Although with the development of technology, new batteries continue to emerge, lead-acid batteries will continue to shine in these important areas in the foreseeable future, escorting the stable operation and development of society.

In the energy system of modern society, although lead-acid batteries have been around for a long time, they continue to play an irreplaceable important role in key areas such as communication base stations and emergency power supplies by relying on their own unique advantages.

(1) The cornerstone of stable power supply

The communication base station is like the "lighthouse" of the information age, which needs to operate stably all day long, and any instantaneous power interruption may lead to the interruption of communication services, affecting the range from local areas to large user groups, and the consequences are unimaginable. The lead-acid battery is used as a backup power supply, which bears the heavy responsibility of power supply when the mains power failure. Its working principle is based on the electrochemical reaction of positive and negative plates in sulfuric acid electrolyte, which can be seamlessly switched in the instant of mains failure to provide continuous power supply for base station equipment.

Taking the lead-acid battery pack of a 48V communication base station as an example, it is commonly configured with multiple 12V lead-acid batteries in series. This combination can provide a stable DC output voltage to meet the needs of communication equipment and transmission equipment in the base station. In daily operation, the mains float charge the lead-acid battery pack through the switching power supply to maintain the full state of battery power and supply power to the base station equipment. Once the mains is interrupted, the battery pack is discharged immediately to ensure the normal operation of the base station equipment and ensure the continuity of the communication network.

(2) Adapt to diverse environments

Communication base stations are widely distributed, from the top of the high-rise in the bustling city to the corner of the remote mountain, from the hot and humid tropical rain forest to the dry and cold Gobi desert, environmental conditions vary greatly. Lead-acid batteries have excellent environmental adaptability and can work stably under different temperature and humidity conditions. In a high temperature environment, through reasonable ventilation and cooling measures in the battery room, as well as the selection of high temperature resistant battery materials and electrolyte formula, lead-acid batteries can effectively inhibit the risk of thermal runaway and ensure normal charge and discharge performance. In the low temperature environment, although the battery capacity will be reduced, but by equipped with heating devices or using special low temperature performance of lead-acid batteries, the base station can still meet the backup power needs during the low temperature period.

(3) Significant cost-effectiveness

From the initial construction cost point of view, the price of lead-acid battery is relatively low, compared with other types of backup power supply, in the construction of large-scale communication base stations, can effectively reduce the procurement cost of power system. At the same time, lead-acid battery technology is mature, maintenance is relatively simple, after long-term practice, communication operators have accumulated rich experience in maintenance, which further reduces maintenance costs. Moreover, lead-acid batteries have a high recycling value, scrapped batteries can be dismantled and recycled through professional recycling channels, including lead, sulfuric acid and other raw materials can be recycled to reduce resource waste, from the perspective of the whole life cycle, the cost advantage is more prominent.

2, lead-acid battery in the field of emergency power application interpretation

(1) Power guarantee at critical moments

Emergency power supply is the last line of defense for responding to emergencies and ensuring public safety and the operation of important facilities. Whether it is natural disasters such as earthquakes, floods, or man-made accidents such as large-scale power outages, emergency power needs to be activated quickly to provide power support for key places such as hospitals, transportation hubs, and financial institutions. Lead-acid batteries have become one of the preferred solutions in emergency power systems due to their high reliability and large capacity characteristics.

In the hospital, once the mains power is interrupted, the lead-acid battery-driven emergency power supply should immediately power medical equipment in key areas such as the operating room and the intensive care unit to maintain the normal operation of the life support system and ensure the safety of patients. At transportation hubs, emergency power supplies power signals, elevators, automatic ticketing systems and other equipment to avoid traffic chaos caused by power outages. The lead-acid battery can release a large amount of electricity in a short period of time to meet the high current demand when the emergency equipment is started, and then continue to supply power steadily until the mains is restored or the standby power generation equipment is started.

(2) A variety of types to adapt to different scenarios

There are various types of lead-acid batteries in the field of emergency power supply, including liquid-rich lead-acid batteries, valve-controlled sealed lead-acid batteries (VRLA), and so on. Liquid-rich lead-acid batteries feature large capacity and high discharge rate, and are suitable for scenarios that require large backup power capacity and long power supply duration, such as emergency power supplies in large data centers. Its open structure is convenient for maintenance personnel to check the electrolyte level and density regularly and carry out maintenance operations such as liquid replenishment in time.

Valve-controlled sealed lead-acid batteries, with their maintenance-free and good sealing performance, are widely used in places where installation space is limited and maintenance conditions are harsh, such as emergency power supplies for distributed base stations. This battery in the normal use process, the electrolyte will not leak, no need to regularly add water maintenance, greatly reducing the maintenance workload, improve the reliability of the emergency power system.

(3) Synergy with other energy sources

In some complex emergency power systems, lead-acid batteries do not operate in isolation, but in conjunction with other energy sources such as diesel generators, solar photovoltaic panels, and so on. When the mains is normal, the solar photovoltaic panel converts solar energy into electricity, part of the supply load, and the excess part charges the lead-acid battery to achieve efficient utilization and storage of energy. When the mains power is interrupted and the solar energy is insufficient, the lead-acid battery is first discharged to supply power to the load, and as the battery power drops, the diesel generator automatically starts, on the one hand to supply power to the load, and on the other hand to charge the lead-acid battery, forming a complementary energy supply system. This collaborative mode gives full play to the energy storage characteristics of lead-acid batteries and the power generation advantages of other energy sources, and improves the overall performance of the emergency power system and the ability to cope with complex situations.

Lead-acid batteries have built a solid power guarantee network in the field of communication base stations and emergency power supplies by virtue of their stability, reliability, adaptability to the environment, high cost effectiveness and good coordination with other energy sources. Although with the development of technology, new batteries continue to emerge, lead-acid batteries will continue to shine in these important areas in the foreseeable future, escorting the stable operation and development of society.
