Why is the ternary lithium battery 'out of favor' now?

In the pre-competition, the ternary lithium battery won the final victory due to its long battery life and high density. Tesla also relied on the ternary lithium battery supplied by Panasonic to finally get the market’s approval and its sales were steadily increasing. BYD, which insists on lithium iron phosphate batteries, has just switched to ternary lithium batteries a few years ago. The backward transformation has led to Tesla's overtaking in the market. But when the ternary lithium battery became popular and began to fully occupy the category of pure electric household cars, its harms and disadvantages began to appear. In fact, the biggest problem with ternary lithium batteries is poor safety. The many spontaneous combustion accidents that Tesla broke out in the world in 2019 are known to be related to the unstable characteristics of ternary lithium batteries. In addition, ternary lithium batteries are no longer favored, but also due to cost factors. Regardless of the technology, ternary lithium batteries must use metallic cobalt. With the popularity of ternary lithium batteries, the price of cobalt is getting higher and higher. At the same time, cobalt is also the key to breaking through the process bottleneck of semiconductor chips. With the popularization of 5G communication technology, the price of cobalt has risen again, reaching a maximum of 280,000 yuan/ton this year. The high cobalt has become a burden for new energy car companies. Ternary lithium batteries have poor safety and high cost, which is why Tesla began to pursue cobalt-free batteries, and the most well-known cobalt-free batteries are actually lithium iron phosphate batteries.
