摘要 ：
In the past several decades, the research communities have witnessed the explosive development of lithium-ion batteries, largely based on the diverse landmark cathode materials, among which the application of manganese has been intensively considered due to the economic rationale and impressive properties. Lithium-manganese-based layered oxides (LMLOs) are one of the most promising cathode material families based on an overall theoretical evaluation covering the energy density, cost, eco-friendship, etc. Unfortunately, the Mn3+ cation introduces severe Jahn–Teller (J–T) effect, which profoundly distorts the localized lattice structure and reduces the electrochemical stability. This perspective presents the principal comprehensions of the J–T effect in LMLOs and offers an outline picture of material design to suppress it. We outline the history of material design and further assess available approaches to address the J–T effect. Finally, we tentatively propose promising design trends with eliminated J–T effect to revive this important cathode material family toward practical applications. © 2021 Elsevier Inc.

摘要 ：
Layered transition-metal oxides have attracted intensive interest for cathode materials of sodium-ion batteries. However, they are hindered by the limited capacity and inferior phase transition due to the gliding of transition-metal layers upon Na+ extraction and insertion in the cathode materials. Here, we report that the large-sized K+ is riveted in the prismatic Na+ sites of P2-Na0.612K0.056MnO2 to enable more thermodynamically favorable Na+ vacancies. The Mn-O bonds are reinforced to reduce phase transition during charge and discharge. 0.901 Na+ per formula are reversibly extracted and inserted, in which only the two-phase transition of P2 ↔ P'2 occurs at low voltages. It exhibits the highest specific capacity of 240.5 mAh g-1 and energy density of 654 Wh kg-1 based on the redox of Mn3+/Mn4+, and a capacity retention of 98.2% after 100 cycles. This investigation will shed lights on the tuneable chemical environments of transition-metal oxides for advanced cathode materials and promote the development of sodium-ion batteries.

摘要 ：
The scalable production of flexible integrated micro-supercapacitors (MSCs) with high performance and low cost is urgently required. Printing is a promising strategy to build MSCs with designable shapes. Here, one kind of cost-effective and universal conductive ink derived from the porous activated biochar has been introduced, which is used for the scalable fabrication of carbon-based planar MSCs on various flexible substrates by the simple fabrication process of screen printing and program-controlled writing methods. The MSCs using the screen printing method have exhibited a favorable areal capacitance of 116 mF cm(-2) and a high areal energy density of 9.26 mu W h cm(-2), and the integrated MSCs connected seven cells in series can also output a voltage of 5.6 V. In addition, the MSC arrays in this work have also been used for storing unstable external energy from a hand dynamo. This study provides significant guidance to construct metal-free integrated MSCs and facilitates the progress towards self-sustainable energy in the future.

摘要 ：
Sun, wind and tides have huge potential in providing us electricity in an environmental-friendly way. However, its intermittency and non-dispatchability are major reasons preventing full-scale adoption of renewable energy generation. Energy storage will enable this adoption by enabling a constant and high-quality electricity supply from these systems. But which storage technology should be considered is one of important issues. Nowadays, great effort has been focused on various kinds of batteries to store energy, lithium-related batteries, sodium-related batteries, zinc-related batteries, aluminum-related batteries and so on. Some cathodes can be used for these batteries, such as sulfur, oxygen, layered compounds. In addition, the construction of these batteries can be changed into flexible, flow or solid-state types. There are many challenges in electrode materials, electrolytes and construction of these batteries and research related to the battery systems for energy storage is extremely active. With the myriad of technologies and their associated technological challenges, we were motivated to assemble this 2020 battery technology roadmap.

摘要 ：
Aluminum-ion batteries (AIBs) are considered to be alternatives to meet the increasing demands for energy storage due to their high theoretical capacity, low cost, high safety, and the rich abundance of aluminum. Chalcogen materials (sulfur, selenium, and tellurium (SSTs)) with high theoretical capacities are deemed to be promising cathode materials in AIBs. However, the challenges including sluggish reaction kinetics and inferior cycling stability in Al-SSTs batteries still remain. In order to realize the advantages and overcome the drawbacks of SSTs electrodes, several strategies have been attempted. In this perspective, the approaches in terms of SSTs cathodes, electrolytes, separators, and Al metal anodes to improve the electrochemical performance of Al-SSTs batteries are summarized and elaborated. The electrochemistry of Al-SSTs batteries, involving different valence states of the electrochemical products is also presented and highlighted. The issues to be solved for practical applications are listed and possible future directions for the development of more reliable Al-SSTs batteries are discussed.

摘要 ：
Solid polymer electrolytes have been considered as the promising candidates to improve the safety and stability of high-energy lithium metal batteries. However, the practical applications of solid polymer electrolytes are still limited by the low ionic conductivity, poor interfacial contact with electrodes, narrow electrochemical window and weak mechanical strength. Here, a series of novel block copolymer electrolytes with three-dimensional networks are designed by cross-linked copolymerization of the polyethylene glycol soft segments and hexamethylene diisocyanate trimer hard segments. Their ionic migration performances and interface compatibilities with Li metal anode have been optimized delicately by tailoring the ratio of these functional units. The optimized block copolymer electrolyte has shown an amorphous crystalline structure, a high ionic conductivity of ~5.7 × 10−4 S cm−1, high lithium ion transference number (~0.49), wide electrochemical window up to ~4.65 V (vs. Li+/Li) and favorable mechanical strength at 55 °C. Furthermore, the enhanced interface compatibility can well support the normal operations of lithium metal batteries using both LiFePO4 and LiNi0.8Co0.15Al0.05O2 cathodes. This study not only paves a new way to develop solid polymer electrolyte with optimizing functional units, but also provides a polymer electrolyte design strategy for the application demand of lithium metal battery. © 2020 Science Press

摘要 ：
Potassium-ion batteries are among the most promising candidates to satisfy the large-scale energy storage systems due to their low-cost and abundant potassium sources. However, it is highly desired to seek suitable cathode materials with high capacity and voltage platform, long cycling stability and durability. Transitional metal layered oxides as the most important cathode materials have been widely investigated in lithium-ion batteries and sodium-ion batteries. Recently, transitional metal layered oxides for potassium-ion batteries have aroused huge attention owing to their special structures and potential in applications. Although most transitional metal layered oxides exhibit tolerable capacities, the relationship between structure and electrochemical performance needs further investigation in detail. Herein, the research status and development of transitional metal layered oxides for potassium-ion batteries are summarized in this review. To solve the existing problems of transitional metal layered oxides in potassium-ion batteries, the improvement of air stability and electrochemical performance are also thoroughly discussed. Based on the achievements in recent years, a prospect on the further development of transitional metal layered oxides for potassium-ion batteries is also provided. © 2020
