全球首发！350Wh/Kg固态圆柱电池量产在即

Group 1 - The core viewpoint of the article highlights the global launch of Jiangsu Tianpeng Power's 350Wh/Kg solid-state cylindrical battery, which is primarily aimed at applications in fields such as embodied robots, low-altitude aircraft, and e-Bikes [1][4]. - The newly released solid-state 60HES battery cell utilizes revolutionary materials and structural designs, featuring a high nickel ternary material (NCMA Ni93) for the positive electrode and a low-expansion silicon-carbon negative electrode (SiC), enabling higher capacity and energy density [2]. - The 21700-60HES cell has a nominal capacity of 6100mAh, supports 1C/3C charge and discharge capabilities, achieves an energy density of 350Wh/Kg, and has a cycle life of over 800 at room temperature, with stable operation in a temperature range of -10℃ to 65℃ [3]. Group 2 - The battery has completed safety verification with leading international clients, receiving high recognition for its performance, and mass production validation is currently underway, expected to be fully completed by the end of this year, transitioning from pilot production to the global market [4]. - Tianpeng Power is also developing the next generation of solid-state batteries, aiming for mass production of batteries with an energy density exceeding 500Wh/kg by 2027, utilizing a composite solid electrolyte compatible with cylindrical cells (sulfide + polymer) [5]. - Tianpeng Power, a wholly-owned subsidiary of Weilan Lithium, focuses on the research, production, and sales of cylindrical batteries, forming a lithium battery technology and product system that includes NCM, NCA, and LFP technologies [6]. Group 3 - Tianpeng Power has four major production bases, with three located in Jiangsu Province and one in Selangor, Malaysia, which plans to invest $280 million to achieve an annual production capacity of 10GWh of cylindrical lithium batteries [6]. - The Malaysian base officially opened on April 29 this year, with an initial total capacity of approximately 400 million cells per year, and stable supply of 18650 and 21700 cell types has been achieved, with plans to produce high-end models such as 5.8Ah and 6.5Ah in the future [6].
