Power batteries that imitates human intestine
With the technological advancement that is happening at the moment, the one thing that is constantly holding us back is the energy source. Usually, we use Lithium-ion batteries to power our devices, e.g. smartphones and laptops, but this batteries are usually expensive and not as robust as other rechargeable batteries. One possible replacement for lithium ion batteries are the lithium sulfur batteries. Generally, these batteries contains up to five times the energy density that the lithium ion batteries contain but it degrades faster. With the new technology developed by the researchers from the University of Cambridge, lithium sulfur batteries might be the new trend for portable energy source.Using the concept similar to the human intestine, the researchers were able to create a prototype of the lithium sulfur battery which degrades at the same rate of lithium ion battery. When the lithium sulfur battery discharge, the sulfur at the cathode will absorb the lithium from the anode. Thus creating a chain like structure called poly-sulphides. After several charge-discharge cycle, this poly-sulphide structure starts to degrade. This is where the concept of human intestine enters. The researcher developed a lightweight nanostructure material that resembles the villi in the intestine. This villi-like structure is made from tiny zinc oxide wires and will act like a net, catching the poly-sulphide structures who fell off to reduce the degradation rate. This technology could potentially improve the battery life of the devices produced in the future. But unfortunately, this research is still a concept and may take years to become reality.
