With TSMC (2330-TW)(TSM-US) once once more announced that the high-performance computing computer room will be changed to lithium-iron batteries, which also makes the outside world turn to the lithium-iron battery market. The industry believes that lithium-iron batteries have three advantages: safety, stability, cost-effectiveness, energy saving and environmental protection The first choice for industrial solutions.
Nowadays, lithium-ion batteries are roughly divided into ternary lithium batteries and lithium iron phosphate batteries. Among them, ternary lithium batteries are mainly made of nickel (Ni), cobalt (Co), and manganese (Mn) as the main raw materials, which were previously introduced into storage batteries. In the energy market, although it has the characteristics of high energy density, it is not easy to withstand high temperature and has poor safety, so owners have turned to lithium iron phosphate batteries.
The industry admits that due to the high temperature in the computer room, the temperature tolerance of iron-lithium batteries is significantly better than that of ternary batteries. In addition, the charging and discharging process is stable and can also withstand high voltage. Therefore, most of the industry chooses to compromise on energy density and replace it with stability. , Safety and high iron lithium battery.
Furthermore, in the global metal trading market, cobalt is relatively expensive due to its low earth content. Although nickel and manganese are cheaper, the price is still higher than that of iron (Fe). For iron, due to the large amount of earth’s storage, iron is used. The price of the battery made is naturally more affordable.
Today, under the background of the global promotion of green energy, lithium iron batteries are non-toxic and non-polluting, which can effectively reduce environmental impact. In addition, there is no memory effect of the battery itself, and the number of cycles is as high as thousands of times. It has become the UPS of various semiconductor manufacturers. The first choice for uninterruptible power system solutions.
TSMC is optimistic regarding the three advantages of lithium-iron batteries. Following the use of lithium-iron batteries in uninterruptible power systems (UPS), TSMC also announced that it will adjust the power supply structure of high-performance computing computer rooms and use lithium-iron phosphate batteries for DC power supply systems.
