Solid-State Sodium Salt Battery Manufacturing and Application Technology

This document presents the manufacturing and application technology of solid-state sodium salt batteries by Inner Mongolia Jianheng Aoneng Technology Co., Ltd. The company, located in Ordos, Inner Mongolia, has completed a 300MWh automated production line with plans to expand to 3GWh. The battery design principles are based on β''-Al2O3 solid electrolyte, which allows selective conduction of sodium ions while blocking electrons, ensuring safety. Key features include high safety (no fire, passes USABC tests), high specific energy (150 Wh/kg, 330 Wh/L), 100% Coulombic efficiency, no self-discharge, long cycle life (>4500 cycles at 80% DOD), wide temperature tolerance (-40 to 60°C), and 100% recyclable materials. Applications span energy storage and reserve power markets. Compared to other batteries, sodium salt batteries offer superior safety, longevity, and environmental friendliness, making them ideal for stationary storage.
