Currently Lithium-ion batteries provide various benefits over conventional batteries including charge time and weight. Li-S Energy is hoping to use lithium sulphur batteries which have a longer life, higher energy density and are even lighter than Lithium-ion batteries.

Lithium sulphur batteries can be cycled 600 cycles which is more than the current batteries. Advancement in this technology comes as a result of a joint venture between Deakin University and BNNT Technologies. Deakin University researched boron nitride nanotubes (BNNTs) which are pivotal to the advancement. Through the joint venture, BNNT Technologies will manufacturing the batteries.

BNNTs were only discovered in 1995, they are a very tough material comprising of nanotubes of Carbon, Nitrogen and Boron atoms. Until recently the challenge for these products was to develop them outside the lab and reduce the cost for them to be made.

The cost to produce the BNNT has been around $1M per kilogram, now the BNNT manufacturing facility at Deakin University’s Geelong campus has been setup to produce 50kg of BNNT per year per manufacturing module per shift.

The lithium-ion battery market is worth about $47.5 billion and is expected to double by 2025. A representative of the company would not state how many batteries could be made each year but believes the batteries would be competitive with other lithium-ion batteries.

Reducing the weight of batteries is crucial to the long-term success of EV’s and other devices. Li-S Energy believe removing the heavy elements that are in a lithium-ion batteries and are not required in lithium sulphur batteries will make the lithium sulphur battery very cost competitive considering the higher energy density.

Li-S Energy is expected to be listed on the ASX in August with an expected market cap of $544 million.
