“…The applicability of three-electrode analytics extends beyond lithium-ion to lithium and sodium metal batteries, solid-state batteries. − Given the high specific capacity, sustainability, and low cost, Na–Sn batteries are promising next-generation batteries. However, Sn electrodes are plagued by large volume expansion, fractures, pulverization leading to a loss of active material and the electrochemical performance with cycling.…”

The performance and safety of lithium-ion batteries are plagued by several diverse, nonlinear aging mechanisms influenced by the electrochemical thermal interactions at the electrodes, usage history, and operating conditions. Understanding and deconvoluting the fundamental reaction mechanisms responsible for electrode degradation are key for developing technologies in Li-ion battery diagnostics and prognostics. Hence, there exists a need for high-precision operando techniques to investigate and characterize distinct electrode degradation modes over a gamut of operational variability. Cells embedded with a stable, nonpolarizable reference electrode offer an in situ and operando tool to decouple the complex electrochemical interplay between the electrode pair by measuring individual electrode responses simultaneously with the cell response in the time and frequency domains. This perspective comprehensively looks at 3-electrode (3ε) analytics as a versatile toolbox, highlighting recent techniques and parameters developed with an emphasis on degradation diagnostics and control strategies that is expected to drive the futuristic design of battery management systems.

Bimetallic Bi–Sn microspheres as high initial coulombic efficiency and long lifespan anodes for sodium-ion batteries

“…The emergence of sodium-ion batteries (SIBs) greatly mitigates the anxiety about the depletion of limited Li resources. − The similar cell structure, production process and operation principles make SIBs promising in the postlithium ion batteries (LIBs) era. To achieve high energy-density batteries, anode materials need to be high-capacity and low-voltage. − In this context, β-Sn comes in sight, , because of its high theoretical capacities (847 mAh g –1 ), low charge voltages (∼0.35 V vs Na + /Na), good electronic conductivity, and low toxicity. However, huge volume change (∼420%) during cycles remarkably lowers electrode stability, easily leading to particle pulverization, electronic disconnection and rapid degradation of electrochemical performance.…”

Microsized Gray Tin as a High-Rate and Long-Life Anode Material for Advanced Sodium-Ion Batteries

Sodium-ion batteries (SIBs) are developed to address the serious concern about the limited resources of lithium. To achieve high energy density, anode materials with a large specific capacity and a low operation voltage are highly desirable. Herein, microsized particles of gray Sn (α-Sn) are explored as an anode material of SIBs for the first time. The distinct structure of α-Sn endows it the reduced volume change, the improved interaction with polymer binders and the in situ formation of amorphous Sn, as supported by in situ XRD, TEM and DFT calculations. Therefore, α-Sn exhibits an excellent electrochemical performance, much better than β-Sn widely used before. Even microsized particles of α-Sn without any treatments deliver a capacity of ∼451 mAh g −1 after 3500 cycles at 2 A g −1 or ∼464 mAh g −1 at 4 A g −1 in a rate test. The results indicate the promising potential of α-Sn in SIBs.
