Freestanding silicon anode design improves fast charging and cycle life in lithium-ion batteries

Silicon has long been seen as a promising anode material for next-generation lithium-ion batteries because it can store much more lithium than graphite. But silicon also expands and contracts sharply during charging and discharging, which can crack the electrode, disrupt electrical pathways and shorten battery life.
