Core Viewpoint - The article emphasizes the advantages of the full ear technology in high-power cylindrical lithium batteries, which effectively reduces internal resistance and heat generation, addressing the thermal management challenges of high energy density cells, thus paving the way for broader applications in high-power scenarios [1][2]. Group 1: Full Ear Technology - Full ear technology transforms the entire positive and negative electrode current collectors into ears, significantly shortening the electron migration path, which reduces internal resistance by 80% compared to traditional cells [2][3]. - This technology addresses the limitations of traditional cylindrical batteries, which face high internal resistance and heat generation, making them unsuitable for sustained high-efficiency output in high-power applications [2]. Group 2: Jumbo Power Series - The company has launched the Jumbo Power series cylindrical lithium batteries, with the JP40 model achieving global mass production, providing powerful energy solutions for leading electric tool brands [3]. - The JP30 model, introduced in December 2024, meets the demand for smaller tools while significantly enhancing operational precision and efficiency, with a notable increase in capacity compared to traditional 18650 batteries [3]. Group 3: Performance Enhancements - The JP30 battery supports super-fast charging, reaching 80% charge in just 10 minutes and can operate at temperatures up to 60°C, reducing the number of batteries needed for outdoor work from 12 to 2-3 [3]. - The JP series batteries achieve comprehensive improvements in five key performance indicators: high power, long runtime, high charging efficiency, long lifespan, and low-temperature performance, utilizing advanced materials and design [3].
