“…Alternatively, ex situ coated mechanically stable artificial layers, such as polymer or solid‐state blocking layers, have been proposed to block the dendrite penetration. These interfacial layers stabilize the interface of the lithium anode with the liquid electrolytes, leading to improved Coulombic efficiency and safety.…”

Lithium-sulfur (Li-S) batteries have attracted tremendous interest because of their high theoretical energy density and cost effectiveness. The target of Li-S battery research is to produce batteries with a high useful energy density that at least outperforms state-of-the-art lithium-ion batteries. However, due to an intrinsic gap between fundamental research and practical applications, the outstanding electrochemical results obtained in most Li-S battery studies indeed correspond to low useful energy densities and are not really suitable for practical requirements. The Li-S battery is a complex device and its useful energy density is determined by a number of design parameters, most of which are often ignored, leading to the failure to meet commercial requirements. The purpose of this review is to discuss how to pave the way for reliable Li-S batteries. First, the current research status of Li-S batteries is briefly reviewed based on statistical information obtained from literature. This includes an analysis of how the various parameters influence the useful energy density and a summary of existing problems in the current Li-S battery research. Possible solutions and some concerns regarding the construction of reliable Li-S batteries are comprehensively discussed. Finally, insights are offered on the future directions and prospects in Li-S battery field.

“…It has been shown that both the separation of surface lithium fl akes and the continuous growth of an unstable solid electrolyte interphase layer (SEI) lead to reduction in capacity during cycling.

gas. At the same time, the penetration of renewable energy sources has opened up the possibility of creating a CO 2 -neutral mobility system, where electric vehicles are powered by wind, hydro, and solar energy.Broad fi nancial efforts are being made at a governmental and industrial level to fund research into new areas of energy storage. The U.S. Department of Energy has allocated $20 million to energy storage research in 2012 and $15 million the following year, while the German government has committed itself to ¤200 million between 2011 and 2018; [ 1 ] similar schemes are also being promoted in Japan by the New Energy and Industrial Technology Development Organization (NEDO). The EU-backed "Horizon 2020" program aims at funding research into energy storage technologies, a fi eld where the European Union lags behind the U.S. and East Asia. [ 2 ] Lithium-ion technology has established itself as a type of reliable energy-storage chemistry over the past 20 years, fi rst being used in camcorders, then mobile phones, laptops, and more recently electric cars. However, as the size of the battery pack increases, so does the belief that the cost per kW h and its energy density are not suitable for practical vehicle applications. The Tesla Model S, which sports a 400 km driving range, does so with a whopping 85 kW h battery pack that alone has up to twice the price of a standard economy car. With a current cost higher than 400 $ kW h −1 , electric cars have so far only entered a niche, high-end market where users are willing to pay a premium. Resizing the battery pack, and so the total cost of an electric car, results in a limited driving range (typically 100-150 km) that automatically restricts the use for long-haul journeys and triggers the so-called "range anxiety" feeling. For these reasons, the need to develop energy-storage technologies that enable at least a 500 km driving range, while retaining the same battery pack volume at an affordable price, is of primary interest for governments and car manufacturers. A Brief History of Lithium/Air BatteriesOver the years, the scientifi c community has focused its interest on advanced lithium-ion and fuel cells with only incremental improvements being made. Lithium-ion technology in particular is predicted to reach an asymptotic limit in specifi c Lithium/air is a fascinating energy storage system. The effective exploitation of air as a battery electrode has been the long-time dream of the battery community. Air is, in principle, a no-cost material characterized by a very high specifi c capacity value. In the particular case of the lithium/air system, energy levels approaching that of gasoline have been postulated. It is then not surprising that, in the course of the last decade, great attention has been devoted to this battery by various top academic and industrial laboratories worldwide. This intense investigation, however, has soon highlighted a series of issues that prevent a rapid development of the Li/air electrochemical system. Although several breakthroughs have be...

“…To solve these defects, some conductive polymers and fast ionic conductor materials were widely used as surface coating layer on the cathode active materials. [24][25][26][27][28][29][30] materials is coated with various amount of LBO glass via a simple wet chemical process followed by heat-treatment. As expected, the LBO coated materials exhibit obvious improvement both in electrochemical performances and thermal stability under high voltage.…”
