Prismatic Sodium-Ion Cell Specs: NaPPSD15121325-37

This document specifies the dimensions, characteristics, technical requirements, and precautions for the prismatic sodium-ion cell model NaPPSD15121325-37, produced by HuNan Naneng Era Technology Development Company Limited. The cell has a nominal capacity of 37Ah and a typical capacity of 38.5Ah at 0.5C discharge, with a nominal voltage of 2.85V. Charge cut-off voltage is 3.25±0.05V, and discharge end voltage is 1.5±0.05V. Dimensions are 121.0±0.2mm width, 15.5±0.5mm thickness, and 417.0±5.0mm length including tabs. Energy density is ≥100Wh/Kg, and weight is 1.1±0.2Kg. Operating temperature ranges from -20°C to 60°C for charging and -40°C to 60°C for discharging. Electrical performance includes rate discharge capability (1.0C/0.5C ≥97%, 2.0C/0.5C ≥96%), cycle life of 8,000 cycles with ≥70% capacity retention, high and low temperature discharge performance, and storage performance with retained capacity ≥95% and recovered capacity ≥98%. Safety tests cover vibration, heating, short circuit, overcharge, overdischarge, and heavy object impact, all requiring no fire, no explosion, and no electrolyte leakage. Precautions include applying ≥100Kgf pressure during use, avoiding water immersion, using dedicated chargers, and preventing short circuits. The cell complies with environmental substance control requirements.
