Can a battery be made by spray painting?

Fabrication of batteries by spray painting requires formulation of component materials into liquid dispersions (paints), which can be sequentially coated on substrates to achieve the multilayer battery configuration.

Can battery materials be engineered into paint formulations?

In summary, battery materials can be engineered into paint formulations and simple spray painting techniques can be used to fabricate batteries directly on surfaces of various materials and of different shapes.

Can a graphite battery be used as a paintable battery?

Graphite anode or high voltage cathodes could be used to increase the nominal voltage of paintable batteries ( ∼ 3.6 V for LCO-Graphite cell). However, graphite based Li-ion batteries have safety concerns 14, 17 and LTO was chosen to ensure safer operation due to minimal risk of Li-metal plating if accidentally overcharged.

Can paint be used to build a battery?

If the components of a battery, including electrodes, separator, electrolyte and the current collectors can be designed as paints and applied sequentially to build a complete battery, on any arbitrary surface, it would have significant impact on the design, implementation and integration of energy storage devices.

Can modular spray painted battery units be connected to Energy Conversion Devices?

We also demonstrate the possibility of interconnected modular spray painted battery units to be coupled to energy conversion devices such as solar cells, with possibilities of building standalone energy capture-storage hybrid devices in different configurations.

Is a fully paintable energy storage technology possible?

Printing (or generally, painting) is already considered a viable technique for large-area fabrication of electronic devices (circuits, photovoltaics, displays, etc.) on virtually any type of substrate 12. Consequently, there is huge interest in developing a fully paintable energy storage technology.
