Abstract High energy density lithium-ion batteries are urgently needed due to the rapid growth demands of electric vehicles, electronic devices, and grid energy storage devices. There is still significant opportunity to improve the energy density of existing state-of-the-art lithium-ion batteries by optimizing the separator thickness, which is usually ignored. Here, the dependence of battery gravimetric and volumetric energy densities on separator thickness has been quantitatively discussed in different type Li-ion batteries by calculations combined with experiments. With a decrease in separator thickness, the volumetric energy density is greatly improved. Meanwhile, the gravimetric energy densities are significantly improved as the electrolyte soaking in the separator is reduced. The gravimetric and volumetric energy densities of graphite (Gr) | NCM523 cells enable to increase 11.5% and 29.7%, respectively, by reducing the thickness of separator from 25 μm to 7 μm. Furthermore, the Li | S battery exhibits an extremely high energy density of 664.2 Wh Kg-1 when the thickness of the separator is reduced to 1 μm. This work sheds fresh light on the rational design of high energy density lithium-ion batteries.

All-solid-state Li batteries (ASSLiBs) that use solid-state electrolytes (SSEs) to replace liquid organic electrolytes are considered as promising next-generation energy storage devices because of their wide electrochemical potential windows, high safety, and high energy density. Therefore, ASSLiBs have attracted a lot of attention in recent years. In this review, we focus on the main challenges on the synthesis and the electrochemical properties of the SSEs including (i) crystal structures and modification of kinetics of Li-ion migration through doping technology, (ii) synthesis technologies and its effect on the electrochemical performances of the SSEs, and (iii) ambient condition stability and degration of SSEs. Finally, perspectives of future researches on the SSEs are presented.

The Cost

Lithium-ion capacitors (LICs) are considered to be one of the most promising energy storage devices which have the potential of integrating high energy of lithium-ion batteries and high power and long cycling life of supercapacitors into one system. However, the current LICs could only provide high power density at the cost of low energy density due to the sluggish Li+ diffusion and/or low electrical conductivity of the anode materials. Moreover, the serious capacity and kinetics imbalances between anode and cathode result in not only inferior rate performance but also unsatisfactory cycling stability. Therefore, designing high-power and structure stable anode materials is of great significance for practical LICs. Under this circumstance, graphene-based materials have been intensively explored as anodes in LICs due to their unique structure and outstanding electrochemical properties and attractive achievements have been made. In this review, the recent progresses of graphene-based anode materials for LICs are systematically summarized. Their synthesis procedure, structure and electrochemical performance are discussed with a special focus on the role of graphene. Finally, the outlook and remaining challenges are presented with some constructive guidelines for future research.

Abstract Among various energy-storage devices, electrochemical capacitors (ECs) are prominent power provision but show relatively low energy density. One way to increase the energy density of ECs is to move from carbon-based electric double-layer capacitors to pseudocapacitors, which manifest much higher capacitance. However, compared with carbon materials, the pseudocapacitive electrodes suffer from high resistance for electron and/or ion transfer, significantly restricting their capacity, rate capability and cyclability. Rational design of electrode materials offers opportunities to optimize their electrochemical performance, leading to devices with high energy density while maintaining high power density. This paper reviews the different approaches of electrodes striving to advance the energy and power density of ECs.
