(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.

Battery cycling data for poly(S-r-DIB) (10 wt% DIB, C/10 rate). A University of Arizona-led international research team has developed a simple process for making lightweight plastics from elemental sulfur; the team has successfully used a new polymeric sulfur produced via the process as an electrode material for lithium-sulfur batteries.

Researchers at the University of Waterloo in Canada have developed electrode materials for Lithium-Sulfur batteries using a conductive mesoporous carbon framework that have demonstrated reversible capacities of up to 1,320 mAh g -1. Carbon electrodes help form high capacity lithium-sulfur batteries ( Chemistry World ).

optioned a PNNL-developed method for building titanium oxide and carbon structures that greatly improve the performance of lithium-ion batteries. The new material stores twice as much electricity at high charge/discharge rates as current lithium ion batteries, and creates increased battery capacity and a longer cycle life.

A team at the University of Michigan (U-M) has used operando video microscopy to develop a comprehensive understanding of the voltage variations observed during Li metal cycling, which is directly correlated to dendrite growth. However, the Li-metal electrodes in these next-generation batteries are especially prone to forming dendrites.

The second round was focused specifically on three areas of technology representing new approaches for advanced microbial biofuels (electrofuels); much higher capacity and less expensive batteries for electric vehicles; and carbon capture. This process is less than 1% efficient at converting sunlight to stored chemical energy.

In 2012, the US Department of Energy (DOE) awarded $120 million over five years to establish a new Batteries and Energy Storage Hub known as the Joint Center for Energy Storage Research (JCESR). The goal is a battery five times more powerful and five times cheaper within 5 years. Earlier post.) Crabtree (2015) Click to enlarge.
