OID SIB50160118-50H 2.85V 50Ah Sodium-Ion Prismatic Cell with 8000-10000 Cycles and -40C Low Temperature Performance

OID SIB50160118-50H 2.85V 50Ah Sodium-Ion Prismatic Power Cell

If you are designing energy storage or start-up power systems for cold climates, high-rate applications, or long-life industrial use, traditional lead-acid batteries often fail early, lose capacity in winter, and require frequent replacement. The OID SIB50160118-50H-2.85V-6C-1602 sodium-ion power cell from Jianheng is engineered to solve exactly these problems. It combines the inherent safety of sodium-ion chemistry with a nominal voltage of 2.85 V, a nominal capacity of 50 Ah at 0.2C, continuous discharge up to 6C, 45-second pulse discharge up to 10C, and a cycle life of 8000 to 10000 cycles. It retains approximately 90% of initial capacity at -20C discharge and approaches 90% even at -40C, making it a true low-temperature power solution.

Whether you are building high-safety residential energy storage, industrial energy storage, low-temperature discharge and charging start-up power sources, or high-rate long-cycle start-up power for forklifts, engineering vehicles, motorcycles, and trucks, this cell delivers reliable performance. It supports 0 V activation charging for safe recovery from deep discharge, operates from -40C to 60C, and features a stable prismatic aluminum-shell design tested under 0.2 MPa pressure cycling.

Performance Test Data

Storage and Transportation

The cell must be stored separately in a cool (≤ 25 °C) dry area for long-term storage, away from direct sunlight, heated environments and high static environments. The battery must be kept away from children or pets. For storage, a 50% SOC cell stored at 40 °C for 1 month, 30 °C for 2 months, or 20 °C for 3 months can recover ≥ 90% capacity at room temperature using the standard charge and discharge mode. During transport, the positive (+) and negative (-) directions must be checked before packaging, and insulation must be verified to prevent short circuits when wiring boards or wires are connected to the battery. The cell must not be exposed to temperatures outside the specified operating temperature range. When monomers are used for module or component assembly, the first-in, first-out principle should be adopted. The cell must not be soaked or wetted by water or seawater, and must not be placed in microwave ovens or high-voltage containers.

Warranty

Jianheng warrants that the SIB50160118-50H-2.85V-6C-1602 sodium-ion cell is free from defects in materials and workmanship under normal use and service for a period of 12 months from the date of shipment or 24 months from the date of manufacture, whichever occurs first, unless otherwise agreed in writing. The warranty is subject to the cell being stored, charged, discharged and operated strictly in accordance with this specification, including the specified temperature ranges, charge and discharge limits, and handling requirements. The warranty does not cover damage resulting from overcharge, over-discharge, external short circuit, mechanical abuse, immersion in water or seawater, use with incompatible chargers or battery systems, mixing old and new cells, disassembly, or any use outside the specified operating conditions. The warranty is limited to replacement or repair of defective cells at Jianheng's discretion and does not cover consequential or incidental damages. Any matters not covered in this specification shall be negotiated with Jianheng.

Warnings

The following warnings apply to the use of this sodium-ion rechargeable cell. Incorrect use may lead to heating, fire and performance degradation. Please refer to the user manual before using applications with the battery, and read the specific charger manual before charging. Stop charging when the battery does not charge after prolonged contact with the charger. Check the positive (+) and negative (-) directions before packaging, and verify insulation to avoid short circuits when connecting wiring boards or wires. Do not use different chargers; do not charge beyond the maximum charging current; do not disassemble or reinstall the battery; do not throw or cause impact; do not pierce the battery with sharp objects such as nails, knives, pencils or drills; do not use the cell together with other battery systems; do not package old and new batteries together; do not expose the battery to high temperatures such as fire; do not put the battery in a microwave oven or high-voltage container; do not use the battery in violation of regulations; do not connect the positive (+) and negative (-) terminals with conductive materials such as metals or wires; do not allow the battery to be soaked or wet by water or seawater. Do not place the battery in direct sunlight or heated environments; do not use batteries in high static environments; batteries must be kept away from children or pets. When rust or odor is detected during first use, return the product to the seller immediately. When battery life shortens after prolonged use, replace it with a new battery. Do not wear metal objects such as wristbands or watches when handling batteries. The charging time shall not exceed the time specified in the manual. Do not expose the battery outside the operating temperature range specified in this document. For any matters not covered in this specification, please consult with Jianheng.

Applications and User Value

In cold-chain logistics, winter construction, and remote telecom sites, lead-acid batteries can lose more than half their capacity at -20C and fail completely at -40C. The OID sodium-ion cell retains approximately 90% capacity at -40C, so your equipment starts reliably even in extreme cold. For forklift fleets and engineering vehicles, the 6C continuous and 10C pulse discharge capability provides the burst power needed for start-up and heavy loads, while the 8000 to 10000 cycle life reduces battery replacement frequency and total cost of ownership. In residential and industrial energy storage, the inherent safety of sodium-ion chemistry and the stable 0.2 MPa pressure cycling behavior give you peace of mind. The 0 V activation charging feature allows safe recovery from deep discharge, protecting your investment. With UN38.3 and MSDS certification, this cell is ready for global transport and deployment.
