70Ah Prismatic Cell

The 70Ah sodium-ion prismatic cell is designed for compact industrial battery systems, mobile equipment and energy storage applications where size, power and reliability matter. With 203 Wh of nominal energy and a nominal voltage of 2.9V, the cell gives battery developers and system integrators a practical sodium-ion format for space-constrained pack designs.

The 70Ah sodium-ion prismatic cell uses NaCrO₂ sodium chromium oxide chemistry, which supports stable operation and a safety-focused battery architecture. This makes the cell suitable for applications where thermal behaviour, reliability and system-level safety are important. Typical use cases include AGVs, robotics, mobile power units, compact energy storage systems and industrial equipment.

Low-temperature performance is one of the key strengths of this cell. The 70Ah cell retains more than 90% capacity at -40°C, which makes it relevant for outdoor equipment, warehouse automation, cold-chain logistics and cold-climate industrial systems. In suitable designs, this performance can reduce the need for additional thermal support and help simplify the overall battery system.

The 70Ah sodium-ion prismatic cell also supports demanding power profiles. It provides 2C continuous discharge and up to 4C pulse discharge, allowing it to handle applications with sudden power demand or dynamic load behaviour. This makes the cell relevant for automated guided vehicles, robotics, material handling equipment and mobile industrial platforms.

Efficiency is another important factor for compact battery systems. With round-trip efficiency above 96%, the cell helps reduce energy losses during charge and discharge cycles. Lower losses can support reduced heat generation and improved system durability when the battery operates within the correct voltage, current and temperature range.

From a logistics perspective, the cell supports 0V zero-voltage shipping. This can simplify transportation, storage and inventory planning for manufacturers, distributors and system integrators. It also gives project teams more flexibility when managing long-term stock or international battery supply chains.

The prismatic format supports efficient module integration. Its flat geometry helps improve space utilization in compact enclosures, while compatibility with laser welding supports strong, low-resistance electrical connections. This is useful in industrial environments where vibration, mechanical reliability and production consistency matter.

The 70Ah sodium-ion prismatic cell is certified according to UN38.3 and CE requirements. AuroraCell supports European customers with local EU stock availability and standard delivery options, subject to stock and project requirements. This helps reduce sourcing complexity for teams evaluating sodium-ion technology in Europe.

Typical applications include warehouse robotics, AGVs, mobile power units, off-grid energy systems, compact industrial equipment and modular battery packs. For engineers looking for a compact sodium-ion battery cell with strong power capability, the 70Ah sodium-ion prismatic cell offers a practical option for evaluation, system integration and project-specific battery development.
