“…Considering the high energy of LIBs, Li‐ion capacitors (LICs) have been the focus of research . For LICs, activated carbon (AC) is generally used as the capacitor‐type cathode material, and battery‐type insertion materials such as few‐layered graphene are extensively investigated as anodes, as summarized by Zhou and co‐workers . SICs with abundant Na sources have recently drawn more attention.…”

High-efficiency energy storage technologies and devices have received considerable attention due to their ever-increasing demand. Na-related energy storage systems, sodium ion batteries (SIBs) and sodium ion capacitors (SICs), are regarded as promising candidates for large-scale energy storage because of the abundant sources and low cost of sodium. In the last decade, many efforts, including structural and compositional optimization, effective modification of available materials, and design and exploration of new materials, have been made to promote the development of Na-related energy storage systems. In this Review, the latest developments of micro/nanostructured electrode materials for advanced SIBs and SICs, especially the rational design of unique composites with high thermodynamic stabilities and fast kinetics during charge/discharge, are summarized. In addition to the recent achievements, the remaining challenges with respect to fundamental investigations and commercialized applications are discussed in detail. Finally, the prospects of sodium-based energy storage systems are also described.

“…In hybrid energy storages, charges are asymmetrically stored by ion adsorption and pseudocapacitive interaction in cathode and anode materials, respectively, so that their charge and discharge processes can be controlled using different potential windows to increase energy density . Moreover, low‐cost hybrid energy storages can be developed using an earth‐abundant electrolyte including sodium (Na) ions . However, many electrode materials suffer from several obstacles such as safety and poor capacity in a sodium‐ion electrolyte.…”

Sodium‐ion energy storage is of the most attractive candidate for commercialization adoption due to the safety and cost demands of large‐scale energy storage systems, but its low energy density, slow charging capability, and poor cycle stability are yet to be overcome. Here, a strategy is reported to realize high‐performance sodium‐ion energy storage using battery‐type anode and capacitor‐type cathode materials. First, nitrogen‐doped mesoporous titanium dioxide (NMTiO2) structures are synthesized via the controlled pyrolysis of metal–organic frameworks. They exhibit interconnected open mesopores allowing fast ion transport and robust cycle stability with nearly 100% coulombic efficiency, along with rich redox‐reactive sites allowing high capacity even at a high rate of ≈90 C. Moreover, assembling the NMTiO2 anode with the nitrogen‐doped graphene (NG) cathode in an asymmetric full cell shows a high energy density exceeding its counterpart symmetric cell by more than threefold as well as robust cycle stability over 10 000 cycles. Additionally, it gives a high‐power density close to 26 000 W kg−1 outperforming that of a conventional sodium‐ion battery by several hundred fold, so that full cells can be charged within a few tens of seconds by the flexible photovoltaic charging and universal serial bus charging modules.

“…The outstanding synergy effect over six critical criteria for EESDs caused by the hybridization of two systems is clearly demonstrated in Figure . In some respects, therefore, LICs can be a more competent device than LIBs to meet the special needs of possessing both high energy density and power density, which considerably deserves great attention of scholars , , However, as mentioned above, the LIBs with the highest energy density, an acceptable power density and cycling life can also be specially applied in several unique fields which demand for high energy output in a stable way.…”

Spinel Li Ti O , known as a zero-strain material, is capable to be a competent anode material for promising applications in state-of-art electrochemical energy storage devices (EESDs). Compared with commercial graphite, spinel Li Ti O offers a high operating potential of ∼1.55 V vs Li/Li , negligible volume expansion during Li intercalation process and excellent thermal stability, leading to high safety and favorable cyclability. Despite the merits of Li Ti O been presented, there still remains the issue of Li Ti O suffering from poor electronic conductivity, manifesting disadvantageous rate performance. Typically, a material modification process of Li Ti O will be proposed to overcome such an issue. However, the previous reports have made few investigations and achievements to analyze the subsequent processes after a material modification process. In this review, we attempt to put considerable interest in complete device design and assembly process with its material structure design (or modification process), electrode structure design and device construction design. Moreover, we have systematically concluded a series of representative design schemes, which can be divided into three major categories involving: (1) nanostructures design, conductive material coating process and doping process on material level; (2) self-supporting or flexible electrode structure design on electrode level; (3) rational assembling of lithium ion full cell or lithium ion capacitor on device level. We believe that these rational designs can give an advanced performance for Li Ti O -based energy storage device and deliver a deep inspiration.
