Japan builds lithium battery submarines, why doesn't my country follow suit

In October last year, the Japanese Canglong-class 'Huanglong' submarine was launched into the water. The submarine uses lithium batteries as a power system, replacing the original Stirling engine from Sweden. The 'Huanglong' also became the world's first ship. The submarine using lithium batteries, once the submarine was unveiled, the Japanese people cheered one after another, believing that Japan's submarine technology is leading the world for 20 years.

The electric capacity of lithium batteries is ten times that of ordinary batteries. After replacing the diesel engine, the submarine’s diving time can be increased by 10 days, and the noise can also be well controlled. Just like a new energy car driving on the road. These advantages of lithium batteries are also considered to be the proud capital of the Japanese people.

It stands to reason that my country’s lithium battery technology started in the 1980s and 1990s. After decades of development, it has formed a tripartite trend with Japan and South Korea. Has been widely used, why not learn that Japan will build a lithium battery aircraft carrier?

In fact, the Chinese navy has conducted experiments on the installation of lithium batteries in underwater submarines and mine operations a long time ago, and has achieved success. It can be seen that the navy hopes to use lithium one day The battery is used to power the submarine. But before that, there is still an important issue that needs to be resolved, and Japan has not resolved this issue either.

Although lithium batteries have many benefits, there is a shortcoming that is very fatal. It is really 'fatal'. This shortcoming is that it is easy to catch fire and explode. Lithium battery technology is still immature, new energy vehicles will spontaneously ignite, and submarines that cruise underwater for a long time have a higher risk factor. Once a submarine has an underwater accident, the consequences will be unimaginable. This is also what other countries wait and see for lithium battery submarines. the reason.
