Abstract The main drawback of Lithium-Sulfur (Li-S) batteries which leads to a short lifetime, is the shuttle effect during the battery operation. One of the solutions to mitigate the shuttle effect is the utilization of interlayers. Herein, graphene oxide (GO) paper as an interlayer has been implemented between the sulfur cathode fabricated by the vapor deposition process as a binder-free electrode and a separator in a Li-S battery in order to gain a sufficient capacity. The morphological characteristics and electrochemical performance of the fabricated electrode have been investigated. The fabricated battery demonstrates an initial discharge capacity of 1265.46 mAh g-1 at the current density of 100 mA g-1. The coulombic efficiency is obtained to be 88.49% after 40 cycles. The remained capacity for the battery is 44.70% after several cycles at different current densities. The existence of the GO interlayer improves the electrochemical properties of the battery compared to the one with a pure sulfur cathode. The obtained results indicate that after 40 cycles, the capacity retention is 2.1 times more than that of the battery without the GO implementation.

The suitability of some different kinds of liquid electrolytes with a 1M solution of LiCF3SO3 was evaluated for discharging capacity and cycle performance of Li/S cells at room temperature. The liquid electrolyte component was found to have a profound influence on the discharging capacity and cycle property. The lithium–sulfur battery based on the alcohol-ether binary electrolyte shows two discernible voltage plateaus at around 2.4 and 2.1 V, which correspond to the formation of soluble polysulfides and of solid reduction products, respectively. However, the liquid electrolyte based on carbonate electrolyte shows a bad compatibility with sulfur cathode. The lithium sulfur battery can not deliver acceptable discharging capacity and cycle performances.

The development of solid-state polymer electrolytes is an effective way to overcome the notorious shuttle effect of polysulfides in traditional liquid lithium sulfur batteries. In this paper, cationic cyclopropenium based cross-linked polymer was firstly prepared with the one pot method, and then the counter ion was replaced by TFSI− anion using simple ion replacement. Cationic cyclopropenium hyper-crosslinked polymer (HP) was introduced into a polyethylene oxide (PEO) matrix with the solution casting method to prepare a composite polymer electrolyte membrane. By adding HP@TFSI to the PEO-based electrolyte, the mechanical and electrochemical properties of the solid-state lithium-sulfur batteries were significantly improved. The PEO-20%HP@TFSI electrolyte shows the highest Li+ ionic conductivity at 60 °C (4.0 × 10−4 S·cm−1) and the highest mechanical strength. In the PEO matrix, uniform distribution of HP@TFSI inhibits crystallization and weakens the interaction between each PEO chain. Compared with pure PEO/LiTFSI electrolyte, the PEO-20%HP@TFSI electrolyte shows lower interface resistance and higher interface stability with lithium anode. The lithium sulfur battery based on the PEO-20%HP@TFSI electrolyte shows excellent electrochemical performance, high Coulombic efficiency and high cycle stability. After 500 cycles, the capacity of the lithium-sulfur battery based on PEO-20%HP@TFSI electrolytes keeps approximately 410 mAh·g−1 at 1 C, the Coulomb efficiency is close to 100%, and the cycle capacity decay rate is 0.082%.
