At a time when the energy industry is accelerating its transformation towards clean, low-carbon and high-efficiency, cylindrical batteries have become an indispensable "energy capsule" in modern society, and terminal application products have even more extreme requirements for battery performance. In this context, full-pole-ear battery technology with characteristics such as low internal resistance and high power has become the optimal solution for pursuing high product performance. Recently, BAK Battery officially released the full-pole-ear 18650 D series products, which have achieved comprehensive performance upgrades and led user experience to a new level.

18650 battery have a wide range of application scenarios, especially in the field of power tools. Faced with an endless stream of complex working conditions, BAK's full-pole-ear 18650-30D battery will rely on six major characteristics of high safety, high power, long battery life, long cycle, fast charging and wide temperature range, with outstanding performance far exceeding traditional products, leading the terminal experience upgrade.

In terms of safety, BAK starts from both structure and materials. The full-ear structure makes the current density more uniform and improves the heat dissipation capacity. In terms of materials, BAK uses multi-doped positive electrode materials to improve the stability of the battery cell structure. At the same time, with high heat-resistant diaphragms, it effectively reduces the risk of battery deformation in high temperature environments, and comprehensively protects the safety of the battery under various working conditions.

BAK full-pole ear 18650-30D battery has an internal resistance of less than 5mΩ, a 100% increase in discharge capacity, supports a maximum continuous discharge of 60A, and can discharge continuously at a maximum pulse current of 120A within 10s, making it easy to cope with extremely complex work tasks. At the same time, it has a high capacity of 3.0Ah, an energy density of up to 250Wh/Kg, supports 30A continuous discharge, and a 30% increase in battery life. In addition, the cycle life of the new product is also excellent, supporting 8A charging and 30A discharging, 600 cycles, and doubled performance. In terms of charging speed, it only takes 9 minutes to charge from 10% to 80%, a 200% increase in speed, and higher work efficiency. In addition, this product can be discharged at -40℃ to 80℃, challenging a wider temperature range.
