A brief review on the molecular engineering of sulfur‐providing materials and their impacts on the final electrochemical performance of Li‐S batteries is presented. The intrinsic physiochemical properties of active material (i.e., sulfur) play a significant role in determining the conversion behaviors of sulfur species in Li‐S chemistry. Finally, the perspectives on the challenges of molecular engineering of sulfur for achieving advanced Li‐S batteries are discussed. Some new‐type inorganic sulfur‐equivalent active molecules with beneficial electrochemical properties for cathode application are also included. This review summarizes the recent advancements in tailoring the electrochemical performance of Li‐S batteries through engineering the molecular structures of sulfur‐providing materials themselves, such as by heteroatom doping, skeleton grafting, and construction of polysulfides‐based functional intermediates. As a core element in Li‐S chemistry, the intrinsic physiochemical properties of sulfur have predominant impacts on the final battery performance, and thus rational engineering of its structure at the molecular level may provide ample possibilities to optimize the sulfur conversion behaviors and hence to promote the commercialization of Li‐S technology. The practical implementation of lithium‐sulfur (Li‐S) batteries is greatly hampered by the low sulfur utilization and limited battery lifespan stemming from the complexity of the sulfur conversion reactions. The speed, ease, versatility, safety, and green nature of this process offers a more potential future for inverse vulcanization, and enables further unexpected discoveries. The resulting polymers show thermal and light induced recycling. Compared with thermal synthesis, the mechanochemically synthesized products show enhanced mercury capture. Successful generation of polymers using crosslinkers ranging from aromatic, aliphatic to volatile, including renewable monomers, demonstrates this method is powerful and versatile. Here, we report an alternative route for inverse vulcanization-mechanochemical synthesis, with advantages of mild conditions (room temperature), short reaction time (3 h), high atom economy, less H2S, and broader monomer range. However, the process usually requires high temperatures (≥159 ☌), and the crosslinkers needed to stabilize the sulfur are therefore limited to high-boiling-point monomers only. Survey crew - adds all Scavenging locations to the map of a specific terrain.ĭog and buggy - unlocks Chum's Buggy which is used for finding minefields.Inverse vulcanization, a sustainable platform, can transform sulfur, an industrial by-product, into polymers with broad promising applications such as heavy metal capture, electrochemistry and antimicrobials. Scrap crew - when you're not playing the game, Scrap is automatically collected and will be given to you once you turn the game on (online mode required). Stockpile - further upgrades (3 levels) are increasing the aesthetical look of the Stronghold. Oil well - refills the fuel in Magnum Opus vehicle.Ĭleanup crew - the Scrap from each destroyed vehicle (on the territory where Stronghold with this upgrade is located) will be gathered automatically and added to your "account". Maggot Farm - Max's health bar will be automatically regenerated when visiting a Stronghold.Īrmory - replenishes ammunition whenever visiting a Stronghold (works on shotgun, knives, sniper rifle, Thunderpoon). Water storage - your canteen will be automatically refilled when visiting a Stronghold. Later you can use the quick travel to return there and replenish supplies. Important: Even if you are not interested in upgrading all the Strongholds, take some time and improve the projects that might interest you in at least one of them. ![]() Visual upgrade of the Stronghold is a "side effect" of constructing projects.
