Recently, researchers Zhang Huamin, Li Xianfeng and associate researcher Zhang Hongzhang, researchers at the Institute of Energy Storage Technology of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, used metal lithium with "low Ksp anti-dissolution effect" to immobilize lithium polysulfide and "interfacial polymerization and film formation effect" , To prepare both high stability, high safety and high capacity of the electrolyte solution, and to achieve its lithium-sulfur battery device applications. Related research findings are published on Nano Energy as "LiNO3-free electrolyte for Li-S battery: A solvent of choice with low Ksp of polysulfide and low dendrite of lithium". The research was funded by National Natural Science Foundation of China, Ministry of Education iCentral Energy Materials Collaborative Innovation Center (IChEM), Chinese Academy of Sciences Youth Innovation Association and the Dalian Institute of Chemical Physics 100 project funding. ã€Graphic Guide】 Figure 1 lithium-sulfur battery without LiNO3 electrolyte containing low Ksp polysulfide and low dendritic lithium ion Figure 2 PS in a large number of electrolyte diffusion a) Add 1 ml of 1.0 M PS to the electrolyte; b) Add 2 ml of 0.1 M PS to the electrolyte. Experiments were conducted at room temperature and recorded with a digital camera. ã€research content】 Lithium-sulfur battery because of its high energy density and low cost, is currently one of the hot international research. Lithium polysulfide "drag effect" and lithium metal "interface instability" is the lithium-sulfur battery is facing a key challenge. All along, researchers use lithium nitrate additives to solve the above problems, but lithium nitrate, carbon black, elemental sulfur battery system there is a security risk. For the first time, the team designed a high-performance lithium-ion-free electrolyte that combines lower lithium polysulfide solubility (Ksp), higher lithium ion conductivity, higher utilization of elemental sulfur, and superior metals Lithium interface stability. The 4000 mAh lithium-sulfur battery cell assembled with this electrolyte has a specific power of up to 60 Wkg-1, a specific energy of up to 350 Whkg-1, and a stable cycle of more than 30 cycles. This technology is expected to enable continuous flight of solar unmanned aircraft 1 month. This work provides a new idea for the design and preparation of lithium-sulfur battery electrolyte materials. Firstly, compared to other colors, black is widely recognized as a popular color. No matter where black is used, today we will talk about our company's black Electric Bicycles. Whether it is mountain electric bicycles or City Electric Bicycles, black can reflect the calm, introverted, and mysterious temperament of cyclists. Our company's independently developed MC01, MC02, and LiXA Mountain Electric Bike Frames all use black as the main color tone. The Mountain Ebike itself is a preferred model for outdoor mountain cycling enthusiasts, and the black electric bike frame can better showcase the charm and unique temperament of outdoor cycling. Imagine what a cool and handsome thing it would be for you to ride a black electric power assisted bicycle and fly through the mountains. The urban Electric Bicycle series requires different riders to choose from due to the environmental conditions they ride. Some prefer low-key black, some prefer white, and some prefer highly personalized colors such as red, yellow, blue, purple, or more distinctive colors. In short, regardless of which color you prefer, we can customize your electric powered bicycle for you.
