What Batteries Power China Telecom’s Network Infrastructure?
China Telecom’s vast network infrastructure relies primarily on a combination of lithium-ion batteries, valve-regulated lead-acid (VRLA) batteries, and nickel-based batteries to ensure uninterrupted power supply. These batteries provide critical backup during outages, stabilize power fluctuations, and support integration with renewable energy systems, enabling reliable telecom services across urban and rural areas.
What Types of Batteries Are Commonly Used in China Telecom’s Network?
China Telecom employs several battery technologies:
-
Lithium-Ion Batteries: Known for high energy density, rapid charging, long cycle life, and lightweight design, these batteries are increasingly used in urban 5G towers and data centers.
-
Valve-Regulated Lead-Acid (VRLA) Batteries: Widely used in rural base stations and legacy systems due to cost-effectiveness and proven reliability.
-
Nickel-Based Batteries: Used in specific applications requiring robust performance under harsh conditions.
Emerging technologies like solid-state batteries are also being piloted in data centers for enhanced performance.
How Do Lithium-Ion Batteries Support China Telecom’s Operations?
Lithium-ion batteries, especially lithium iron phosphate (LFP) variants, offer corrosion resistance and thermal stability, making them ideal for coastal and extreme weather regions. They reduce physical footprint and maintenance costs while enabling fast recharge cycles. Modular lithium-ion systems scale efficiently with network demands and integrate with smart grid interfaces for energy optimization.
Why Are VRLA Batteries Still Used in Telecom Infrastructure?
VRLA batteries provide a cost-effective, maintenance-free solution with a long history of reliable service. Their sealed design prevents electrolyte leakage, and they perform well in moderate climates. VRLA batteries remain prevalent in rural and less space-constrained sites where initial investment costs are a priority.
Which Emerging Battery Technologies Are Being Tested?
Solid-state batteries with ultra-high energy density and safety features are under pilot deployment in telecom data centers. These batteries promise longer lifespan and improved safety but are currently limited by cost and scalability.
