Printing creates new batteries: less than 1 gram in weight

German Research Agency Fraunhofer Research Institution for Electronic Nano
Systems (ENAS) recently demonstrated a disposable flexible battery made with printing technology at the "2009 International Nanotechnology Exhibition." The battery weighs less than 1 gram, is less than 1 millimeter thick, and contains no toxic chemicals such as mercury, so there is no need to worry about it polluting the environment.

Battery manufactured by printing

According to Prof. Reinhard Baumann, who is responsible for the research project, they used the screen printing technology that is generally used in T-shirts and logo printing to make such batteries. The battery was wrapped in plastic material. The anode was zinc, and the anode was manganese. The output voltage of a single battery is 1.5V, and the total voltage after series connection can rise to 6V.

Dr. Andreas Willert, Project Manager of ENAS, said, “Our goal is to produce this battery at a very low cost.” It is reported that the cost of this battery is only a few yen and is expected to reach the practical level in the fourth quarter of this year. . In addition, the battery life is relatively short, generally only applicable to bank credit cards, New Year cards and other products.
