2. Innovation • Grid Material: Self-developed seven-element alloy grid with low resistance and corrosion resistance, improving charge acceptance by 2.5 times and extending deep cycle life by 1.3 times. • Curing Process: High-temperature, high-humidity, and pressure-applied process precisely controls the structure of 4BS and 3BS in the active material, alleviating the capacity fading issue of solid-state batteries. • Electrolyte & Formation: Self-developed low-internal resistance, pollution-free solid electrolyte; internal formation adopts a new pulse-based, efficient and environmentally friendly technology.
3. Maturity • Aligns with national "dual carbon" strategy and policy guidelines such as the 14th Five-Year Plan for New Energy Storage Development. • Highly automated manufacturing processes with smooth workflows, suitable for large-scale industrial production.
4. Outstanding Advantages • Features deep cycle charge and discharge, large capacity, non-combustible and explosion-proof properties, solid electrolyte, environmental friendliness, and side-installable use, with a service life far exceeding that of traditional batteries.
III. Main Application Scenarios Widely applicable to the following energy storage fields: • New Energy: Photovoltaic power stations, industrial and commercial energy storage, centralized energy storage stations, residential energy storage, street lamp energy storage • Industry & Transportation: Backup power and energy storage systems for transportation, telecommunications, petroleum, marine, meteorology, and other industries
IV. Operation Instructions
1. Installation Requirements • Environment: Install in a well-ventilated, dry, and clean indoor environment, away from direct sunlight and high-temperature heat sources. The recommended ambient temperature is 15℃~25℃. • Placement: Can be placed upright or on its side; inversion is strictly prohibited. Maintain a spacing of ≥10mm between battery packs for heat dissipation. • Wiring: Securely connect the positive and negative terminals. Use insulated tools to avoid short circuits and electric shock risks.
2. Charging Specifications • Float Use: Recommended charging voltage is 2.27V~2.30V per cell (at 25℃); long-term float charging can extend battery life. • Cycle Use: Charging voltage is 2.40V~2.45V per cell (at 25℃), with an initial charging current not exceeding 0.2C10 (e.g., ≤100A for 500Ah models). • Temperature Compensation: For every 1℃ change in ambient temperature, adjust the charging voltage by approximately -3mV/℃/cell.
3. Discharge & Maintenance • Discharge Current: It is recommended not to exceed 0.3C10. Avoid deep over-discharge (a discharge depth >80% will accelerate life degradation). • Charging Timeliness: The battery must be fully recharged within 24 hours after discharge to prevent plate sulfation. • Regular Inspection: Inspect the battery pack voltage and connection status every 3~6 months. Clean the terminals to prevent oxidation and corrosion. • Prohibited Actions: Short-circuiting, disassembling the battery, or disposing of it in fire or water is strictly prohibited.
V. Safety & Environmental Protection Notes • Built-in safety valve and leak-proof structure, with no acid mist emissions, pollution, or corrosion. • The battery casing is made of flame-retardant material with explosion-proof properties, ensuring safer use. • Waste batteries must be recycled by professional institutions to avoid heavy metal environmental pollution.
Hunan Great Wall New Energy Co., Ltd. has won the First Prize for Scientific and Technological Progress awarded by the All-China Environment Federation (ACEF) for the project: Innovative Development and Application of Key Technologies for High-Energy and Environmentally Friendly Solid-State Lead Batteries.
