Sodium-ion battery

The sodium-ion battery (NIB or SIB) is a type of rechargeable battery that uses sodium ions (Na+) as its charge carriers. Its working principle and cell construction are almost identical with those of lithium-ion battery (LIB) types, but replace lithium with sodium. SIBs received academic and commercial interest in the 2010s and 2020s, largely due to the uneven geographic distribution, high environmental impact and high cost of many of the materials required for lithium-ion batteries. Chief among these are lithium, cobalt, copper and nickel, which are not strictly required for many types of sodium-ion batteries.[1] The largest advantage of sodium-ion batteries is the natural abundance of sodium.[2] Challenges to adoption of SIBs include low energy density and insufficient charge-discharge cycles.[3]

As of 2022, sodium-ion batteries had not become commercially significant, but this might change as CATL, the world's biggest battery manufacturer, announced of starting mass production of SIBs in 2023. The technology is not mentioned in a United States Energy Information Administration report on battery storage technologies.[4] Furthermore, no electric vehicles use sodium-ion batteries. In February 2023, the Chinese HiNa Battery Technology Co., Ltd. placed a 120 Wh/kg sodium-ion battery in an electric test car for the first time. [5] Also in 2023 Energy storage manufactuer Pylontech obtained the first sodium-ion battery certificate by TÜV Rheinland. [6]


Sodium-ion battery development took place in the 1970s and early 1980s. However, by the 1990s, lithium-ion batteries had more demonstrated commercial promise, causing interest in sodium-ion batteries to decline.[7][8] In the early 2010s, sodium-ion batteries experienced a resurgence, driven largely by the increasing cost of lithium-ion battery raw materials.[7]

Operating principleEdit

SIB cells consist of a cathode based on a sodium containing material, an anode (not necessarily a sodium-based material) and a liquid electrolyte containing dissociated sodium salts in polar protic or aprotic solvents. During charging, sodium ions move from the cathode to the anode while electrons travel through the external circuit. During discharge, the reverse process occurs.


Due to the physical and electrochemical properties of sodium, SIBs require other materials than those used for LIBs.[9]


SIBs use hard carbon, a disordered carbon material consisting of a non-graphitizable, non-crystalline and amorphous carbon. Hard carbon's ability to absorb sodium was discovered in 2000.[10] This anode was shown to deliver 300 mAh/g with a sloping potential profile above ⁓0.15 V vs Na/Na+. It accounts for roughly half of the capacity and a flat potential profile (a potential plateau) below ⁓0.15 V vs Na/Na+. Graphite anodes for LIBs offer typical capacities of 300–360 mAh/g. The first sodium-ion cell using hard carbon was demonstrated in 2003 and showed a 3.7 V average voltage during discharge.[11] Hard carbon is preferred due to its excellent combination of capacity, (lower) working potentials and cycling stability.

In 2015 researchers demonstrated that graphite could co-intercalate sodium in ether-based electrolytes. Low capacities around 100 mAh/g were obtained with relatively high working potentials between 0 – 1.2 V vs Na/Na+.[12] Some sodium titanate phases such as Na2Ti3O7,[13][14][15] or NaTiO2,[16] delivered capacities around 90–180 mAh/g at low working potentials (< 1 V vs Na/Na+), though cycling stability was limited to a few hundred cycles. Numerous reports described anode materials storing sodium via alloy reaction and/or conversion reaction.[7] Alloying a sodium metal brings the benefits of regulating sodium-ion transport and shielding the accumulation of electric field at the tip of sodium dendrites.[17] Wang, et al. reported that a self-regulating alloy interface of nickel antimony (NiSb) was chemically deposited on a Na metal during discharge. This thin layer of NiSb regulates the uniform electrochemical plating of Na metal, lowering overpotential and offering dendrite-free plating/stripping of Na metal over 100 h at a high areal capacity of 10 mAh cm−2.[18]

In another study, Li et al. prepared sodium and metallic tin Na
/Na through a spontaneous reaction.[19] This anode could operate at a high temperature of 90 °C (194 °F) in a carbonate electrolyte at 1 mA cm−2 with 1 mA h cm−2 and the full cell exhibited a steady cycling rate of 100 cycles at a current density of 2C.[19] Despite sodium alloy's ability to operate at extreme temperatures and regulate dendritic growth, the severe stress-strain experienced on the material in the course of repeated storage cycles limits cycling stability, especially in large-format cells. Researchers from Tokyo University of Science achieved 478 mAh/g with nano‐sized magnesium particles, announced in December 2020.[20]

