Sodium-ion battery (sodium-ion battery) is a secondary battery (rechargeable battery) that mainly relies on Sodium ions to move between the positive and negative terminals to work, similar to the working principle of lithium-ion batteries. In the process of charging and discharging, Na+ is inserted and removed between the two electrodes: when charging, Na+ is removed from the positive electrode and embedded into the negative electrode through the electrolyte; The opposite is true for electrical discharge. The electrode material used in sodium-ion batteries is mainly sodium salt, which is more abundant and cheaper than lithium salt. Since sodium ions are larger than lithium ions, sodium-ion batteries are a cost-effective alternative when weight and energy density requirements are not high.
1. Safer
It will not fire or explode when facing extreme tests such as overcharge, overdischarge, short circuit, and needling.
2. 8 years service life
The cycle decay trend at 25ºC is stable, and the cycle life trend at normal temperature is far more than 3000 times (80%SOH). In theory, the battery life is up to 8 years, with a 3 yeas warranty.
3. High temperature cycle resistance
45ºC cycle decay trend is stable, high temperature cycle life trend is more than 3000 times (80%SOH) .
Waterproof exhaust valve with heat dissipation,Ensure the normal operation of the battery in high temperature areas.
4. High and low temperature discharge performance
Sodium-ion batteries have good high and low temperature discharge performance.
Discharge capacity retention rate ≥82% at -40ºC.
Discharge capacity retention rate ≥95% at 0ºC.
Discharge capacity retention rate ≥100% at 55ºC.
It better than lithium batteries.
5. Fast charging performance
Good magnification performance, fast charging, Charge 80% in 15 minutes .
6. Wide electric pressure range
Perfect solution to sodium ion battery voltage spike problem and low voltage protection .
7. Environmental protection
Without heavy metals such as lead, zinc and nickel
8. IP67 water proof
Not afraid of wind,sand,rain.
