Printing is a popular technique used for various reasons when it comes to batteries. One of the main advantages is the ability to create special electrode structures. Additionally, screen printing is a cost-effective method for mass production of batteries, making it an efficient choice for manufacturers. Another benefit is the flexibility it provides in terms of battery shapes and sizes.

Our approach integrates screen, aerosol, and inkjet printing technologies to improve ion transport and regulate thermal conditions in printed lithium-ion batteries. This will enable batteries to achieve faster charging times and improved safety standards.
