The demand for electrochemical energy storage is increasing rapidly due to a combination of decreasing costs in renewable electricity, governmental policies promoting electrification, and a desire by the public to decrease CO emissions. Lithium-ion batteries are the leading form of electrochemical energy storage for electric vehicles and the electrical grid. Lithium-ion cell anodes are mostly made of graphite, which is derived from geographically constrained, non-renewable resources using energy-intensive and highly polluting processes. Thus, there is a desire to innovate technologies that utilize abundant, affordable, and renewable carbonaceous materials for the sustainable production of graphite anodes under relatively mild process conditions. This review highlights novel attempts to realize the aforementioned benefits through innovative technologies that convert biocarbon resources, including lignocellulose, into high quality graphite for use in lithium-ion anodes.

Phosphorus is considered an ideal anode material for lithium ion storage by virtue of its high theoretical capacity and moderate lithiation potential. However, issues such as large volume expansion of phosphorus leading to an electrical loss of contact and instability of the solid electrolyte interface hinder its practical performance. Improvement strategies that can effectively suppress volume expansion and provide stable electrical contacts are urgently needed.

Ion encapsulation by solvent molecules significantly impacts ion transport and the adsorption mechanism in energy storage devices. The aim of this investigation is to analyse the adsorption mechanisms associated with the solvation shell of lithium ions near the electrode/electrolyte interface during the charging process. Simulations using molecular dynamics (MD) are conducted for LiPF salt in PC solvent confined in between two flat carbon electrodes.

To promote sustainable development and reduce fossil fuel consumption, there is a growing demand for high-performance, cost-effective, safe and environmentally friendly batteries for large-scale energy storage systems. Among the emerging technologies, zinc-air batteries (ZABs) have attracted significant interest. By integrating the principles of traditional zinc-ion batteries and fuel cells, ZABs offer remarkably high theoretical energy density at lower production cost compared to the current state-of-the-art lithium-ion batteries (LIBs).

Lithium-rich manganese oxide (LRMO) is a promising high-energy-density material for high-voltage lithium-ion batteries, but its performance is hindered by interfacial side reactions, transition metal dissolution, and oxygen release. To address these issues, we propose a high-voltage electrolyte strategy that utilizes cosolvent and additive synergy to create stable dual interphases at both the cathode and anode. Specifically, lithium difluoro(oxalato)borate (LiDFOB) additive sacrificially decomposes to form a uniform yet stable cathode-electrolyte interphase (CEI) layer, while cosolvent of bis(2,2,2-trifluoroethyl) carbonate (BTFEC) effectively adjusts the solvation structure and synergistically stabilizes the solid-electrolyte interphase (SEI) on the anode, ultimately achieving ultrahigh cycle stability and fast-charging feasibility.
