Lithium battery BMS can have problems if there are not enough materials or if prices go up. Most lithium, cobalt, and nickel come from just a few countries. If something happens in those places, prices can rise quickly. For example, lithium prices went up by over 400% in one year. This makes it hard for companies to plan and keep prices low.
Sodium battery BMS does not have these problems. Sodium is easy to find and cheap. Aluminum, used in sodium battery BMS, is also easy to get. This means the price of sodium battery BMS stays steady over time. Companies and homeowners can expect stable costs and fewer surprises.
Sodium battery BMS also needs less fixing and has fewer parts that break fast. This means you do not have to replace or repair it as much. Over time, these savings make sodium battery BMS a good choice for long-term value.
Note: More people want electric vehicles, so there may not be enough lithium and other key materials by 2027. Sodium battery BMS helps avoid these problems by using materials that are easy to find.
Energy density means how much energy a battery can store for its size or weight. This is important for things like phones and electric cars. These devices need batteries that are small and light. The table below shows how much energy sodium-ion and lithium-ion batteries can hold in 2025:
Battery Type | Average Gravimetric Energy Density (Wh/kg) in 2025 |
|---|---|
Lithium-ion Battery | |
Sodium-ion Battery | 160 - 180 (current), potential up to 200 - 250 |
Lithium-ion batteries store more energy in each kilogram than sodium-ion batteries. They also keep high energy density after many charges, up to 1150 Wh/L. Sodium-ion batteries have less energy density. This means they are heavier and bigger for the same energy. So, sodium-ion batteries are not the best for portable electronics or cars. But sodium-ion batteries cost less and use easy-to-find materials. They are good for storing energy from solar or wind power, where size and weight do not matter as much.
Tip: Sodium-ion batteries are a cheap choice for big energy storage projects, especially when energy density is not the most important thing.
Cycle life tells us how many times a battery can charge and discharge before it gets weaker. If a battery has a longer cycle life, you do not need to replace it as often. This saves money on repairs and new batteries. Lithium-ion batteries last longer in real use. This helps lower costs over time, even though they cost more at first.
Sodium-ion batteries wear out faster because sodium ions are bigger. This puts more stress inside the battery and can make it wear out sooner. Both types lose power over time because of chemical changes. Smart battery management systems help by controlling charging, temperature, and keeping cells balanced. These systems make batteries last longer and reduce damage.
New cathode materials and electrolytes help sodium-ion batteries last longer.
Sodium-ion batteries often need less fixing and are easier to recycle.
Smart BMS stops overcharging and deep discharge, keeping batteries healthy.
Longer cycle life means you buy new batteries less often, saving money.
As sodium-ion batteries get better, the difference in how long they last and how much they cost compared to lithium batteries will get smaller, especially for big energy storage systems.
Safety is very important for battery systems. Sodium-ion batteries are safer because of their chemistry. They use electrolytes that do not catch fire easily. They can get hotter before having problems. Their battery management systems watch charge, voltage, and temperature closely. These systems use smart programs to find and stop problems early.
Lithium batteries need more safety parts. Their chemistry can catch fire if something goes wrong. Their BMS uses extra sensors and backup systems to keep things safe. These extra parts make the system safer but also cost more.
Here is a table comparing safety features:
Safety Feature | Sodium-ion Batteries | Lithium-ion Batteries |
|---|---|---|
Thermal Runaway Temp. | Lower (~270°C), more prone to thermal runaway | |
Electrolyte Safety | Aqueous/solid-state, less flammable | Organic solvents, more flammable |
BMS Monitoring | Precise, predictive algorithms | Extensive, with redundancy for higher risk |
Sodium-ion batteries pass hard safety tests. They can handle too much charging, short circuits, crushing, and fire without catching fire. This makes them safer for homes and big storage systems.
Note: Safer batteries mean less danger for people and lower costs for safety gear.
Sodium-ion batteries are better for the environment. Sodium is easy to find in seawater and the ground. Getting sodium does not hurt nature as much as getting lithium. Making sodium batteries uses less energy and fewer bad chemicals. This means less pollution and fewer carbon emissions.

Lithium Battery BMS gives better control and can be used for bigger grid storage. It is easier to add more batteries as needed. Sodium battery BMS is still a good and green choice for many grid projects. But its benefits get smaller as the system gets bigger and more complex.
Lithium Battery BMS uses some expensive metals. Copper, cobalt, and nickel are important in the system. Copper is the current collector. Cobalt and nickel help the battery work better and last longer. These metals cost more than aluminum in sodium battery systems. The table below shows how much copper and aluminum cost:
Material | Price per kg (USD) |
|---|---|
$7 - $8 | |
Aluminum current collector | $3 - $4 |
Getting lithium, cobalt, and nickel costs a lot. Processing these metals also adds to the price. Cobalt prices change a lot and can make batteries cost 60% more. Nickel might run out in the future, so prices could go up. Recycling these metals is hard and needs special machines. This makes recycling cost more money. Most of the cost in Lithium Battery BMS comes from these metals and recycling.
Getting and processing lithium, cobalt, and nickel costs more.
