Lithium–Sulfur Batteries: Progress and Prospects

Development of advanced energy‐storage systems for portable devices, electric vehicles, and grid storage must fulfill several requirements: low‐cost, long life, acceptable safety, high energy, high power, and environmental benignity. With these requirements, lithium–sulfur (Li–S) batteries promise g... Full description

description: Development of advanced energy‐storage systems for portable devices, electric vehicles, and grid storage must fulfill several requirements: low‐cost, long life, acceptable safety, high energy, high power, and environmental benignity. With these requirements, lithium–sulfur (Li–S) batteries promise great potential to be the next‐generation high‐energy system. However, the practicality of Li–S technology is hindered by technical obstacles, such as short shelf and cycle life and low sulfur content/loading, arising from the shuttling of polysulfide intermediates between the cathode and anode and the poor electronic conductivity of S and the discharge product LiS. Much progress has been made during the past five years to circumvent these problems by employing sulfur–carbon or sulfur–polymer composite cathodes, novel cell configurations, and lithium‐metal anode stabilization. This Progress Report highlights recent developments with special attention toward innovation in sulfur‐encapsulation techniques, development of novel materials, and cell‐component design. The scientific understanding and engineering concerns are discussed at the end in every developmental stage. The critical research directions needed and the remaining challenges to be addressed are summarized in the Conclusion. in lithium–sulfur (Li–S) batteries show great potential for maximizing the electrochemical utilization, electrode stability, cycle life, energy, and power. The development of sulfur‐encapsulated nanocomposites, porous cathodes, interlayers, surface‐coated separators, stabilized lithium‐metal anodes, and electrochemically active LiS cathode can enhance the scientific understanding of Li–S batteries and promote their commercialization.
