Researchers at Oak Ridge National Laboratory (ORNL) have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies. C, which is 8 orders of magnitude higher than that of Li 2 S (lithium sulfide). Earlier post.).

One of the major issues hobbling the commercialization of high energy-density lithium-sulfur batteries is the “polysulfide shuttle”—the shuttling of polysulfide ions between the cathode and anode. Top: Schematic of the electrochemical processes in a generic lithium-sulfur battery. C = Charge, D = Discharge.

Researchers at Rensselaer have developed a new technique using heat to enable self-healing lithium-metal anodes to eliminate dangerous dendrite buildup, paving the way for higher energy density battery technologies. This surface diffusion heals the dendrites and smoothens the Li metal surface. —Li et al. Click to enlarge.
