A small-scale communication base station communication antenna with an average power of 2 kW can consume up to 48 kWh per day. 4,5,6 Therefore, the low-carbon upgrade of communication base stations and systems is at the core of the telecommunications industry’s energy use issues.
Base stations are important in the cellular communication as it facilitate seamless communication between mobile devices and the network communication. The demand for efficient data transmission are increased as we are advancing towards new technologies such as 5G and other data intensive applications.
The upgrade costs include the base station equipment upgrade and platform construction (detailed cost breakdown in Table S8), totaling an estimated cost of 195.450 billion renminbi (RMB) to upgrade all communication base stations nationwide (detailed information by province in Table S9).
Our findings revealed that the nationwide electricity consumption would reduce to 54,101.60 GWh due to the operation of communication base stations (95% CI: 53,492.10–54,725.35 GWh) (Figure 2 C), marking a reduction of 35.23% compared with the original consumption. We also predicted the reduction of pollutant emissions after the upgrade.

With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
Liquid cooling, due to its high thermal conductivity, is widely used in battery thermal management systems. This paper first introduces thermal management of lithium-ion batteries and liquid-cooled BTMS.
The lithium-ion battery thermal management system proposed by Al-Zareer et al.119 employs boiling liquid propane to remove the heat generated by the battery, while propane vapor is used to cool parts of the battery not covered by liquid propane.
The media such as liquid, phase change material, metal and air play a significant role in battery cooling systems. [5, 18, 19] As the metal media, micro heat pipe array (MHPA) is commonly used in the lithium-ion battery cooling method due to the characteristics of compactness, and the MHPA can enhance the stability and safety of battery pack.
