Lithium-ion batteries have aided the portable electronics revolution for nearly three decades. They are now enabling vehicle electrification and beginning to enter the utility industry. The emergence and dominance of lithium-ion batteries are due to their higher energy density compared to other rechargeable battery systems, enabled by the design and development of high-energy density electrode materials. Basic science research, involving solid-state chemistry and physics, has been at the center of this endeavor, particularly during the 1970s and 1980s. With the award of the 2019 Nobel Prize in Chemistry to the development of lithium-ion batteries, it is enlightening to look back at the evolution of the cathode chemistry that made the modern lithium-ion technology feasible. This review article provides a reflection on how fundamental studies have facilitated the discovery, optimization, and rational design of three major categories of oxide cathodes for lithium-ion batteries, and a personal perspective on the future of this important area.

Transition metal oxides (TMOs) are a promising material for use as anodes in lithium-ion batteries (LIBs). TMO anode can be classified on the basis of their lithiation/delithiation mechanism, such as intercalation mechanism-based TMO anode, conversion mechanism-based TMOs, and alloying/dealloying mechanism-based TMO anode. Each class of TMOs has its own advantages and limitations.

The rapid increase of electronic waste, particularly battery waste, presents significant environmental challenges such as pollutant emissions and resource depletion, emphasizing the need for effective valorization and reuse strategies. This study introduces a novel approach for repurposing end-of-life lithium iron phosphate (LFP) batteries as catalysts in the pyrolysis of walnut shells (WS). Characterization analyses revealed that LFP provides both Lewis and Brønsted acid sites, which alter the thermal decomposition pathway of WS.

Aramid films are potential separator candidates for high-safety lithium-ion batteries (LIBs) due to their inherent flame retardancy and outstanding thermal stability. However, both weak liquid electrolyte wettability and poor mechanical properties of aramid separators for lithium-ion batteries result in low ionic conductivity and unsatisfactory electrochemical performance for LIBs. Herein, a novel asymmetric porous composite separator composed of a relatively dense nanocellulose (CNC) layer and a porous poly(m-phenylene isophthalamide) (PMIA) supporting layer has been fabricated by using a water-induced phase conversion process.

Solid-state lithium-ion batteries have raised considerable attention due to their great potential for the development of new energy storage devices with high energy density and safety. However, enhancing ion conductivity in solid-state electrolytes stands as a pivotal challenge for the large-scale commercialization of next-generation lithium-ion batteries. Here, a high-pressure strategy is reported to achieve the significant enhancement of lithium-ion conductivity by 2 orders of magnitude and the disappearance of grain boundary resistance in polyoxometalate LiPWO electrolyte via an irreversible phase transition from Keggin to bronze structure.
