Structural

Supercapacitors and
Batteries

Lightweight energy storage is vital to environmentally-friendly transport , including electric vehicles , drones , and wearable devices . Structures that can simultaneously carry load and store electrical energy , while simultaneously providing an energy density equivalent to the current state-of-the-art supercapacitors or batteries , are critical enablers for these new technologies .

Competitive Advantage

• The current bottleneck preventing the production of structural energy storage devices is the development of a stiff and strong material – one that also exhibits the high ionic conductivity required to facilitate the electrochemical processes inherent in common energy storage devices , such as batteries and supercapacitors
• Development of structurally strong batteries and supercapacitors
• Ability to integrate energy storage into the load bearing capability of a transport structure , eliminating or reducing the need for a traditional energy storage device and its weight from the platform
• Significant weight savings in autonomous vehicles resulting in improved energy efficiency for direct energy requirements , and embedded communications and sensing technologies that allow energy to serve other applications for greater overall capability

Successful Applications

• Demonstration of the first generation of structural batteries by embedding flexible lithium-ion batteries into laminated fibre composites . The resulting structure can simultaneously store electricity and carry load .
