Superior Battery Performance
 A new generation in ultra-light and high-performance batteries

World attention has shifted to Lithium Sulphur batteries which can perform more efficiently than Lithium-ion batteries. Using BNNT as both an integrated protective coating for Lithium anodes and as an advanced form separator in the battery architecture and chemistry, scientists acknowledge a breakthrough in creating safer, low heat, high performance batteries with extended cycle life and rapid charge capabilities. These batteries will revolutionise the performance of products such as: mobile phones, portable computers and other devices, electric vehicles, drones, handheld tools, appliances and everything else switching to battery power.

Lithium-ion batteries have reached their theoretical limit in energy density (Wh/kg), cycle life (number of recharge cycles) and process time in recharging. Meanwhile, the demand for efficient portable power sources increases every day due to the rapid development of portable devices such as mobile phones and notebook computers, as well as a large range of industry tools. Batteries are also required for electric vehicles and large-scale electrical energy storage. The world wants batteries and better batteries for more diverse product applications. In the longer-term batteries will eventually be part of powering everything electric.

Lithium Sulphur batteries address some of the problems and limitations of LI-ion batteries, but don’t present a viable alternative in large scale battery manufacture as yet. However, Lithium Sulphur BNNT batteries present the next generation super performance batteries which are safer, cheaper, lighter, longer lasting, quick to charge and more flexible in shape and size.

Deakin University, in collaboration with BNNT Technology Limited, has commenced an advanced R&D project for designing, building, testing and validating a new form of Lithium Sulphur battery incorporating BNNT’s. BNNT’s will be used as a protective coating for Lithium metal anodes. The network and excellent thermal conductivity of the BNNT layer can inhibit dendrite growth from the anode and promote significant heat dissipation which greatly improves the safety of the battery design and prevents anode degradation of the Li-S batteries. BNNT’s will also be used to improve the thermal stability and mechanical strength of polymer separators and protect cathodes. BNNT’s will be interpolated into solid-state electrolytes for flexible Li-S batteries.

The new architecture and improved chemistry in Lithium Sulphur BNNT battery design will provide industries with new opportunities for revolutionary and more sustainable electric powered products.
