SHENYANG, July 23 -- Chinese scientists have developed a new technique to make high-safety and scalable planar microbatteries.

The scientists of the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences developed a low-cost and highly efficient scalable screen printing technique that can help make the high-safety and scalable planar Zn//MnO2 microbatteries.

More and more electronic devices are becoming more lightweight, flexible and wearable, thus greatly boosting the demand for miniature energy storage devices.

Scientists have focused on the research of the safe flat microbattery for a period of time. In order to improve safety, the researchers developed high-safety aqueous electrolytes to replace flammable organic electrolytes to produce high-safety microbatteries.

Prof. Wu Zhongshuai, the chief scientist leading the research, found that the new batteries are not only more environmentally friendly and safe but more durable.

The microbattery has corrected the shortcomings of traditional batteries such as bulkiness, poor mechanical flexibility and easy separation of the interface under the bending state, said Wu.

The research result was published in the latest issue of the National Science Review.
