The application of lithium batteries extends to the military field.

March 28, 2019

China, Japan and South Korea, as the three major powers in Asia, have been competing fiercely in many aspects. Recently, South Korea claimed that its lithium-battery submarine is superior to the world's first lithium-battery submarine, the Phoenix Dragon, made in Japan. According to previous Japanese media reports, "Phoenix" may be exported to the Philippines for military applications.

Despite the lack of lithium resources, it is undeniable that Korea is ahead of many countries in the world in the manufacture of lithium battery products.

The proportion of lithium resources in the world

 

South Korea is preparing to build three KSS-3 lithium battery submarines. Last September, the first lithium-ion battery submarine independently developed and manufactured by Samsung, South Korea, was completed. Two other submarines are expected to be manufactured by 2024 and claim to be in real operation by then. Relevant people also said, "Korean companies have the best lithium-ion battery technology in the world..."

 

However, some Russian experts do not think highly of the submarine manufactured by Samsung, South Korea, and think its technical level is not good enough. Although Russia has also made lithium batteries for submarines, the batteries soon failed and could not really be put into use, which shows that Russian experts "disdain" Korean lithium batteries submarine is also justified.

It is understood that traditional lead-acid batteries are the mainstream of submarines used by navies all over the world, but lead-acid batteries can not make further technological breakthroughs and their performance is insufficient. Lithium-ion batteries, as popular batteries nowadays, are safe and reliable. Some developed countries are seeking to develop power systems such as lithium batteries for submarine applications.

 

In addition to lithium-ion submarines, South Korea has been developing a seawater battery in recent years and is expected to commercialize it. It is reported that the R&D team is working to improve the technology of seawater batteries in order to market them in the future. Relevant sources said that sea water batteries will also be used in Military Unmanned submarines and unmanned surface vessels.
