In an era that demands efficiency and quality, Jiangsu Reliance Energy is spearheading a revolution in power tools, committed to advancing the industry. Our tabless battery technology embodies this promise. Recognizing the limitations of conventional battery technologies, we continuously innovate to deliver the following core advantages:
Tabless Technology: A New Chapter for High-Performance Batteries
In the exploration of battery technology, Reliance Energy remains at the forefront. Our groundbreaking innovation—tabless technology—redefines conventional battery design.
In conventional batteries, tabs, as critical components for current collection, not only increase internal resistance but also limit high-rate discharge capabilities. Cylindrical batteries, plagued by impedance issues, have long been confined to the 18650 product series. Even the 21700, after its introduction, failed to leverage its higher energy density due to excessive structural impedance, rendering its actual capacity impractical for high-power applications.
The tabless design, enabled by advanced manufacturing processes, achieves direct and uniform current distribution within the battery, significantly reducing internal resistance and enhancing charge-discharge efficiency. This breakthrough unlocks unprecedented power performance for power tools. However, overcoming structural impedance poses unprecedented challenges across materials, chemical systems, welding methods, and process control capabilities for high-power battery manufacturers. Reliance’s core team, drawing on over a decade of expertise in high-power/high-energy premium cylindrical products and supported by industry-leading R&D and engineering teams, has meticulously explored the full potential of tabless technology!
From its inception, Reliance Energy has focused on pioneering tabless technology. Leveraging its team’s profound technical expertise and mastery of full-process know-how in premium cylindrical batteries, the company aims to deliver hexagonal all-round products to global clients—combining ultra-high energy density, ultra-high power, extreme vibration resistance, super-fast charging, ultra-low-temperature performance, and unparalleled safety.
Reliance Energy has developed every aspect from scratch: material innovation, electrochemical platforms, structural failure risk mitigation, dual optimization for extreme high/low temperatures, and safety-focused component design. Embracing AI-driven upgrades across its R&D system, the company has created a series of internationally leading products that exceed customer expectations.
Extended Runtime: Say Goodbye to Frequent Charging
For professional users, extended runtime is indispensable. Reliance Energy’s tabless batteries, with their exceptional energy density and efficient energy conversion, dramatically prolong the single-use duration of power tools. Whether for continuous drilling in home renovations or high-intensity cutting in outdoor operations, these batteries eliminate the hassle of frequent charging, ensuring smoother and more efficient workflows.
Durability: Long-Lasting Companionship for Every Success
Beyond runtime, battery longevity is a key user concern. Reliance Energy’s tabless batteries optimize internal structures to reduce aging caused by tab overheating, mechanical stress, and other factors, significantly extending cycle life. This means your tools will endure longer, serving as reliable partners in daily maintenance or major projects.
Broad Operating Temperature Range: Thriving in Harsh Environments
The variability of work environments demands robust battery performance. Reliance Energy’s tabless batteries excel in thermal management, maintaining stable output across a wide temperature spectrum. Whether in freezing winter construction sites or scorching summer outdoor tasks, they ensure uninterrupted tool operation, empowering users to perform optimally in any condition.
Breaking Performance Barriers, Unleashing Unmatched Power
Jiangsu Reliance Energy, centered on tabless technology, delivers an unprecedented leap in performance for power tools. Our batteries not only offer extended runtime, enhanced durability, and broader temperature adaptability but, most importantly, shatter performance bottlenecks to unleash unmatched power. In professional scenarios, this translates to revolutionary efficiency and creative freedom, fueling every success and breakthrough.
