It would be unwise to assume ‘conventional’ lithium-ion batteries are approaching the end of their era and so we discuss current strategies to improve the current and next generation systems, where a holistic approach will be needed to unlock higher energy density while also maintaining lifetime and safety. We end by briefly reviewing areas where fundamental science advances will be needed to enable revolutionary new battery systems.

CaCoO/rGO was prepared by combining a sol-gel strategy and mechanical ball milling method. The Rietveld refinement results demonstrated a single-phase structure with a monoclinic symmetry. When utilized as an anode for lithium-ion batteries, it exhibited excellent rate performance and electrochemical stability due to the significantly decreasing particle size as well as the formation of a conductive rGO network in the composite after ball milling.

Spinel lithium manganese oxide (LiMnO, LMO) is a promising cathode material with nontoxicity, high operating voltage, and low cost. However, structural collapse during battery cycling ─ caused by Mn dissolution and the Jahn-Teller effect ─ is a critical disadvantage, reducing cycle retention, particularly at high temperatures. In this study, to solve these critical issues, we introduce Cu(HITP) (CuHITP; HITP = 2,3,6,7,10,11-hexaiminotriphenylene), a conductive two-dimensional (2D) metal-organic framework (MOF) as a surface coating material.

Amid the burgeoning demand for electrochemical energy storage and neuromorphic computing, fast ion transport behavior has attracted widespread attention at both fundamental and practical levels. Here, based on the nanoconfined channel of graphene oxide laminar membranes (GOLMs), the lithium ionic conductivity typically exceeding 10 mS cm is realized, one to three orders of magnitude higher than traditional liquid or solid lithium-ion electrolyte. Specifically, the nanoconfined lithium hexafluorophosphate (LiPF)-ethylene carbonate (EC)/ dimethyl carbonate (DMC) electrolyte demonstrates the ionic conductivity of 170 mS cm, outperforming the bulk counterpart by ≈16 fold.

Does light or heat play a seminal role in photo-rechargeable batteries? This study unravels the effects of light in the exciton formation and separation processes in a photocathode, leading to the charging or de-intercalation of Li ions in a lithium-ion battery. Light induced oxidation of Ti to Ti in the Li(TiS-TiO) heterostructure cathode is shown here, while heating does not elicit such changes. With the aid of photogenerated electrons at the cathode, the de-lithiated Li ions from Li(TiS-TiO) get intercalated in the graphite anode during the photocharging process.

In this research work, four distinct WO electrodes were synthesized and coated with three different polymers, known as polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) in poly(4-styrenesulfonate) (PEDOT:PSS) and polyaniline (PANi), using electropolymerization techniques. The morphological features of the samples were thoroughly characterized through Field Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM) analyses. Additionally, contact angle measurements and electrochemical characterizations were used to verify the performance of each electrode, aiding in the prediction of their suitability for energy storage applications in lithium-ion batteries.
