Scientists have developed a new prototype battery inspired by the anatomy of the human intestine, and the biologically informed approach could pave the way for much more powerful energy sources for our digital devices.
The prototype – which offers up to five times the energy density of the lithium-ion batteries we use in smartphones and laptops – uses a lithium-sulphur cell instead, and its intestine-mimicking design could finally make these energy-dense batteries long-lasting enough for commercial use.
