CATL and BYD compete for supercharging, and power batteries will enter the 6C era.
Release time:2024-06-20
CATL plans to launch the second-generation product of Kirin Battery in the second half of the year - a power battery with a charging rate of 6C. At the same time, BYD, which has not released a new battery product for three years, is also considering launching fast charging battery products: sources close to BYD have revealed that BYD's second-generation blade battery may be launched in the second half of this year, and BYD's 6C battery is also under development.
"C" refers to the charging rate. In theory, the power battery supports a "few C" charging rate, which means it can be fully charged within a few minutes of an hour. In the actual charging process, the peak rate is generally used as the standard - the maximum peak rate during the charging process can reach "several C", which is called "several C supercharging".
From the launch of 3C in 2022 to the launch of 4C and 5C in 2023, electric vehicles are now entering the era of 6C. This means that manufacturers not only need to start improving at the level of battery cell materials, but also need to upgrade at the level of battery systems. In terms of materials, fast charging batteries not only need to be paired with fast charging graphite, electrolytes suitable for fast charging, separators and other materials, but also can mix and match basic lithium iron materials with NMC materials to balance performance.
We have currently launched pure iron lithium 6C batteries and are in mass production! Pure iron lithium batteries are relatively safer and more stable, and also have better performance.
