The suppression of lithium dendrite growth in lithium sulfur batteries: A review

•We review the recent progresses of the lithium dendrite suppression in LSBs.•Modifications of anode and electrolyte are used in improving safety of LSB anodes.•Electrolyte additive suppresses dendrite by modifying electrolyte/anode interface.•Seeking the novel separator with 3D structure will be a new route.
