The educational tablet is a smart device designed for early childhood education, classroom learning for primary and secondary school students, and paperless teaching in schools. It features a high-definition touchscreen, stylus, high-resolution camera, and an AI-powered learning system, primarily used for online courses, e-textbook reading, exercise completion, personalized tutoring, online exams, and post-class video explanations. Powered by built-in lithium batteries, the device supports continuous operation of its CPU, display, and camera under heavy loads. Due to prolonged use throughout the day—whether at home, in classrooms, or during outdoor educational activities—the device requires exceptional battery endurance, excellent temperature resistance (both low and high temperatures), and high safety standards for long-term usage.
Home use scenarios: Early childhood education, online classes for students at home, evening practice and review sessions.
Campus Environment: Unified teaching terminals for classes, multimedia classrooms, and learning tablets used for campus inspections.
Outbound scenarios: educational trips, offline training sessions, mobile learning activities
Standard digital batteries paired with educational tablets are prone to various malfunctions during prolonged use, directly compromising user experience and the brand's after-sales reputation.
1. Rapid battery life degradation: Standard cells only withstand 300–500 charge cycles, with range halving after just one year of use; frequent battery replacements by users place significant pressure on manufacturers' after-sales services.
2. Performance issues under heavy load (including lag and battery drain): prolonged online course playback or running multiple apps simultaneously can cause high internal resistance, voltage spikes, flickering screens, touch sensitivity issues, or sudden device shutdowns.
3. Poor adaptability to temperature variations: In winter, the device exhibits immediate black screen and significant power consumption drop when powered on in low-temperature classrooms; during prolonged online classes in summer, the battery continuously generates heat, leading to bulging and electrolyte leakage.
4. Poor body compatibility: The battery cells are thick and inflexible, occupying valuable internal space in the device, resulting in a bulky overall design that cannot accommodate irregular-shaped bodies.
5. Significant safety hazards exist: substandard battery cells lack adequate protection, posing risks of short circuits and thermal runaway due to prolonged heating, and pose high risks when used by minors.
6. Long custom development cycle: Standard battery cells have fixed dimensions that cannot accommodate the irregular internal cavities of new tablet models, extending the product development timeline.
To address these industry challenges, lithium polymer cells designed for educational tablets must meet stringent performance requirements to fundamentally resolve operational issues.
1. Long cycle life: meets IEC standard cycles of ≥800 cycles, with slow capacity degradation during charging and discharging, reducing replacement frequency;
2. Stable discharge with low internal resistance: Featuring a low-resistance design that ensures minimal voltage drop under high-load conditions, delivering consistent output without lag or power loss.
3. Ultra-thin flexible packaging design: The battery cell is lightweight and highly adaptable, fitting seamlessly into various compact or irregularly shaped internal cavities.
4. Stable performance across wide temperature ranges: ensures stable discharge under both high and low temperatures, prevents battery degradation at low temperatures, generates minimal heat at high temperatures, and effectively suppresses bulging.
5. Five-layer security protection system: Integrated with an intelligent BMS, providing real-time protection against overcharging, overdischarge, excessive current, short circuits, and overheating.
6. High customization compatibility: Size, capacity, output configuration, and protection board can be customized to meet the needs of different device models.
