/PRZWT/SHENZHEN, March 20, 2025 - As the energy industry accelerates its transition to clean, low-carbon, and high-efficiency, cylindrical batteries have become an indispensable "energy capsule" in modern society, and end-point applications require even more extreme battery performance. In this context, the all-polar ear battery technology with low internal resistance and high power has become the optimal solution for the pursuit of high-performance products. Recently, BAK Battery officially released the all-polar ear 18650 D series products, which have been fully upgraded in performance and lead the user experience to a new height.
Six major performance upgrades to handle complex working conditions calmly
18650 battery has a wide range of application scenarios, especially in the field of power tools, in the face of endless complex working conditions, BAK power full pole ear 18650-30D battery will rely on high safety, high power, long battery life, long cycle, fast charging and wide temperature six characteristics, far beyond the excellent performance of traditional products, leading the end point experience upgrade.
In terms of safety, BAK batteries start from both the structure and the material. The full-pole ear structure makes the current density more uniform and improves the heat dissipation capacity. In terms of materials, BAK batteries use multi-doped cathode materials to improve the stability of the cell structure. At the same time, with a high heat-resistant diaphragm, the risk of deformation of the battery in a high-temperature environment is effectively reduced, and the safety of the battery under various operating conditions is fully guarded.
BAK Power full-pole ear 18650-30D battery, internal resistance is less than 5mΩ, discharge capacity enhancement 100%, support maximum 60A continuous discharge, can continue to discharge with maximum pulse current 120A within 10s, easily cope with extremely complex work tasks. At the same time, it has a high capacity of 3.0Ah, energy density up to 250Wh/Kg, support 30A continuous discharge, and battery life is increased by 30%. In addition, the cycle life of the new product is equally excellent, support 8A charging 30A discharge, cycle 600 weeks, double the performance. In terms of charging speed, it only takes 9 minutes to charge from 10% to 80%, and the speed is increased by 200% to achieve higher work efficiency.
In addition, this product can be discharged at -40 ° C to 80 ° C, challenging a wider temperature range.
Three dimensions of innovation are deeply cultivated, and professionalism creates excellent quality
Behind the excellent performance is persistent innovation and research and development. BAK Battery began to deploy full-pole ear technology as early as 2019. After years of intensive research and development, it has built a comprehensive innovation system in three dimensions: design concept, production process, and intelligent manufacturing model.
All-pole ear 18650 D series products came out, and BAK Battery officially formed a full matrix product system covering 18 series, 21 series and 46 series. The excellent performance of all-pole ear products will cover application scenarios in different fields, meet the needs of diverse mobile end point products, and promote the transformation and upgrading of smart lifestyle....
