What is a Sodium Starting Battery?
A Sodium Starting Battery is a new-generation 12V automotive battery using Sodium-ion technology. It is designed as a replacement for traditional lead-acid batteries, offering lighter weight, longer lifespan, better high/low temperature performance, and higher safety.
How does a sodium-ion battery work
Sodium-ion starting batteries store and release electrical energy by moving sodium ion between positive and negative electrodes.
What is sodium ion battery made of?
The kep components of sodium-ion batteries include:
Positive Electrode: Poly-anioniccompounds (NFPP)
Negative Electrode: Hard carbon
Electrolyte: NaPF6
Separator: PP/PE
Shell: PC+ABS+AI
Tab: Aluminium
What is NFPP？
NFPP is an abbreviation for a positive electrode material for sodium ion batteries, which also represents a type of sodium ion battery technology that uses this material. NFPP material is a mixed phosphate structure: its molecule contains both PO4 (phosphate) and P2O7 (pyrophosphate) polyanion groups, which together build a three-dimensional interconnected NASICON-type framework.
NFPP's Advantage——Ultra-Long Cycle Life
After Ti-doping optimization, NFPP retained 97.2 mAh/g after 5,000 cycles at a 10C rate, while crystal volume change during charge and discharge was only 2.98%. Small volume change means the framework undergoes almost no deformation as sodium ions repeatedly leave and re-enter it—and that is the fundamental reason for long service life.
NFPP's Advantage——Thermal Stability,High Safety
NFPP has excellent structural stability, very small volume change during cycling. The strong covalent bonds in its PO4 and P2O7 framework tightly lock oxygen atoms in place, fundamentally suppressing oxygen release at high temperatures. Oxygen release is precisely the core mechanism behind thermal runaway and severe fire in layered oxide systems. Its electrolyte(NaPF6) is resistant to high temperatures, and its decomposition temperature is 50 ℃ higher than LFP(LiPF6).
The Value of NFPP in Automotive Applications——Super cranking performance
The improved NFPP of Aeson Power CCA rating up to 20~25X of the nominal capacity and PHCA up to 50X. Thus around 2-3X of a lead acid. It makes your vehicle start smoother and faster every time.
The Value of NFPP in Automotive Applications——Long Service Life
NFPP’s environmental advantages run throughout the entire battery life cycle. On the materials side, NFPP is composed entirely of non-toxic elements such as iron, sodium, and phosphorus, and its production does not involve environmentally risky heavy metals such as cobalt, nickel, or vanadium.
The Value of NFPP in Automotive Applications——Environmental Benefits
NFPP’s environmental advantages run throughout the entire battery life cycle. On the materials side, NFPP is composed entirely of non-toxic elements such as iron, sodium, and phosphorus, and its production does not involve environmentally risky heavy metals such as cobalt, nickel, or vanadium.
Why Did Aeson Power Choose NFPP?
Layered oxides pursue the limit of energy density, pool cycling, and low safety. Prussian blue pursues the limit of cost but the stability and safety of the process have not been resolved yet. While NFPP pursues the dual limit of reliability and sustainability, with broader scenario adaptability and more obvious overall advantages. The technological maturity is also higher.
The Value of NFPP in Automotive Applications--excellent low-temp. adaptability
NFPP’s low-temperature advantage comes from two sources. First, sodium ions bind more weakly to the electrolyte than lithium ions do, making desolvation easier at low temperatures. Second, NFPP’s open three-dimensional framework provides wide ion-transport channels, allowing sodium ions to continue moving relatively smoothly even when low temperatures increase electrolyte viscosity.

Why NFPP is the best choice for the next generation of start stop batteries?
NFPP has obvious comprehensive advantages and huge potential. It has obvious comprehensive advantages such as super cranking, super cycling, excellent low-temp. adaptability, safety & cost controllability compare to lead acid or LFP. It is the best choice for the next generation of start stop batteries.
Lead-acid battery RC value and sodium battery conversion(Why SIB can achieved the same RC with lower capacity?)
Lead-acid battery capacity is nominal according to C20 (i.e., 0.05C discharge to 10.5V up to 20hour can be), due to the lead-acid battery discharge capacity is sensitive of the discharge rate(i.e., the discharge rate increases, the capacity of the discharge decreased significantly, as the RC is equivalent to lead-acid in about 0.25C ~ 1.2C, is a medium to high rate of discharge, so the RC for the 33~ 100Ah batteries to say that about (60% ~ 80%) X C20.
Lead-acid and sodium batteries, which is more suitable for high-power use?
In terms of performance, sodium batteries have superior high rate performance, so they are more suitable for high-power applications. But considering the high safety requirement of some scenarios and the compatibility of existing technologies, such as hazardous materials warehouse, mining, military back up will still be long-term use of lead-acid. Both have their own advantages and will coexist for a long time.
How are the energy densities of lead-acid batteries and sodium batteries?
The weight energy density of lead-acid battery is about 35~50Wh/Kg, while sodium battery is about 90~150wh/Kg; The volume energy density of lead-acid battery is about 100Wh/L, while sodium battery is about 220~350Wh/L. The same weight/volume of a sodium battery can store 2~3X energy of a lead-acid. Thus is why our SIB is 60% lighter than a lead acid.
What are the self-discharge rates difference between lead acid and sodium? Which one can still maintain a higher SOC after long-term storage?
At room temperature, a MF lead-acid self-discharge is about 5% per month, and a AGM about 3% while a sodium battery is only 2~3%. Therefore sodium batteries have a longer shelf life.
Why do lithium batteries cause damage to alternators and other low-voltage electrical components?
Because lithium batteries require a lot of safe protection on BMS hardware, such as OCP (over current protection), OVP (over voltage protection), etc, MOS or relays are used to control the on/off of the entire circuit; When the sensor detects an abnormality, the BMS chip will drive the MOS or relay to open. This sudden opening action will generate a spike in voltage and current (in miliseconds), causing the Alternator and ECU to burn out. The main improvement method for this issue is to add capacitors to the BMS system hardware to absorb these peak voltages. But this approach has obvious drawbacks, such as further increasing
structuralcomplexity and cost, and reducing reliability, compatibility, and lower costs.
