Kostiantyn Kravchyk explains the chemistry in an aluminium graphite battery: With well suited graphite, the edges look like a bundle of paper. The large ions from the electrolyte can easily slip into the spaces between the sheets and settle there. If the graphite layers are bruised, this does not work so well. Image: Empa

Could we develop more sustainable technologies to save precious natural resources, besides the familiar lithium-ion batteries? The global economy's demand for lithium-ion batteries will be rising sharply in future. Electric cars depend on them, as do laptops, smartphones and power tools for the construction industry and the DIY sector. Soon an-other area will follow suit that requires rechargeable batteries at an even larger scale: the storage of renewable energy.
