Researchers in China are proposing a new strategy to retard dendrite formation on Li metal anodes in high-capacity Li-ion batteries. In a paper published in the ACS journal Nano Letters , they describe trapping Li within hollow silica microspheres with a carbon nanotube core to suppress dendrite growth. Such an electrode exhibited a dendrite-free morphology after plating 2 mA h cm –2 of Li.
