J7N0700-S01 Sodium-ion Battery Cell Specification

This document is the product specification for the rechargeable sodium-ion battery cell model J7N0700-S01 from Li-Fun Technology Co., Ltd. It is intended for use in electric vehicles (EV), energy storage systems (ESS), or other specified applications. Key specifications include a nominal voltage of 2.85V, charge voltage of 3.3V, minimal capacity of 180 Ah (typical 183 Ah) at 0.5C discharge, and a cell weight of approximately 5.7±0.1 kg. The standard charging method is CC/CV at 0.2C to 3.3V with a cut-off at 0.05C, taking about 5 hours. Maximum continuous charge and discharge power is 0.5P at room temperature, with a pulse discharge current up to 5C for ≤10 seconds. Discharge cut-off voltage is 1.5V above 0°C and 1.0V at or below 0°C. Operating temperature ranges from 0 to 45°C for charging and -40 to 60°C for discharging. Storage conditions vary by temperature and duration, with recovery capacity ≥90% after specified periods. ACIR at 50% SOC is ≤0.5 mohm. The document also includes amendment records, performance specifications, safety guidelines, and application instructions such as welding parameters and handling cautions.
