The performance of Li-ion batteries has significantly increased over the last decade, thanks to the immense R&D invested and rapid adoption of electric mobility. However, conventional Li-ion batteries with intercalation chemistry have reached the maximum theoretical capacity possible. To suffice for the exponentially rising demand for fast and easy energy storage, newer materials must be utilized to replace the limited materials in current battery technology. Today’s batteries exclusively contain a graphite anode with a low theoretical capacity because of its non-reactive dead carbon. To solve this, it was realized that pure metal electrodes such as lithium metal provide 10 times more theoretical specific capacity than graphite ones, leading to a higher energy density Li-ion battery.
