Ultracapacitors for IoT devices


NAWA Technologies’ next-generation ultracapacitors offer large benefits in operational lifetime, cost, efficiency, safety and environmental impact.

NAWA Technologies’ NAWACap ultracapacitors are based on carbon and use a material that is abundant, recyclable and environmentally friendly. The NAWACaps can be packaged into small, flat cells and withstand extremes of temperature and the harshest environments, through deep sea to deep space. They also match ideally with the IoT sensor power use profile, coping with high current peaks, combined with long lifetime and therefore do not need to be replaced.

Combining our NAWACap ultracapacitors with a lithium cell, creating a ‘hybrid’ battery, has many advantages. If we take a GPS tracking device as an example, often used to track valuable assets or integrated into the collar of a pet, the conventional approach is to use a non-rechargeable AA lithium battery, but this is very bulky,” continues Ronald De Graaf. “Integrate NAWACap and you could immediately reduce the reliance on lithium AA to AAA-sized batteries with superior performance, including the same or even an extended operational lifetime. One could also combine NAWACap with a coin cell resulting in an even flatter, lighter package with even better lifetime.”

In addition, they are able to operate under extreme conditions, making them an excellent solution for remote applications or in the cold supply chain, keeping food temperature efficiently monitored during transportation, substantially reducing losses and resulting in better quality food for us all.”

NAWA Technologies’ core market is the production of its next-generation ultracapacitor cells. With development completed, and 13 M€ funding already raised from historical and new investors end of 2019, NAWA Technologies begins the mass production phase over the coming year. A first of its kind cell production line will be installed at its Provence facility and, at full production, NAWA expects to achieve a capacity in excess of one million cells per month.

In addition to the IoT markets, these cells will be first used globally in a wide range of electrical systems including power tools and automated guided vehicles.

Other key markets are the automotive industry in hybrid cars, battery electric vehicles (BEVs) and fuel cell vehicles (FCEVs) where NAWA Technologies can, for example, rapidly store (and deploy) energy from regenerative braking systems, greatly increasing energy efficiency. With the global market for ultracapacitors estimated to grow to €2-3bn in 2023, NAWA Technologies is ideally positioned to take advantage of increased demand.
