Changing the paradigm with the green, long-lasting & fast recharge liquid batteries

Product &

BETTERY aims at bringing a green liquid battery into the market, with the highest specific energy and safety associated with the lowest cost ever reported. Our battery, called NESSOX (NEw Semi-Solid flow lithium OXygen battery), is a patented technology based on lithium metal as anode and O2-rich flowable electrode as cathode.

NESSOX presents the following advantages compared to other battery chemistry already on the market or under development: higher-energy density, safety and environmental sustainability due to the absence of critical elements and heavy metals, and high safety level thanks to the thermal stability of the electrolyte. NESSOX technology combines in one system the lightness of the lithium/air batteries and the flexibility and modularity of the redox flow batteries, becoming the future reference battery technology for many vertical markets.

Our technology can be applied wherever there is a need of high energy in a small space with freedom to design the power, while safety is a must: it can be customized to be place at service for your house, in a block of flats, to power off-grid system connected with renewable energy sources or to store energy in a large ship.

Energy density

200% > Best performing Li-ion batteries on the market

NESSOX has a specific energy of 500 Wh kg-1, 2 times higher than the best currently available commercial batteries (laboratory proven). This result is achieved by the use of light elements such as lithium and oxygen.


Designed on customer's needs

Thanks to its design derived from Redox Flow Battery, energy and power can be designed and sized independently. This feature open the possibility to adapt the system to any situation and tailor the perfect solution for the customer.


Less than 150 $/kWh
30% less than Li-ion batteries

NESSOX battery lowers the costs of energy storage and production of electricity from renewable sources. NESSOX also allows the storage of energy from intermittent and non-programmable sources, supplying the energy to the grid and utilities in a controlled and efficient way.


Carbon footprint reduced by 20% kg CO2eq, heavy-metals free, low impact manufacturing

Avoiding heavy metals and costly electrode processing procedures used in conventional lithium batteries, NESSOX battery also represents a green solution for energy storage.

NESSOX brings to a radical paradigm shift:
it stores energy in a controlled way from renewable sources and becomes a charging point.


BETTERY is an Italian Innovative Startup founded in January 2018, Spin-off of the Alma Mater Studiorum Università di Bologna.

A change of paradigm in energy storage and distribution for a new, sustainable circular energy economy is necessary and we have the solutions. BETTERY team transforms disruptive research into innovative technologies, responding positively to the current global sustainability challenges and creating profitable business.

BETTERY project was originally born in the Laboratory of Electrochemistry of Energy Materials (LEME) at the Department of Chemistry “Giacomo Ciamician” of the Alma Mater Studiorum Università di Bologna, where research on materials and devices for energy (lithium and post-lithium batteries, fuel cells, supercapacitors) has been carried out through national and international collaborations for more than thirty years. We are four cofounders, Dr Alessandro Brilloni, Prof Francesca Soavi, Dr Francesca De Giorgio and Dr Alessandro Pastore.
