\"\"<\/figure>\n\n

Post-event, Reliance Energy Tech and Carl Zeiss (Shanghai) Management Co., Ltd. signed a strategic agreement to co-establish a Battery Quality Innovation Lab. Leveraging Zeiss\u2019 century-long expertise in precision measurement and Reliance\u2019s innovation in new energy, the partnership will drive deep technical synergy across R&D, production, and lifecycle quality control.<\/p>\n\n

\"\"<\/figure>\n\n
\"\"<\/figure>\n\n

This collaboration not only establishes regularized cooperation mechanisms in areas such as inspection equipment procurement and joint talent development programs, but will also champion Chinese new energy industry quality standards in global markets through a joint branding initiative.<\/p>\n\n

Moving forward, both parties will leverage technology symbiosis to accelerate industrial upgrading, injecting powerful impetus into high-quality development across the global new energy sector.<\/p>\n\n

\"\"<\/figure>\n\n

With the launch of the 21700-6.0Ah battery and the commencement of the Reliance-ZEISS strategic partnership, Reliance Energy Tech is accelerating its global expansion through a dual-engine strategy powered by ‘Technology + Quality’.<\/p>\n\n

“300Wh\/kg is not the destination, but the starting point of a new journey,”stated Chen Xuan. “We look forward to partnering with global innovators to accelerate the energy transition<\/strong>.”<\/p>\n\n
