China energy storage net news: recently, Mr. Wang fudan university team and Peng Huisheng team developed a new type of battery, flexible design focused on wearable electronic equipment of mechanical stress on the demands and the safety of the implants.The research is published in the journal chemistry.
"Current batteries, such as lithium-ion batteries for medical implants, are usually rigid."Mr. Wang said, "in addition, most of the flexible use of flammable or corrosive battery electrolyte, both the security risks, and the biological compatibility with wearable devices is poor, not to mention the implanted cells."
The researchers designed two flexible batteries: a 2D strip battery and a 1D fiber-like battery.The former can attach a thin electrode membrane to a steel wire mesh, which can be embedded in a carbon nanotube skeleton surrounded by nanoparticles of electrode material.In addition to testing biocompatible liquids, the researchers tested the applicability of sodium sulfate as a liquid electrolyte for wearables batteries.
The results showed that the capacity and output of the two new batteries were better than the majority of the lithium-ion batteries currently reported in wearable devices when using sodium sulfate solution as electrolyte.
In addition, the 1 d battery can accelerate the carbon nanotubes will be converted to hydrogen ions dissolved oxygen, a process that if uncontrolled threatens the effectiveness of the battery, but it has the potential for the treatment of cancer, and bacterial infection.
"We can implant these fibrous electrodes into the human body to consume basic oxygen, especially those that are difficult to reach.We hope to further study this hypothesis with biologists and medical scientists.""Said wang yonggang.
