BAK Battery Released a New Generation of 21700 Continuous Tab Series Small Power Battery
*SHENZHEN, CHINA / ACCESSWIRE / March 29, 2024 / *On March 27, BAK Battery released its new generation of continuous tab series small power battery. It features a set of configurations guaranteeing both high power and high capacity，and targets the three major market segments of smart life, power tools, and micromobility, eliminating the *disadvantages of smart terminals, such as short battery life, insufficient power, and slow charging. *This helps in delivering a fresh user experience. This new product adopts the same continuous tab design as the big cylindrical battery, exploring a new path to improve the high-power performance of lithium-ion batteries.BAK Battery has been devoting itself to the research and development of cylindrical lithium-ion batteries for over two decades, during which three generations of small power batteries were successfully developed. It differs from the 1st generation with a traditional single tab structure and the 2nd generation with a double tab structure, BAK's 3rd-generation small power battery with a continuous tab design features high power, small internal resistance, low temperature rise, fast charging, long cycle life, and high capacity. Its maximum charge and discharge currents have increased to 5C and 25C respectively, and its operating temperature range has extended from -40°C to 80°C. It is durable and can be applied in more scenarios by eliminating the pain point of large internal resistance in traditional cylindrical battery structures and reduction of charging time.
The three new products released by BAK offer different characteristics to accurately eliminate pain points in market segments. INR21700-40D is designed for the most demanding professional electric tools. It has a higher charge/discharge rate, achieving 100 A sustained discharge and 140 A pulse discharge, can be fully charged in 12 minutes, and has battery life up to 600 cycles. Compared with traditional 4.0 Ah lithium-ion batteries for power tools, this product's internal resistance is reduced by 80%, discharge current increased by 120%, and cycle life extended by 140%.
INR21700-45D serves consumer electronics and household electric tools (such as those for smart cleaning) and micromobility vehicles (such as electric motorcycles). It balances high capacity and high power to increase battery life and energy utilization. Its sustained discharge current can reach 70 A, while its internal resistance is only 3.4 mΩ, which, together with a full charge time of just 15 minutes, makes it highly suitable for various smart life scenarios.
INR21700-50D is developed for electric motorcycles running on beaches, offroad, on professional racing tracks, and under other special conditions. It offers a higher capacity of 5.0 Ah, 60 A sustained discharge current, and 100 A pulse discharge current, meeting the needs of high-speed electric motorcycles for long battery life and instantaneous high-current acceleration. It also supports discharge at an ultra-low temperature of -40°C. Its 3.6 mΩ internal resistance achieves efficient heat dissipation and it can be charged to 80% in 15 minutes, accelerating electrification in the micromobility sector and realizing stress free travel.
Based on these three new products, BAK Battery will make efforts in both professional and consumer markets and expand its breadth and depth in the industry without ceasing, providing end users with a refreshing experience.
Song Huajie, the head of small power product development at BAK Battery, said that, "BAK Battery always maintains a keen insight into market changes. *As our lifestyle is powered by technology, electric terminal devices appear everywhere in our life. In the future, mobile intelligent terminal devices with stronger computing power and richer features will be applied more to our daily life. The performance of the lithium-ion battery, which is one of core components of those devices, will determine the "forms" of intelligent terminal products and the "boundaries" of usage scenarios. *The release of this new generation of continuous tab small power battery not only strongly demonstrates the technological strength of BAK Battery, *but also expresses our commitment to empower those scenarios with further technological innovation to further enhance market application and the end user experience."*
