Japan's lithium battery industry got up early but rushed late up

Review of the development history of batteries from lead acid, nickel chromium, nickel metal hydride, ternary lithium battery Japan has always been a global technology leader. As synonymous with high-end batteries. Not only won a high-end share of the global battery market, but also gained huge economic benefits. In recent years, however, Japan has declined in battery development. As if to stop back.

Mottcell new energy analysis to Japan's early great achievements in the battery field, making the Japanese battery enterprises in a state of numbness. In addition, Japan's overall thinking is cautious and conservative, dare not try easily. As a result, the success of the Chinese lithium battery enterprises succeeded, especially the Chinese enterprises led by ternary lithium battery and lithium iron phosphate battery. Technology tends to be mature, high cost performance has been recognized by the global market.

While Chinese battery companies are developing new batteries (sodium batteries, vanadium batteries, graphene batteries, etc.), Japan is obsessed with the research of hydrogen fuel cells. Put a lot of energy, capital, and resources into it. But progress has been slow. It is not directly proportional to the results obtained. Thus delaying the development of lithium battery new track.

In particular, Japan recently said it has developed a new lithium battery: lithium-sulfur battery, claiming to have eight times the energy density of existing lithium batteries. However, professionals have analyzed that sulfur batteries have a fatal disadvantage. Lithium sulfide, the product of battery discharge, will interact with the electrolyte to form a paste of fluid, which looks like the paste used when pasting couplets. The longer the discharge, the thicker the electrolyte, the greater the resistance, the slower the lithium ion movement, and eventually the discharge. So it's still a long way to go. So just leads to the delay can not be put into the market and mass production.

Mottcell new energy: from this see the Japanese lithium battery enterprises began to worry. Panic adjustment strategic panic. If you miss this development opportunity. Over the next few years, along with the global ban on the sale of fuel vehicles and carbon-neutral targets. Japan will have a hard say. After all, energy is the lifeblood and foundation of a country.
