Recently, the team of Wang Yonggang and Peng Huisheng of Fudan University developed a new type of bendable battery, which focuses on the mechanical stress requirements of wearable electronic devices and the safety requirements of implanted devices
.
Wang Yonggang said that current batteries, such as lithium-ion batteries used for medical implants, are usually rigid.
In addition, most flexible batteries use flammable or corrosive electrolytes, which pose both safety risks and poor biocompatibility with wearable devices, let alone implantable batteries
.
The researchers designed two flexible batteries: a 2D ribbon battery and a 1D fiber battery
.
The former can adhere a thin electrode film to a stranded wire mesh, while the latter can embed nanoparticles
of electrode material around a carbon nanotube skeleton.
In addition to testing the biocompatible liquid, the researchers also tested the suitability of sodium sulfate as a liquid electrolyte for use in wearable device batteries
.
The results show that when using sodium sulfate solution as the electrolyte, the capacity and output power of the two new batteries are better
than most of the lithium-ion batteries currently reported for wearable devices.
