Li‑S Energy has solved the critical failure mechanisms that have long plagued lithium sulfur batteries through breakthrough nanotechnology. Born from a collaboration between Deakin University's advanced nanomaterials research and BNNT Technology's cost-effective manufacturing capabilities, the company has developed lightweight lithium sulfur batteries with cycle life approaching lithium ion performance. Li‑S Energy is now scaling these revolutionary batteries to accelerate the global transition to carbon zero.
The demand for batteries is expected to increase 10x by 2030 due to climate change driving the move to renewable energy and electric vehicles^. The GWh demand from EVs alone is forecast to grow more than five times by 2025, and more than 50 times by 2040.

Global climate change targets are driving a once-in-a-century shift to electric vehicles: cars, trucks, buses and more.
Safe, light batteries with a high energy density are critical to make e-aviation viable.
Demand is expected to nearly double in the next ten years.
Lithium sulfur is superior to lithium ion in many ways.
More than twice the gravimetric energy density and improved volumetric energy density compared to Li-ion
Meaning drones, electric planes and EVs can travel twice as far with the same weight

In addition to our breakthrough lithium sulfur technology, our scientists are able to use the same Li-nanomesh™ nanocomposite to enhance a second revolutionary battery: lithium metal.
This battery type has a unique advantage in that while it doesn’t quite match the energy density of lithium sulfur, it can accommodate higher power draws — a quality favoured by electric cars, scooters and multi-prop drones.
Boron Nitride Nanotubes (BNNTs) are an advanced nanomaterial with unique physical properties. NASA has identified it as a key nanomaterial that may even help humans reach Mars, due to its strength and radiation absorption properties. We take advantage of its physical strength, thermal conductivity and electrical resistance as well as some unique electrochemical properties to enhance our lithium sulfur and lithium metal batteries
Historically, BNNTs have been very difficult to make in high purities and at high volume — and were expensive — so were disregarded as a solution for many real-world problems, including battery electrochemistry.
However, in 2020 Australian company BNNTTL successfully commissioned a high volume BNNT production facility, commercializing Deakin University’s patented BNNT manufacturing technology and know-how.
Now, through our partnership with BNNTTL, Li-S Energy not only has all the BNNT required to commercialise Li-S technology, but also exclusive distribution rights to sell BNNTs to other battery manufacturers.
