Sodium-Ion Battery Cells / 10 Ah
10 Ah / Cylindrical / Layered oxide
32140 High-Power Sodium-Ion Cell
High current. Cold-weather readiness. The AuroraCell 32140 sodium-ion cell combines 10Ah capacity with up to 180A continuous discharge, 300A pulse discharge for 3 seconds and controlled charging below zero.
Cell-specific advantages
Built for demanding power applications.
Charge down to −20°C
Controlled sub-zero charging can reduce preheating demand and help outdoor systems stay ready. The BMS applies the datasheet’s temperature-dependent charging limits.
A flexible 10Ah building block
The cylindrical format, 30Wh energy and 3.0V nominal voltage support modular pack configurations for robotics, industrial mobility, backup and starter applications.

Product questions
From specification to application.
Can this sodium-ion cell charge below freezing?
Yes. The 32140 supports controlled charging down to −20°C within the datasheet’s current, voltage and state-of-charge limits. This is a cell-specific capability.
What is the difference between its continuous and pulse ratings?
At 10°C to 45°C, the specified maximum is 180A continuously or 300A for a 3-second pulse. Temperature-specific limits are provided in the technical datasheet.
