Introduction to Lithium Metal Batteries and Challenges
In recent years, lithium metal batteries (LMBs) have attracted significant attention for their potential to transform energy storage systems. Their high energy density makes them suitable for powering electric vehicles and portable devices. However, challenges such as lithium dendrite formation and limited cycle durability hinder widespread adoption. A pioneering study by Chinese scientists introduces boron additives as a promising solution to these issues.
Advantages of Boron Additives in LMBs
Boron additives bring several advantages to lithium metal batteries. The electron-deficient nature of boron aids in dissolving Li2O, which substantially lowers the interfacial charge transfer resistance at the lithium metal anode. This leads to improved efficiency by facilitating better ion movement across the electrode interface. Moreover, boron promotes the dissolution of LiF deposits within CFx pores, increasing the lithium-ion diffusion coefficient and resulting in higher discharge capacities suitable for high-rate applications.
