On 17 August 2020, the Shenzhen Municipal Government announced that Shenzhen has built over 46,000 5G base stations to achieve full coverage of 5G infrastructure in the city. This marks that Shenzhen has become the first city in the country with full coverage of 5G independent group network and the world’s first in 5G base station density. The battery pack is an important part of the communication base station to achieve uninterrupted power supply for the DC system, and the lead-acid battery shell plays the role of protector. What is the material of the lead-acid battery shell for 5G base stations?
It is understood that the general lead-acid battery shell commonly used ABS, PP, PE and other materials, while the medium and high-grade valve-controlled sealed battery is generally used ABS, non-valve-controlled battery is generally used PP, PE, etc. 5G base station with lead-acid battery shell material with Qingdao Zhongxin Huamei flame retardant ABS.

①has high flame retardant efficiency and can give the composite material good self-extinguishing or flame retardant properties, meeting UL94 standards.
(ii) has good heat resistance, and is not easily bulged at high temperatures when injection moulded into the shell.
③Good fluidity, not easy to appear silver lines or air marks in injection moulding, good dimensional stability and good air tightness.
④Good impact resistance, low temperature environment by the impact does not crack.
⑤ Special design of the formula, good heat seal and glue seal effect.
⑥The material does not contain cadmium, chromium and other harmful toxic heavy metals, the production and application process will not cause any pollution to the environment, in line with ROHS certification requirements.
At present, Shenzhen is carrying out demonstrations of government applications in 10 areas such as healthcare and transportation, and in 10 industry areas such as ultra-high definition video and industrial internet. 5G base stations are the core equipment of 5G networks, providing wireless coverage and realizing wireless signal transmission between wired communication networks and wireless terminals.
