Songjin Textile Technology (Shanghai) Develops Ultra-high Temperature Battery Protection Panels for New Energy Vehicles And High-speed Trains

Songjin Textile Technology (Shanghai) Co., Ltd. has successfully developed an ultra-high temperature battery protection board, bringing revolutionary changes to the thermal runaway protection of new energy vehicles and high-speed rail power battery systems. This advanced material has a thickness of only 0.5-1mm and can withstand extreme temperatures of 1000-1400 ° C, extending the fire resistance time from the current 5 minutes to over 30 minutes. This breakthrough ensures that passengers can evacuate and rescue more safely in the event of a battery thermal accident.

Currently, mainstream thermal runaway protection solutions for NEV battery modules rely on composite materials such as aerogel, flame-retardant foam, and mica plates, which act as thermal barriers between cells. However, existing solutions have limitations in prolonged high-temperature resistance. According to GGII, the demand for flame-retardant insulation materials in NEV battery packs reached 6.75 million square meters for upper covers and 6.71 million square meters for inter-module layers in 2022. Meanwhile, Frost Sullivan reports that the global NEV mica material market hit **RMB 1.73 billion in 2022, with a CAGR of 86.40% from 2017-2022, and projects a 37.60% CAGR from 2023-2027

SONKIN®️ new battery protection board, scheduled for completion by the end of 2024, is designed to meet the stringent safety requirements of next-generation NEVs and high-speed rail energy storage systems. By enhancing fire resistance and thermal insulation, this innovation will play a critical role in mitigating battery thermal runaway risks, aligning with global automotive and rail safety standards.
