Lithium-Ion vs Sodium-Ion Batteries: What’s the Difference?

Feature	Lithium-Ion Batteries	Sodium-Ion Batteries
Low Temperature Performance	Poor (<-20°C for LFP)	Excellent (-40°C to 60°C)
Thermal Runaway Risk	High (NMC/NCA), Moderate (LFP)	Very Low (intrinsically stable)
Recyclability	Complex (hazardous metals)	Easier (water-soluble components)
Carbon Footprint	High (mining-intensive)	Low (low-energy production)

Custom Sodium-Ion Battery Packs FAQ

Can energy density match lithium iron phosphate (LFP) batteries?

Yes, by 2025, sodium-ion batteries will reach 160-180 Wh/kg. Industry leader CATL is set to achieve 175 Wh/kg in mass production. This is close to LFP batteries, which range from 180-200 Wh/kg. These batteries can power small EVs for over 250 miles per charge. Key improvements include layered oxide cathodes and soft/hard carbon composite anodes, enhancing stability and efficiency.

Do Sodium-Ion Batteries solve winter range loss?

Absolutely. Sodium-ion batteries keep 85-95% capacity at -20°C (-4°F), much better than lithium batteries, which only retain about 60%. Special high-concentration electrolytes with cold-weather solvents, like ethyl acetate, allow for 93% capacity even at -40°C.

Where are they being used?

Our They are quickly expanding in:

Grid storage (e.g., China’s Datang Qianjiang project)
EVs (CATL-powered cars are now on the roads)
E-bikes (Yadea models charge in 15 minutes at -20°C)

Will they replace lead-acid or lithium batteries?

Vs. lead-acid: Sodium-ion offers 2-3 times more energy and lasts 4-6 times longer, with lifetime costs 70% lower. They’re ideal for e-bikes and starter batteries.

Vs. lithium: These batteries serve as a complement – not a full replacement. They excel in cold climates, budget EVs, and large-scale storage due to their cost and safety benefits.
