The CNAE 32140NaR-MP10Ah is a rechargeable 32140-format sodium-ion cell rated at 3.0 V and 10.0 Ah under the manufacturer's specified capacity test. It combines a cylindrical form factor with temperature-dependent charging and discharging characteristics for engineered battery assemblies. MisenBattery supplies the CNAE-manufactured cell and supports custom pack integration; system designers should select charging limits, current profiles and protection settings against the applicable CNAE specification and obtain clarification of its differing voltage and current statements.
CNAE identifies this model as a cylindrical sodium-ion cell in its Na2FeP2O7-series cathode family. Its nominal voltage is 3.0 V, and nominal capacity is 10.0 Ah when discharged at 0.5C and 25°C over the manufacturer's stated capacity-test window. These are cell-level specifications, so the voltage and capacity of a finished assembly depend on its series-parallel configuration and operating limits.
The specified overall size is 33.2 ± 0.2 mm in diameter and 140.0 ± 0.3 mm in height, with a cell weight of 260 ± 5 g. Multiplying the nominal 3.0 V by 10.0 Ah gives approximately 30 Wh of nominal cell energy. Pack designers should allow for the stated tolerances, terminal connections, insulation and mechanical retention rather than treating the nominal format code as an exact envelope.
The detailed discharge table specifies 3C continuous operation at 25°C with at least 90% relative capacity under its test conditions. It separately defines 10C for 30 seconds and 15C for 3 seconds when SOC exceeds 50% and the specified cell-surface temperature requirements are met. These short-duration values must not be used as continuous pack ratings; thermal performance and current limits require application-level validation.
CNAE lists a −40°C to 70°C discharge-temperature range and provides separate maximum discharge-rate guidance by cell temperature and state of charge. The safety instructions specify charging from 0°C to 60°C, with allowable charging rates changing across temperature and SOC bands. A pack controller should monitor cell temperature and reduce or stop current as required; the broad discharge range does not imply full-rate performance throughout.
The specification gives AC internal resistance of no more than 3 mΩ at 1 kHz and 3.2 V. It also lists DC resistance of no more than 10 mΩ under a 2C, 30-second test at 3.2 V. These figures use different measurement methods and are not interchangeable. Matching cells by appropriate measured parameters can support more consistent pack assembly and subsequent electrical verification.
CNAE's normal-temperature performance table lists at least 4,000 cycles with at least 70% remaining capacity. However, the later cycle-test procedure specifies a different charge and discharge voltage window from the performance-table condition. Treat the cycle figure as a manufacturer-reported test indicator, not a guaranteed service life for every pack duty cycle. Confirm the applicable acceptance method with CNAE before setting a project requirement.
Custom battery pack applications: For manufacturer-approved stationary or industrial systems within the specified operating conditions, MisenBattery supplies CNAE cells and supports custom pack integration. Design considerations include a sodium-ion-compatible BMS, fuse protection, welded interconnects, voltage and temperature sensing, insulation, spacing and thermal management. Confirm application suitability and the differing charger-voltage and high-current statements with CNAE before finalizing the design. Request product- and shipment-specific compliance documentation where applicable; no certification is implied by this listing.
