DAIR Partnership Helps Solid UltraBattery Advance High-Energy Density Green Battery 

 Solid Ultrabattery is making strides to revolutionize the battery industry. Led by inventor and entrepreneur V-Bond Lee and founder Dr. Zhongwei Chen, the company has partnered with Downsview Aerospace Innovation & Research (DAIR) to advance the development of low-cost, high-energy, solid-state green batteries for the rigorous demands of aerospace applications. 

 DAIR, a non-profit consortium operating from Downsview Park in Toronto, energizes the innovation ecosystem by bringing together start-ups and high-potential businesses such as Solid Ultrabattery with leading aerospace companies and post-secondary institutions. Through the DAIR Green Fund, they share a common goal of advancing technology readiness, accelerating innovation-led growth, developing cutting-edge sectoral technology, and supporting projects that aim in greening the economy through reduced aviation emissions. 

CEO V-Bond Lee brings a wealth of experience to the project. He has successfully developed and commercialized groundbreaking methods and technologies for various industries, including aerospace, automotive, and infrastructure components. Zhongwei Chen, Ph.D., a professor in the department of Chemical Engineering at the University of Waterloo, dedicates his expertise in battery and fuel cell technology to the team. 

With funding and support from the DAIR Green Fund, Solid UltraBattery is advancing its plans to develop a lightweight 5Ah single-cell pack as a prototype to be validated with its use on a small drone. Reaching this Technology Readiness Level (TRL) 7 before the project’s completion will also help the company advance its goals to develop an all-solid-state battery by 2030. 

“The DAIR Green Fund has provided Solid Ultrabattery with a distinct opportunity to progress its energy storage technology towards commercialization in the aerospace industry. We are highly satisfied with the project’s current progress and the valuable support and networking opportunities facilitated by DAIR.”

The support and funding from DAIR have been instrumental in the company’s journey to support the development of new aerospace sectors and revolutionize the battery industry to provide a clean and sustainable economy. Green batteries offer increased performance with better energy efficiency, greater energy density, and longer life cycles while reducing weight onboard. The Solid UltraBattery innovation introduces a green battery less prone to fire and explosion than conventional batteries, making them safer to use and transport in aerospace applications while providing a greener future. 

Green batteries have significant potential to help the aerospace sector reduce its environmental impact toward meeting its global sustainability goals. The green batteries can be used as the power source for 

drones to support a range of applications, from surveillance and sensing to logistics and transportation. Whether powering electric propulsion systems for an aircraft or storing energy generated from renewable sources, green batteries can efficiently release energy during flight, support high-speed and more prolonged flights for emergencies or power equipment on the ground, reducing or eliminating the need for fossil fuel combustion engines. 

Solid UltraBattery’s solid-state green batteries can address a growing demand for safe, lightweight, high-performance batteries. In aerospace, new sectors such as drones are widely used for surveillance and reconnaissance purposes to provide real-time aerial views, gather intelligence, and monitor areas that are difficult or dangerous for humans to access. This sector can provide a platform for innovation-led businesses to test, refine, and validate cutting-edge new technologies in a cost-effective and controlled manner. 

The Solid UltraBattery team is well-equipped to develop and commercialize groundbreaking solid electrolyte green battery technology. With a 10,000 ft2 state-of-the-art facility in Guelph, Ontario, the company has cutting-edge prototype and test equipment to uphold R&D accuracy and efficiency. Recently built in Scarborough, Ontario, the company’s prototype lab has additional fabrication and cycle test equipment ready for high-quality, high-quantity battery-grade anode production, and ready to create sustainable green jobs once commercialized. 

In partnership with DAIR, Solid UltraBattery is positioned as a leading company in the energy storage industry and primed to scale-up their business to new heights. Their advancements in high-energy-density green batteries have significant sustainable potential for the aerospace sector and the economy. Focused on R&D, design, and production of cutting-edge solid-state green batteries, the team has set their sights on customers in military and security, offering energy-dense green batteries ideal for fire and rescue, coast guard, and search missions. 

Solid UltraBattery is poised to shape the future of energy storage technology. The company’s development of low-cost, high-energy, and safe solid-state batteries with high energy density has significant potential to lead the energy storage industry and produce clean energy for a greener economy. With the support of partners like DAIR and their unwavering commitment to accelerating innovation-led growth, the company is leading the way for a cleaner, greener, and more sustainable future.
