Although rechargeable lithium–sulfur (Li–S) batteries promise high energy density storage—particularly attractive for electric vehicle applications—the technology is currently limited by the shuttling polysulfides between the battery’s electrodes. of its capacity after 40 hours.

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. The high lithium ion conductivity imparts excellent cycling performance, the researchers noted. Dudney, N.

Yi Cui at Stanford University have demonstrated a new proof-of-concept lithium metal-free battery with high specific energy consisting of a lithium sulfide (Li 2 S)/mesoporous carbon composite cathode and a silicon (Si) nanowire anode. A paper on the novel battery was published online 25 February in the ACS journal Nano Letters.

One of the most significant impediments to an increased market share for plug-in vehicles is the high cost of rechargeable energy storage. The new cell and BMS are intended to achieve 400Wh/kg cell energy density with practical cycle life and performance metrics. This project was led by OXIS and part-funded by Innovate UK.

A team from Japan’s RIKEN, led by Hye Ryung Byon, has developed a lithium-iodine (Li-I 2 ) battery system with a significantly higher energy density than conventional lithium-ion batteries. The high solubility of triiodide/iodide redox couples results in an energy density of ~ 0.33?kWh?kg Zhao et al. Click to enlarge.

(b) Capacity retention of sulfur–TiO 2 yolk–shell nanostructures cycled at 0.5 C, in comparison with bare sulfur and sulfur–TiO 2 core–shell nanoparticles. The authors say that, to the best of their knowledge, this is the first time that a lithium–sulfur battery with this level of performance has been described.

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. The RPI researchers first demonstrated this smoothening (healing) of the dendrites in a lithium-lithium symmetrical cell.
