Comparative Study of the Thermal Stability of Electrode Materials for Li-Ion and Na-Ion Batteries

Abstract

The thermal stability of the cathode and anode materials for Li-ion and Na-ion batteriesLiNi1/3Mn1/3Co1/3O2, LiFePO4, Li4Ti5O12, graphite, O3-NaNi1/3Fe1/3Mn1/3O2 (NFM), Na3V2(PO4)3 (NVP), β-NaVP2O7 (NVPO), Na3V2(PO4)2F3 (NVPF), and hard carbonwas studied by means of differential scanning calorimetry of the electrodes in the charged state and ex situ powder X-ray diffraction. The obtained results indicate that the thermal stability of the Na-ion cathode materials increases in the order NFM < NVPF < NVP < NVPO. The “heat on energy” term has been proposed and analyzed for all of the studied materials.

Thermal Behavior of Lithium- and Sodium-Ion Batteries: A Review on Heat Generation, Battery Degradation, Thermal Runway – Perspective and Future Directions

“…Less oxygen release would also help curtail the extent of combustion reactions between the products of other decomposition reactions during TR. Samigullian et al 50 studied the thermal stability of different cathode and anode materials for Li-ion and Na-ion batteries. Cathode materials studied for lithium-ion batteries included LiNi 1/3 Mn 1/3 Co 1/3 O 2 and LiFePO 4 , and anode materials included Li 4 Ti 5 O 12 , and graphite; the cathode materials investigated for sodium ion were O3 type Na-Ni 1/3 Fe 1/3 Mn 1/3 O 2 (NFM), Na 3 V 2 (PO 4 ) 3 (NVP), β-NaVP 2 O 7 (NVPO), and Na 3 V 2 (PO 4 ) 2 F 3 (NVPF) and hard carbon (HC) anode.…”

“…These techniques have been employed widely by researchers for various applications in battery design and characterization. Samigullin et al used DSC to study the thermal stability of the electrode materials for LIBs and SIBs, Mukai and Inoue compared the thermal behavior of Na- or Li-intercalated hard carbon with DSC analysis, Gnanaraj et al . employed DSC to study the properties of the commonly used electrolyte/LiPF 6 solutions in mixture of organic carbonates, and Huang et al and Zhong et al studied the thermal stability of cathode materials for LIBs using TGA.…”

Nanosheet-Assembled Hierarchical Petal-like Na4MnV(PO4)3@Carbonized-Polyaniline Microspheres for Stable Sodium-Ion Batteries

“…For the world’s better transition to a green economy, it is particularly key to develop advanced energy storage and conversion systems. , Exploiting a rechargeable battery with long cycling life and high energy density is critical to the advances of novel energy storage systems (ESSs). , Despite the widespread use of lithium-ion batteries (LIBs) in various fields of electronic devices, their limited availability and cost prevented them from being applied in large-scale ESSs. − Naturally, high-performance sodium-ion batteries (SIBs) are suitable for development in alternative ESSs due to the lower cost, abundant resources, and similar physicochemical mechanism to LIBs. − Therefore, it is urgent to advance cathode electrodes with high-rate performance and stable lifespan, which largely dominate the SIB performance advancement. , …”

Safety Evaluation of a Sodium-Ion Cell: Assessment of Vent Gas Emissions under Thermal Runaway

“…Na-ion technology is not limited to the NVPF variant, and innovation will likely promote advanced key materials (active materials of electrodes, electrolytes) in search of better functional performances. Moreover, other parameters that are critical for safety assessment, like thermal and electrical stability of the cell, should be further investigated …”
