China’s submarine fleet may soon be powered by lithium batteries​

  • Technical solutions have been found through extensive development and testing in booming electric car market, according to navy study
  • Researchers say that replacing problematic lead-acid batteries with lithium could significantly boost subs’ survival and combat abilities

, according to a Chinese navy study.

A lithium power source – instead of lead-acid batteries – could more than double the time a submarine can spend under water, give it Tesla-style acceleration and create more room for weapons, said researchers with the Naval Submarine Academy in Qingdao, Shandong province.

The changes could significantly boost a submarine’s survival and combat abilities, they said in a paper published in peer-reviewed Chinese journal Marine Electric and Electronic Engineering on October 15.

Surely China has managed to overcome safety issue with Li-Ion ... perhaps like BYD blade battery but with much more advanced version

Interesting what other bans will be impose to Chinese companies? ;) perhaps ban all Chinese EV and CATL and BYD, as it is in a way helping Chinese military according to the idiots there :rolleyes:

Are they trying to say that 039C is not already using LIB? I would be very surprised if that's the case. It would make little sense to wait 4 years to start 039C unless they are using a host of new technology like LIB (most likely LFP), permanent magnet motor and the latest high efficiency power chips. I would say this is the best time to do quick iterations of this technology. LIB energy density, power chip efficiency and electric motor technology in general have increased so much in the past 2 years even.

if they say they're going to use LIB, that means LIB is already deployed.
