CBAK Energy has Successfully Developed Large-sized Cylindrical Tabless Battery with 25% Boost in Energy Density and 20% Cost Saving

DALIAN,China,Sept. 28,2020 -- CBAK Energy Technology,Inc. ("CBAK Energy",NASDAQ: CBAT),a world's leading lithium-ion battery manufacturer and electric energy solution provider,announced that its product release of 32140 large-sized cylindrical tabless battery has officially passed its technical and Pilot Plant tests which demonstrated its success in product research of this model. As the requirement of mass production on this product has been achieved,CBAK Energy is planning for the construction of new standardized production line which aims to achieve mass product delivery in the first half of 2021.

The research and development 32140 large-sized cylindrical battery is the main focus of CBAK Energy in recent years. Compared to previous 26650 model,the energy capacity of one single cell increased 5 times as well as 25% increase in energy density and 20% reduction in cost per kilowatts. Meanwhile,the new model will have three different versions with three different anode systems in order to fulfill the need of different markets which are NCM,LiFePO4 and LiMn2O4.

The tabless design of the battery has dramatically reduced its internal resistance which also sufficiently solved the problem of heat dissipation in large-sized lithium-ion battery. In comparison with Tesla's cathode tabless design in its 4680 model,CBAK's tabless design has been applied to both anode and cathode of the battery which greatly improved the performance of each single cell. By optimizing manufacturing process,the difficulty in electrolyte drenching has been accomplished which also solved the problem in design space loss when using tabless design.

"Large-sized cylindrical battery becomes very competitive in electric vehicle and energy storage market according to its high energy density,extremely low internal resistance and material cost and high durability. In the meantime,CBAK is developing more new series of large-sized batteries with better performance and lower cost for the sake of the need of the market," said Mr. Yunfei Li,the CEO of CBAK Energy.
