Podsumowanie kontekstu i ogólnych celów projektu

- Project context and objectives -
The BASMATI project acts right in the heart of the worldwide evolution of low-cost, high-throughput printed electronics. The availability of so-called functional inks with specific physical or chemical properties is key. Moreover nanoparticles are required in these ink to ensure printability. With the knowledge achieved and the pilot lines, BASMATI will pave the way for the industrial production of functional inks for mass applications.
Two axes:
1.Develop generic methodology to formulate suitable inks based on existing functional materials, for example copper or Li-ion cathodes. First, nanomaterials with suitable composition and properties are synthesized. Then, nano-inks with these active particles are formulated and optimized.
2.Install pilot lines for large quantities of nanomaterials and functional nano-inks. The effect of the most important process parameters on the upscaling is studied.
The BASMATI methodology for functional nano-ink development is applied to a concrete demonstrator case, namely a printed Li-ion battery. We develop both conductive nano-inks (copper, as electrical contacts inside the battery), and cathode nano-inks (NMC and LFP , as the active Li-ion battery material).
Two different printed battery designs and four printing technologies are considered. Nanosafety is considered. Water-based inks are developed without harmful organic solvents.

- Conclusions of the action –
*The synthesis of nano-Cu, nano-NMC and nano-LFP is in line with the BASMATI objectives. Al and Ni are no longer considered.
*The ink formulation work at lab-scale, including optimization and preparation of the upscaling, is according to objectives. The inks are developed to be compatible with high-throughput printing processes
*The pilot lines for nanomaterials and nano-inks are operational within the scope of the project objectives. The first batches have been produced successfully.
*The BASMATI consortium has printed a stacked Li-ion battery, showing good battery behavior. The industrial production process for stacked printed batteries is mostly clear
*The work has been guided by nanosafety recommendations. Water-based inks, without harmful organic solvents, have been developed.

Innowacyjność oraz oczekiwany potencjalny wpływ (w tym dotychczasowe znaczenie społeczno-gospodarcze i szersze implikacje społeczne projektu)

BASMATI overcomes technological and economic barriers to the availability of inks for printed electronics:
*Supply of low-cost conductive inks, compared to silver inks
*High availability: production of relevant quantities of functional inks
*Compatible with high definition printing: inks are developed both for high throughput (screen printing) and for high resolution (inkjet printing) printing technologies
*Nanosafety guidance is applied
*Ink formulations involving water or non-toxic solvents are formulated

The project covers two kind of nano-inks:
*Conductive inks (Cu) as a low cost alternative to silver for a large range of applications (RFID, photovoltaic, sensors, vehicles, smart packages).
*Cathode inks (NMC, LFP) for printed energy storage applications (printed electrodes, thin-film printed batteries).

The project consortium brings together the whole value chain covering nanomaterial synthesis, ink formulation, ink production, printing equipment manufacturing and end-user. Collaboration between all stakeholders in the value chain will enable a better integration of the different technologies facilitating the industrial take-up in printed devices.