In 2021 researchers from China tried layered structure MoS
as a new type of anode for sodium-ion batteries. A dissolution-recrystallization process densely assembled carbon layer-coated MoS2 nanosheets onto the surface of polyimide-derived N-doped carbon nanotubes. This kind of C-MoS2/NCNTs anode can store 348 mAh/g at 2 A/g, with a cycling stability of 82% capacity after 400 cycles at 1 A/g.[21] TiS2 is another potential material for SIBs because of its layered structure, but has yet to overcome the problem of capacity fade, since TiS2 suffers from poor electrochemical kinetics and relatively weak structural stability. In 2021 researchers from Ningbo, China employed pre-potassiated TiS2, presenting rate capability of 165.9mAh/g and a cycling stability of 85.3% capacity after 500 cycles.[22]

Graphene Janus particles have been used in experimental sodium-ion batteries to increase energy density. One side provides interaction sites while the other provides inter-layer separation. Energy density reached 337 mAh/g.[23]


Sodium-ion cathodes store sodium via intercalation. Owing to their high tap density, high operating potentials and high capacities, cathodes based on sodium transition metal oxides have received the greatest attention. To keep costs low, research attempts to minimize costly elements such as Co, Cr, Ni or V. A P2-type Na2/3Fe1/2Mn1/2O2 oxide from earth-abundant Fe and Mn resources can reversibly store 190 mAh/g at average discharge voltage of 2.75 V vs Na/Na+ utilising the Fe3+/4+ redox couple – on par or better than commercial lithium-ion cathodes such as LiFePO4 or LiMn2O4.[24] However, its sodium deficient nature lowered energy density. Significant efforts were expended in developing Na-richer oxides. A mixed P3/P2/O3-type Na0.76Mn0.5Ni0.3Fe0.1Mg0.1O2 was demonstrated to deliver 140 mAh/g at an average discharge voltage of 3.2 V vs Na/Na+ in 2015.[25] In particular, the O3-type NaNi1/4Na1/6Mn2/12Ti4/12Sn1/12O2 oxide can deliver 160 mAh/g at average voltage of 3.22 V vs Na/Na+,[26] while a series of doped Ni-based oxides of the stoichiometry NaaNi(1−x−y−z)MnxMgyTizO2 can deliver 157 mAh/g in a sodium-ion “full cell” with a hard carbon anode at average discharge voltage of 3.2 V utilising the Ni2+/4+ redox couple.[27] Such performance in full cell configuration is better or on par with commercial lithium-ion systems. A Na0.67Mn1−xMgxO2 cathode material exhibited a discharge capacity of 175 mAh/g for Na0.67Mn0.95Mg0.05O2. This cathode contained only abundant elements.[28] Copper-substituted Na0.67Ni0.3−xCuxMn0.7O2 cathode materials showed a high reversible capacity with better capacity retention. In contrast to the copper-free Na0.67Ni0.3−xCuxMn0.7O2 electrode, the as-prepared Cu-substituted cathodes deliver better sodium storage. However, cathodes with Cu are more expensive.[29]

Research has also considered cathodes based on polyanions. Such cathodes offer lower tap density, lowering energy density on account of the bulky anion. This may be offset by the stronger covalent bonding of the polyanion that positively impacts cycle life and safety. Among polyanion-based cathodes, sodium vanadium phosphate[30] and fluorophosphate[31] have demonstrated excellent cycling stability and in the latter, an acceptably high capacity (⁓120 mAh/g) at high average discharge voltages (⁓3.6 V vs Na/Na+).[32]

Several reports discussed the use of various Prussian blue and Prussian blue analogues (PBAs), with the patented rhombohedral Na2MnFe(CN)6 displaying 150–160 mAh/g in capacity and a 3.4 V average discharge voltage[33][34][35] and rhombohedral Prussian white Na1.88(5)Fe[Fe(CN)6]·0.18(9)H2O displaying initial capacity of 158 mAh/g and retaining 90% capacity after 50 cycles.[36]


Sodium-ion batteries can use aqueous and non-aqueous electrolytes. The limited electrochemical stability window of water results in lower voltages and limited energy densities. Non-aqueous carbonate ester polar aprotic solvents extend the voltage range. These include ethylene carbonate, dimethyl carbonate, diethyl carbonate, and propylene carbonate. The most widely used non-aqueous electrolyte uses sodium hexafluorophosphate as the salt dissolved in a mixture of these solvents. Additionally, electrolyte additives can improve performance metrics.[citation needed]


Sodium-ion batteries have several advantages over competing battery technologies. Compared to lithium-ion batteries, sodium-ion batteries have somewhat lower cost, slightly lower energy density, better safety characteristics, and similar power delivery characteristics.

The table below compares how NIBs in general fare against the two established rechargeable battery technologies in the market currently: the lithium-ion battery and the rechargeable lead–acid battery.[27][37]
