The research is described in an online paper entitled ‘Interconnected hollow carbon nanospheres for stable lithium metal anodes’ published in Nature Nanotechnology. Lithium metal is an optimal choice as an anode material for batteries with higher energy storage density than existing lithium ion batteries because it has the highest specific capacity (3,860 mAh g–1) and the lowest anode potential of all. However,
