Three battery technologies in the new energy wave

From the current point of view, the development of China's battery has entered the fast lane, mainly due to the rectification of the lead battery industry and the country's initiative to promote new energy, making new batteries springing up like a mushroom, creating a "new energy battery heat" .

High-temperature battery: The backup power supply currently widely used in communication base stations and IDC equipment rooms is an ordinary lead-acid valve-regulated sealed battery. **The temperature is 20°C-25°C, which is very sensitive to high-temperature use environment, that is, long-term environment above 25°C. Use, the battery life will be reduced by half for every 10 °C increase in temperature, so most base stations and IDC rooms need to be equipped with air conditioning, which consumes a lot of energy. Increasing the operating temperature of the battery can not only greatly improve the reliability and safety of the backup battery of the communication base station, but also greatly reduce the energy consumption of the air conditioner caused by the battery cooling, and promote the energy saving and emission reduction of the communication industry in China.

Lithium battery: In the field of communication backup power supply, with the development of the access network and the miniaturization of the communication cabinet, lithium ion batteries with higher weight and volumetric energy are gaining attention and attention from power supply workers in the communication field. A number of foreign communication equipment manufacturers have launched a series of backup lithium-ion battery packs for communication, and large operators have begun to apply successfully.

With the continuous development of technology and the continuous reduction of costs, there will be new technologies to replace lead-acid batteries, so in the future communication power supply field, operators will accept and use lithium iron phosphate batteries on a large scale.

Lithium-ion batteries with higher specific energy have developed rapidly. Lithium-ion batteries with lithium iron phosphate as the positive electrode material have shown good floatation performance, safety, reliability and excellent cycle performance, and will become the communication power source of the future. An important technical type of battery.

However, the cost of lithium-ion batteries is equivalent to 4-5 times that of lead-acid batteries, which restricts the widespread use of the products to a certain extent. Its application direction will be limited to power supply of small-capacity communication equipment such as broadband and access networks for a period of time. Or as a mobile communication power supply.

Fuel cells: Looking at the development of fuel cells for more than 170 years, it can be seen that fuel cells are gradually extending from aerospace, stand-alone power plants to electric vehicle power supplies, portable digital product power supplies, backup power supplies, etc. because of their energy High conversion efficiency (up to 50% or more), good reliability, no pollutants, low noise (<55dBA), continuous operation without the need for charging and other outstanding advantages. In addition, the fuel cell can also be combined with solar power, power supply, battery and other power supply to form a flexible hybrid power supply. At this year's communication show, exhibitors also showed batteries that use hydrogen energy.

The emergence of new batteries has its inevitable reasons. The above three new types of batteries have attracted much attention since their birth. The new batteries have unparalleled performance advantages. However, the new batteries will be new, and many drawbacks have not yet fully demonstrated. For the user, it should be treated with caution in the selection process.
