Technical Definition

Power lithium battery is a rechargeable energy storage solution that relies on lithium ion intercalation and deintercalation between cathode and anode materials to deliver stable, high-efficiency power output, built for high-demand industrial and mobility applications. As a core component of the new energy manufacturing sector, it is an indispensable technical support for power system upgrade, energy storage deployment and portable power innovation.

To meet diverse industrial and operational requirements, the product line covers two core series, with fully customizable options for special scenarios:
1. Ternary lithium ion battery series: Positioned for high energy density requirements, suitable for power tools, consumer electronics and light electric vehicles, with core features of lightweight design and fast charge capability.
2. Lithium iron phosphate battery series: Positioned for high safety and long cycle life requirements, suitable for energy storage systems, low-speed electric vehicles and sightseeing vehicles, with core features of high thermal stability and low self-discharge rate.

The product line is designed with core principles of high reliability, long service life, easy integration and flexible customization, fully accounting for harsh industrial operating conditions and following full lifecycle reliability design standards to deliver stable, low-maintenance and cost-effective solutions for clients.

Working Principle

The core working principle of the power lithium battery is based on the reversible intercalation and deintercalation of lithium ions between cathode and anode materials. The complete operational logic follows two key phases:
1. Charging phase: Lithium ions are extracted from the cathode material, pass through the electrolyte and separator, and embedded into the anode graphite material.
2. Discharging phase: Lithium ions are extracted from the anode material, returned to the cathode, and release electrical energy to drive connected loads.

Based on this principle, the system architecture adopts a modular design to optimize performance, stability and scenario adaptability, with two core innovative modules:
1. Autonomous cell production module: Equipped with automated spot welding, sticker and capacity grading equipment, controlling cell consistency deviation within ±2% to improve overall battery group performance.
2. Intelligent BMS management system: Real-time monitoring of voltage, current and temperature, with multi-layer protection against overcharge, over-discharge, short circuit and abnormal temperature to extend service life.

Compared to traditional lead-acid battery solutions, the power lithium battery delivers 2-5 times longer cycle life, 60% lower weight and higher energy density, addressing the pain points of low efficiency and high maintenance costs of traditional options. Compared to generic off-the-shelf lithium batteries, the solution supports full specification customization to match diverse application requirements.

Technical Parameters and Specifications

All parameters are tested in strict accordance with international test standards, with clear test conditions and tight tolerance control. Full parameter test reports are available for each batch, with support for third-party authoritative testing.

Note: The above parameters are standard specifications for regular series. Customized parameters and function adjustments are available to meet special operating conditions and application requirements.

Core Technical Advantages

Compared to conventional power lithium battery solutions in the global market, the product line has formed verified competitive advantages through independent R&D and technological innovation:
1. High safety and compliance: Supported by stable LiFePO4 cathode material, multi-layer BMS protection and multiple international certifications, the thermal runaway trigger temperature reaches ≥270℃, with no fire or explosion during overcharge and short circuit tests. This reduces equipment safety accident risks, meets global market access requirements, and improves end-user trust in terminal products.
2. Long cycle life and low total cost of ownership: Supported by autonomous cell screening process and digital closed-loop production, the cycle life reaches ≥2000-5000 cycles, 2-5 times that of traditional lead-acid batteries. This reduces battery replacement frequency, lowers long-term operation costs, and improves overall equipment cost-effectiveness.
3. Flexible customization capability: Supported by fully automated production lines and end-to-end OEM/ODM services, the solution can be customized for voltage ranges of 3.2V-800V and capacity ranges of 500mAh-500Ah or above. This adapts to special equipment requirements, shortens client product development cycles, and improves product differentiation competitiveness.

International Standards and Compliance

All R&D, design, production and testing processes strictly follow the latest international standards and industry specifications, with a complete compliance and certification system to meet the strict procurement and regulatory access requirements of global clients. The product line fully complies with core international standards including IEC 62133 (safety requirements for portable sealed secondary cells), UN 38.3 (UN dangerous goods transport test standard), CE (EU electromagnetic compatibility and safety standard) and UL 1642 (US lithium battery safety standard). It holds product certifications including UL, FCC, CE, RoHS, UN38.3, MSDS, UKCA and CB, with environmental compliance to EU RoHS and REACH requirements. Full supporting documents including third-party test reports, factory inspection reports and declarations of conformity are available for client compliance audits.
