Lithium ion batteries have been considered as the most effective and practical technologies for electrochemical energy storage. To meet the demand for lithium ion batteries with high energy density and excellent cycle performance, numerous efforts have been devoted to the development of new electrode materials. Electrochemically active metal oxides have emerged as the most promising candidates for the anode materials in the next generation lithium ion batteries duo to their high theoretical capacities and natural abundance. However, the extremely high volume change induced by the alloying reaction with lithium in the bottleneck for the commercialization of these materials. To overcome these obstacles, carbonaceous materials are commonly introduced as matrices to absorb the volume changes and improve the structural stability of the electrode materials. Hence, the present article describes the synthetic pathway of carbon-coated nanomaterials and applications.

With the advancements in portable electronics and electric vehicle (EV) applications, the demand for lithium-ion batteries (LIBs) with high energy densities is ever increasing. Battery-powered transportation is being adopted more frequently due to its potential to enable a more sustainable society by reducing vehicle emissions from fossil fuels. There has been exponential growth in the need for high-capacity LIBs in all types of EVs, including hybrid and full electric automobiles, e-bikes, and drones, as well as electric tools, cell phones, tablets, and, more recently, house storage; this growth significantly increases the consumption of source material commodities,especially cobalt. Despite its drop in price in the last couple of years due to increased mining, cobalt remains expensive, and its price increase has gained momentum again compared toother electrode materials due to higher demand. Moreover, its toxicity and difficult mining practices could result in many problems, including excessive carbon dioxide and nitrogendioxide emission along with a possible much higher demand in the long term. This provides a strong motivation to explore alternatives to battery source materials. In this article, we present a selection of our important works on LIBs, with a focus on alternative electrode chemistries by using abundant and sustainable material sources. As alternatives to traditional graphite-based anodes, we demonstrate the successful use of both silicon electrodes derived from beach sand and waste glass and carbon electrodes derived from portobello mushroom and waste plastic precursors. In addition, we demonstrate stable cycling of batteries with nonconventional electrode chemistries, such as lithium-sulfur with TiO2-coated sulfur electrodes and sulfur-silicon full cell batteries with integrated lithium sources. Batteries prepared by sustainable methods not only perform better than conventional ones but also result in reduced costs. Since accurate determination of battery state of health is another important challenge, we further present our electrochemical impedance spectroscopy-based analysis of LIBs, which could potentially be utilized in safety evaluations of current and next-generation LIBs.

In this study we prepared potassium-ion batteries (KIBs) displaying high output voltage and, in turn, a high energy density, as replacements for lithium-ion batteries (LIBs). Organic electrode materials featuring void spaces and flexible structures can facilitate the mobility of K+ to enhance the performance of KIBs. We synthesized potassium maleamate (K-MA) from maleamic acid (MA) and applied as an anode material for KIBs and LIBs, with 1 M potassium bis(fluorosulfonyl)imide (KFSI) and 1 M lithium bis(fluorosulfonyl)imide (LiFSI) in a mixture of ethylene carbonate and ethyl methyl carbonate (1:2, v/v) as respective electrolytes. The K-MA_KFSI anode underwent charging/discharging with carbonyl groups at low voltage, due to the K···O bond interaction weaker than Li···O. The K-MA_KFSI and K-MA_LiFSI anode materials delivered a capacity of 172 and 485 mA h g−1 after 200 cycles at 0.1C rate, respectively. K-MA was capable of accepting one K+ in KIB, whereas it could accept two Li+ in a LIB. The superior recoveries performance of K-MA_LiFSI, K-MA_KFSI, and Super P_KFSI at rate of 0.1C were 320, 201, and 105 mA h g−1, respectively. This implies the larger size of K+ can reversibly cycling at high rate.

Abstract High-energy density lithium ion batteries (LIBs) rely heavily on innovations of electrode materials. Herein, the porous TiNb2O7/carbon nanofibers (TNO/CNFs) have been prepared through the hydrothermal method and electrostatic spinning method as the anode for the Li-ion battery. The structure of porous TNO/CNFs after annealing at 700 °C for 2 h is intact, and lots of holes are found on that surface of nanofibers. Porous TNO/CNFs as the anode show better electrochemical performance than TNO/CNFs, the capacity retention of porous TNO/CNFs is 81.6% (147 mA h/g) with an exceptionally high rate (at 20 C rate). And the capacity retention of porous TNO/CNFs is higher than ≈77% that of TNO/CNFs (112 mA h/g). The superior electrochemical performance of these porous TNO/CNFs can be attributed to the unique porous carbon nanofiber structure: this structure of porous nanofibers not only provides a larger effective area for contact with the electrolyte but also reduces the rate-limiting Li diffusion path, leading to faster charge transfer.

Positive Electrode Materials

Lithium ion batteries (LIBs) are one of the most promising secondary batteries due to their advantages including long cycle life, high energy density, limited self-discharge, high operating voltage and environmental friendliness. The development of electrode materials is crucial for the further application of LIBs. There are many effective ways to enhance the performance of positive electrode materials of LIBs such as surface coating, ion doping, preparation of composite materials and nanosized materials and so forth. Among them, surface coating is considered to be a promising way to improve the electrochemical performance of LIBs. Surface coating can normally form a physical barrier or a doped surface layer to play favorable roles for the electrode materials, such as hindering side reactions between positive electrode materials and the electrolyte. In this paper, different kinds of surface coating layers will be discussed according to previous research, including carbon materials, metal oxides, metal fluorides, metal phosphates, nonmetal oxides, electrode materials coating layer, hybrid coating layer, polymer and so forth. In addition, the mechanism of these coating materials will be summarized, and the future development will be discussed in this paper.
