” We propose an unique Na-O2 battery design for in vivo applications that utilizes a stable sodium-based alloy as the anode and oxygen from body fluids as the cathode element. This battery demonstrates appealing capacity as an energy source for powering micro-implantable electronic devices,” the study authors keep in mind.
An issue with medical implants is that physicians have to perform invasive surgeries to change their batteries from time to time. This freshly proposed Na-O2 battery, however, would operate on our oxygen– it would recharge itself.
Did you know that very same oxygen in our bodies could one day power batteries in medical implants? A new study has revealed an unique sodium-oxygen (Na-O2) battery that does simply this.
How an oxygen-driven battery works
” The Na+ and OH ions produced throughout the discharge procedure get in the blood without causing electrolyte disruption. The metabolic process of compounds in the body did not result in any problems in the liver and kidney. The exceptional bio-compatibility of the battery suggests enormous capacity for practical applications and has the prospective to revolutionize the field of implantable batteries,” the researchers said.
After producing their novel battery, they framed this plan in a soft polymer. They then surgically implanted it under the skin in rats, which functioned as model animals for the experiment..
Revealing terrific potential.
” By further extending the implantation for 2 weeks, steady voltage plateaus of roughly 1.4 and 1.3 V were obtained at 1 and 2 mA/cm2, respectively, with an optimal power density of 2.6 μW/ cm2. After 4 weeks of implantation, the discharge voltage plateaus remained at roughly 1.3 and 1.2 V at 1 and 2 μA/ cm2, respectively, suggesting a stable and continuous O2 supply from the body fluids.”.
” If we can take advantage of the continuous supply of oxygen in the body, battery life wont be limited by the limited products within conventional batteries,” Xizheng Liu, among the research study authors and a professor of energy materials and gadgets at Tianjin University, said.
For the first time, the scientists showed that internal oxygen might offer stable energy input to batteries. The output attained throughout the research study will not be adequate to power any medical implant. For instance, a pacemaker runs on a battery capable of generating 2 to 5 volts of output.
The Na-O2 battery might be one of the most safe power options for medical gadgets when it comes to safety. During the study, it didnt trigger any side impacts in the model animals, and none of the by-products it released were hazardous to human health.
It is oxygen if there is one substance that is plentiful in mammal bodies. Oxygen is continuously being changed via respiration and is essential to many energy-centered biological procedures. So, how could we utilize this extremely bioavailable molecule in a battery? The scientists at Tianjin University of Technology were looking for the answer to this question.
” After 24 hours of implantation, an unstable discharge voltage plateau was observed at 1 and 2 μA/ cm2 indicating that only a percentage of succus or blood entered the cathode compartment and allowed a continuous O2 supply,” the research study authors keep in mind.
” While numerous essential studies and intrinsic obstacles stay to be taken on, the Na-O2 battery is still extremely appealing and can trigger a brand-new revolution in the field of implantable devices, leading to the development of brand-new techniques for the treatment of various illness.”.
The research study is released in the journal Chem.
With this in mind, they utilized a sodium-based alloy as the anode. Salt is already integral to the human diet and body, playing a key role in preserving nerves, body fluids, and muscles. All these elements make it an ideal biocompatible anode.
They wished to establish a safe, possible, and efficient oxygen-powered battery, and the only way to do this was to use chemicals and parts compatible with living systems..
As the separator, the scientists used nanoporous gold (NPG), a material that has pores a thousand times smaller sized than the width of a human hair. Due to the fact that of its biocompatibility and high stability, NPG is already utilized in many biological applications.
Therefore, more research study is needed to improve the Na-O2 battery performance, according to the study authors.
When they implanted the battery restored after some time around the implant, the scientists also saw that the blood vessels that suffered damage. This unexpected development tips that the Na-O2 battery can also be used for monitoring wound healing, according to Liu.
