Research progress of electrolyte additives for subzero-temperature aqueous sodium-ion batteries
Open accessAbstract
Sodium-ion batteries are considered one of the perspective alternatives to lithium-ion batteries due to their affordability and plentiful supply of sodium. However, traditional sodium-ion batteries that use organic electrolytes pose a threat to public safety and the ecological environment. As a result, aqueous electrolytes with high safety and cost-effectiveness are becoming more popular. Unfortunately, typically aqueous electrolytes face limitations in ionic conductivity and have relatively high freezing points, which hinder their ability to function at extremely low temperatures. These issues can be resolved with an easy-to-use method called electrolyte additive. The research on electrolyte additives for subzero-temperature aqueous sodium-ion batteries has not been systematically reviewed at present. This review aims to provide a comprehensive summary of the electrolyte additives for subzero-temperature aqueous sodium-ion batteries. Furthermore, the potential development paths of electrolyte additives to promote the advancement of electrochemical energy storage are also explored. Graphical Abstract

These properties make NVP especially promising for low-temperature applications, as sluggish ion transport and interfacial charge transfer typically limit performance under such conditions.
“These properties make NVP especially promising for low-temperature applications, as sluggish ion transport and interfacial charge transfer typically limit performance under such conditions14,15,16.”
From High-performance Na3V2(PO4)3/C cathode for efficient low-temperature lithium-ion batteries (2025) · cites this paper as [15]
The Introduction (page unavailable) says low temperatures slow ion movement and reduce charge-transfer efficiency. Section 3.1 (page unavailable) reports NVP/NTP cells operating from −50 °C to 50 °C, but attributes that range to electrolyte additives, not to properties of NVP itself. The source therefore supports the low-temperature challenge and an example of NVP use, but not the stated reason NVP is especially promising. (LLM, conf=0.84)
Experimental — accuracy not yet measuredNa3V2(PO4)3 (NVP) has a NASICON-type structure, which provides 3D channels for fast Na-ion diffusion and high structural stability.
“Among various sodium-based cathodes, Na3V2(PO4)3 (NVP) has garnered significant attention due to its NASICON-type structure, which provides 3D channels for fast Na-ion diffusion and high structural stability.”
From High-performance Na3V2(PO4)3/C cathode for efficient low-temperature lithium-ion batteries (2025) · cites this paper as [15]
Section 2 (page unavailable) mentions Na3V2(PO4)3 as an anode in a hybrid battery, and Section 3.1 discusses the stability of an NVP/NTP battery with electrolyte additives. Neither passage addresses NVP’s NASICON structure, three-dimensional Na-ion diffusion channels, or intrinsic structural stability; searches for those terms found no supporting passage.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
