Special Issue Information

Dear Colleagues,

Tremendous progresses have been made on development of high-energy materials and electrode/electrolyte interphase optimization to enable a long-term cyclability performance of sustainable batteries. However, the deep understanding toward the interphase and structural-property relationship is still stating at the early stage as the limited research techniques and variable properties with time and dimension. Therefore, reliable regulation methods to tailoring the composition and property of high-energy materials and electrode/electrolyte interphase are necessary currently. Notably, the combination of high-throughput screening and advanced in-situ/ex-situ techniques would be beneficial to explore the electro-chemo-mechanical properties of the high-energy battery materials and design the electrode/electrolyte interphase.

The Research Topic seeks the latest research and development in electrode/electrolyte interphase and advanced materials for sustainable batteries. We encourage the submission of all types of articles, including Original Research, Perspective, Review and mini-Reviews on the following topics:

High-energy cathode/anode materials
Operando/in situ/ex situ characterization methods
Advanced electrolyte and additives
Solid-state batteries
Next generation batteries, such as Lithium metal batteries, Li-S batteries, Li-O₂ batteries,
Beyond Lithium battery, such as Na, Al Ca, Mg, and Zn batteries.
High-throughput screening of battery electrodes and electrolytes
Battery recycling and life-cycle analysis

Abstract

Single-crystal Ni-rich layered oxide materials LiNi_1−x−yCo_xMn_yO₂ (NCM, 1 – x − y ≥ 0.6) are emerging as promising cathode materials that do not show intergranular cracks as a result of the lack of grain boundaries and anisotropy of the bulk structure, enabling extended cyclability in lithium-ion batteries (LIBs) operating at high voltage. However, SC-NCM materials still suffer from capacity fading upon extended cycling. This degradation of capacity can be attributed to a reconstruction of the surface. A phase transformation from layered structures to disordered spinel/rock-salt structures was found to be responsible for impedance growth and capacity loss. Film-forming additives are a straightforward approach for the mitigation of surface reconstruction via the formation of a robust protection layer at the cathode’s surface. In this work, we investigate various additives on the electrochemical performance of single-crystal LiNi_0.83Co_0.11Mn_0.06O₂ (SC-NCM83). The results demonstrate that the use of 1% lithium difluoroxalate borate (LiDFOB) and 1% lithium difluorophosphate (LiPO₂F₂) additives substantially enhanced the cycling performance (with a capacity retention of 93.6% after 150 cycles) and rate capability in comparison to the baseline electrolyte (72.7%) as well as electrolytes using 1% LiDFOB (90.5%) or 1% LiPO₂F₂ (88.3%) individually. The superior cycling stability of the cell using the combination of both additives was attributed to the formation of a conformal cathode/electrolyte interface (CEI) layer, resulting in a stabilized bulk structure and decreased impedance upon long-term cycling, as evidenced via a combination of state-of-the-art analytical techniques.

Abstract

Three-dimensional (3D) printing, as an advanced additive manufacturing technique, is emerging as a promising material-processing approach in the electrical energy storage and conversion field, e.g., electrocatalysis, secondary batteries and supercapacitors. Compared to traditional manufacturing techniques, 3D printing allows for more the precise control of electrochemical energy storage behaviors in delicately printed structures and reasonably designed porosity. Through 3D printing, it is possible to deeply analyze charge migration and catalytic behavior in electrocatalysis, enhance the energy density, cycle stability and safety of battery components, and revolutionize the way we design high-performance supercapacitors. Over the past few years, a significant amount of work has been completed on 3D printing to explore various high-performance energy-related materials. Although impressive strides have been made, challenges still exist and need to be overcome in order to meet the ever-increasing demand. In this review, the recent research progress and applications of 3D-printed electrocatalysis materials, battery components and supercapacitors are systematically presented. Perspectives on the prospects for this exciting field are also proposed with applicable discussion and analysis. Full article
