From scientific and technological points of view, poly(vinylidene fluoride), PVDF, is one of the most exciting polymers due to its overall physicochemical characteristics. This polymer can crystalize into five crystalline phases and can be processed in the form of films, fibers, membranes, and specific microstructures, being the physical properties controllable over a wide range through appropriate chemical modifications. Moreover, PVDF-based materials are characterized by excellent chemical, mechanical, thermal, and radiation resistance, and for their outstanding electroactive properties, including high dielectric, piezoelectric, pyroelectric, and ferroelectric response, being the best among polymer systems and thus noteworthy for an increasing number of technologies. This review summarizes and critically discusses the latest advances in PVDF and its copolymers, composites, and blends, including their main characteristics and processability, together with their tailorability and implementation in areas including sensors, actuators, energy harvesting and storage devices, environmental membranes, microfluidic, tissue engineering, and antimicrobial applications. The main conclusions, challenges and future trends concerning materials and application areas are also presented.

Currently, the main drivers for developing Li‐ion batteries for efficient energy applications include energy density, cost, calendar life, and safety. The high energy/capacity anodes and cathodes needed for these applications are hindered by challenges like: (1) aging and degradation; (2) improved safety; (3) material costs, and (4) recyclability. The present review begins by summarising the progress made from early Li‐metal anode‐based batteries to current commercial Li‐ion batteries. Then discusses the recent progress made in studying and developing various types of novel materials for both anode and cathode electrodes, as well the various types of electrolytes and separator materials developed specifically for Li‐ion battery operation. Battery management, handling, and safety are also discussed at length. Also, as a consequence of the exponential growth in the production of Li‐ion batteries over the last 10 years, the review identifies the challenge of dealing with the ever‐increasing quantities of spent batteries. The review further identifies the economic value of metals like Co and Ni contained within the batteries and the extremely large numbers of batteries produced to date and the extremely large volumes that are expected to be manufactured in the next 10 years. Thus, highlighting the need to develop effective recycling strategies to reduce the levels of mining for raw materials and prevention of harmful products from entering the environment through landfill disposal.

“…As the most basic cathode material, LiMn 2 O 4 has the advantages of green environmental protection, low cost, and good safety performance [9][10][11][12]. However, due to the disproportionation and Jahn-Teller effect [13], Mn dissolves, which reduces the cycle performance of LiMn 2 O 4 and limits its large-scale production and application [14][15][16].…”

The structure of Mn3O4 with an octahedron structure was similar to that of LiMn2O4, and the lithium manganate prepared with it had good electrochemical performance. During the preparation of octahedron Mn3O4, the effects of the pH regulator, temperature, and reaction pH on its morphology, specific surface area, and other properties were studied in this paper. LiMn2O4 was prepared from Octahedron Mn3O4 obtained by using better technology. The effects of calcination time and temperature on the physicochemical and electrochemical properties of LiMn2O4 were studied. The research results indicated that the optimal synthesis conditions for Mn3O4 were as follows: ammonia water was used as a pH regulator and complexing agent, reaction pH was 8, reaction temperature was 80 °C, reaction time was 12 h, and oxygen flow rate was 3 L∙min−1. The LiMn2O4 synthesized had a good octahedron morphology when the calcination temperature was 800 °C and the calcination time was 10 h. The first discharge-specific capacity was 121.9 mAh∙g−1 at a current density of 0.2 C, the discharge-specific capacity was 114.1 mAh∙g−1 after 100 cycles, and the capacity retention rate was 93.6%. Therefore, the lithium manganate prepared by using octahedron manganous oxide had good electrochemical reversibility and a good application prospect.
