects

🤖 Plain-English Summary

Abstract Fast charging is considered to be a key requirement for widespread economic success of electric vehicles. The advantages and disadvantages of typical LIB materials are analyzed, resulting in suggestions for optimum properties on the material and electrode level for fast‐charging applications.

🔑 Key Findings

• Current lithium‐ion batteries (LIBs) offer high energy density enabling sufficient driving range, but take considerably longer to recharge than traditional vehicles.
• Multiple properties of the applied anode, cathode, and electrolyte materials influence the fast‐charging ability of a battery cell.
• In this review, the physicochemical basics of different material combinations are considered in detail, identifying the transport of lithium inside the electrodes as the crucial rate‐limiting steps for fast‐charging.
