Researchers in Australia Discover Lithium Sulfur Battery That May Double EV Range

KB Electric LLC installs many different EV (electric vehicle) chargers for different types of electric vehicles, like Tesla. It’s only appropriate that we blog about new happenings for electric vehicles, since we have seen an upward trend with new EV owners within the past few years needing EV home chargers installed.

We came across a very informative article detailing new research and technological advances in cathode durability for lithium sulfur batteries. Let’s take a look…

Researchers at Monash University in Melbourne, Australia discovered how to make a stronger cathode for lithium sulfur batteries by reducing the amount of binder used to increase space for the cathodes.

Past trials at producing batteries using lithium sulfur didn’t work because the materials broke down under stress. Cathodes in sulfur batteries normally swell and contract with lithium ions during discharge cycles, and contract during charge cycles, decreasing the amount of charge and discharge cycles the cathodes can handle. This also leads to cathode corrosion, which in turn, shortens a battery’s life cycle. 

The Australian researchers say that by reducing the binder use that increases the space for the cathodes, the cathodes can accommodate change for the structure and stress, maintaining its quality over a longer cycle. The researchers predict the new batteries could have the potential to produce over a 1000km (621 mile) range.

The team is just in the research and development stage, but say within the next 2 to 4 years, the batteries could be on the market. It’s also noted that their large group cells lasted for 100 cycles. A patent is already secured for their manufacturing process as well.
