“…Figure 4 illustrates the CV profile of the CNT@Mn 3 O 4 electrode, depicting the current variation as a function of applied potential within the voltage range of 0.01 to 3.0 V vs. Li/Li + at a scan rate of 10 mV s −1 . A broad cathodic peak at ~1.3 V was observed in the first stage due to the reduction of Mn 3+ to Mn 2+ [18,19]. The cathodic peaks observed at 0.02 V during the first scan were attributed to the process of inserting Li + into the CNT framework.…”

A composite electrode of carbon nanotube CNT@Mn3O4 nanocable was successfully synthesized via direct electrophoretic deposition onto a copper foil, followed by calcination. By uniformly depositing Mn3O4 nanoparticles on CNTs, a nanocable structure of CNT@Mn3O4 can be formed, where the CNT acts as a “highway” for electrons and ions to facilitate fast transportation. Moreover, capacitive energy storage processes play a crucial role in lithium (Li) storage, especially during high scan rates. The significant contribution of capacitance is highly advantageous for the rapid transfer of Li+ ions, which ultimately results in an improved reversible capacity and prolonged cycle stability of the battery. A high specific capacity of 1367 mAh g−1 was maintained over 300 charge–discharge cycles at a current density of 1 A g−1, indicating excellent capacity retention and an extended cycle life. Furthermore, the synthesis process was facile and cost-effective, obviating the need for complex procedures such as mixing and pasting. Additionally, no binder was required, thereby enhancing battery quality efficiency.

Carbonaceous mesophase (CM) is an important precursor of carbon materials. Its structure, preparation conditions, and post-treatment conditions determine the structure and properties of carbon mesophase materials. However, conventional methods for the preparation of CMs are complex and require high temperatures above 400 °C. In this paper, a low-temperature solvothermal (LTS) method for obtaining CMs with high-temperature coal tar as the raw material and ethanol as the solvent is presented. With the LTS method, the required temperature is reduced from 410 to 230 °C, and the process of preparing pitch by tar rectification is simplified. This method thus provides a low-energy and environmentally friendly alternative to conventional CM synthesis methods. The resulting CMs by the LTC method exhibit impressive adsorption and electrochemical properties, making them highly suitable for a wide range of applications. After activation, the CMs exhibit a significant specific surface area of 1049.336 m2/g. Additionally, they possess mesopores with an average size of 3.620 nm, which enables them to effectively adsorb and remove up to 98.25% of methylene blue. The theoretical maximum adsorption capacity of the CMs for methylene blue is 364.71 mg/g. Additionally, the activated CMs demonstrate excellent electrochemical properties. The cyclic stability of the material was evaluated, and the specific capacitance retention rate was 96.69% after 2000 cycles. These findings highlight the potential of this low-temperature solvent thermal method for synthesizing high-performance CMs and their potential use in adsorption and electrochemical applications.
