Organic cathode materials have recently attracted abundant attention due to their flexible structural tunability and recyclability. However, the low intrinsic electrical conductivity and high solubility in electrolytes of organic electrode materials have significantly limited their practical application. Herein, we present [5,15-bis(ethynyl)-10,20-difurylporphinato] copper(II) (Cu-DEOP) as a new cathode for rechargeable organic lithium batteries (ROLBs). The combination of both ethynyl and furyl groups of the CuDEOP cathode with a nanorod structure renders it with enhanced structural stability and an extended delocalized πelectron system to deliver excellent cycling stability (capacity retention of 76% after 6000 cycles) and a high power density (16 kW kg −1 ). The furyl electroactive groups participate in charge storage contribution to achieve a reversible six-electron-transfer redox reaction in a specific voltage range. The mechanism characterizations indicate that the nitrogen atoms on the porphyrin ring act as active sites to alternatively store both PF 6 − anions and Li + cations, and the charge storage process is a pseudocapacitive-dominated reaction. This observation will offer a new avenue for designing functionalized molecules for electrochemical energy-storage (EES) systems.

“…Additionally, the storage of insoluble Li 2 CO 3 and the rapid diffusion of CO 2 molecules need sufficient space, otherwise, it will gradually block the tunnels and thus hinder the interaction between CO 2 and electrolyte. Since the CRR and CER exhibit electrocatalytic behavior and their efficiency deeply relies on electrocatalysts, 9,10 it is therefore quite imperative to construct a highly efficient and rational electrocatalyst. For example, carbon-based materials have been explored due to their high electrical conductivity and large surface area.…”

“…At present, the development of energy storage devices with a high energy density has received increasing attention due to constantly rising energy demands. , Since their creative commercialization in 1991, lithium-ion batteries (LIBs) have changed our way of life and provide energy for various equipment, such as portable electronics and electric vehicles. − However, the limited lithium resources and security issues have caused serious concern for the large-scale application of LIBs. , Therefore, great efforts have been made to develop a high-performance and safe next-generation energy storage system. Owing to the unique mechanism based on the simultaneous intercalation of cations and anions into the anode and cathode, respectively, during the charging process, dual-ion batteries (DIBs) could provide a high working voltage and energy density. − Besides, DIBs show several typical characteristics of low cost and safety and are environmentally friendly and so have been considered promising energy storage devices. − …”

Energy issues have attracted great concern worldwide. Developing new energy has been the main choice, and the exploitation of the electrochemical energy storage devices plays an important role. Herein, a high-performance dual-ion battery system is proposed, which consists of a graphite cathode and SnS 2 anode, with a high-concentration lithium salt electrolyte (4 M LiTFSI). The benefits from the typical sandwich-like layer structure of SnS 2 are as follows: the highest discharge specific capacity of the battery could reach 130.0 mA h g −1 at a current density of 100 mA g −1 , and even under an ultra-high current density of 2000 mA g −1 , the highest capacity of 66.3 mA h g −1 is still achieved, with an outstanding capacity retention over 100% after 1000 cycles. Inspiringly, this system delivers an excellent low self-discharge of 1.19%/h, surpassing most of the reported dual-ion batteries. In addition, the working mechanism and structural stability are also investigated by X-ray diffraction and Raman spectra, indicating a good reversibility. These results reveal that this graphite/SnS 2 dualion battery system could provide a promising alternative for a future high-performance energy storage device.
