Electric Cars to Be Able to Travel up to 2000 km on a Single Charge

Australia-based Brighsun New Energy has developed a completely new lithium-sulfur battery.

Such batteries exceed lithium-ion analogues in energy density by 5-8 times and can provide electric cars with a drive range of up to 2000 km on a single charge. Their durability is quite striking because it is 2 million km or 1700 full charging cycles. This is a real revolution in the electric car industry.

Besides, the development which took almost 8 years is not just a set of formulas on paper but a completely ready-made project. It is intended to be put to industrial testing in the near future. If they are successful, the first batteries may come off the assembly line next year.

The Li-S technology has previously been studied by other companies in the US, Germany, Korea and China. However, scientists encountered some difficulties, including volume expansion of cathode materials during cycling, the shuttling effect of polysulfides, and the dendritic growth of lithium on the anode. This results in shorter cycling life and poor fast charging capability.

Brighsun New Energy was able to eliminate all the above problems, so there are no barriers to the start of production testing. In addition, the production costs, as well as the materials themselves, are much cheaper than those of lithium-ion analogues. Such batteries will not only provide an impressive drive range for electric cars but will also give an impetus to reduce their cost.
