Lithium-Sulfur (Li-S) Batteries

Lithium-Sulfur (Li-S) Batteries

Li-S batteries are gaining attention due to their ultra-high theoretical energy density (~2600 Wh/kg). Recent research has focused on mitigating polysulfide shuttling and improving cycle life. A study demonstrated a regulated electronic and ionic conductive framework using carbon nanotubes (CNTs) and sulfur-coated aramid fibers, achieving an initial capacity of 1437.6 mAh g⁻¹ and energy density of 468.6 Wh kg⁻¹

Anode-Free Lithium Metal Batteries (AFBs)

Anode-Free Lithium Metal Batteries (AFBs)

AFBs eliminate traditional anodes, using only a copper current collector, which enhances energy density. However, challenges like lithium dendrite growth remain. A recent study visualized lithium plating dynamics under pressure differences, revealing that high-pressure regions form dense lithium deposits, improving battery performance
