About CORNEX

CORNEX New Energy Co., Ltd. was established in 2021 in Wuhan and is headquartered in Xiaogan, Hubei, with several plants in the province. It manufactures its own prismatic LFP energy storage cells (100Ah, 314Ah, 472Ah, 588Ah) and packages them into liquid-cooled packs, 20ft DC containers and outdoor C&I cabinets. The utility line consists of the M5 (PF173-314A-C5015L, 12 x 1P416S, 5,015 kWh, 2,500 kW, 314Ah cells) and the M6 (PF288-588A-C6262L, 8 x 1P416S, 6,262 kWh, 1,565 kW, 588Ah cells in CTP 3.0 module-free packs). Both are DC-side containers without integrated PCS, with liquid cooling/heating, IP55 enclosures and the 'Submerge' pack-level fire safety system. C&I products are the OTS02-H233L (233 kWh / 110 kW) and OTS03-H261L (261 kWh / 130 kW) liquid-cooled outdoor cabinets. Announced deliveries cover Europe, Israel, India and Southeast Asia. Not published: system-level round-trip efficiency, system cycle life, warranty terms, standard-numbered certification lists for the containers (product manual only says 'GB/UL/IEC/UN/NFPA'; the M5 press release cites GB/T 36276, IEC 62619 and UL9540A), M6 power ratings for its stated 2h scenario, and per-model datasheet PDFs beyond one combined product manual. No press kit or image licence exists; the site legal notice restricts commercial reuse of its content.
