Chinese battery giant CATL has unveiled a new lithium iron phosphate (LFP) battery that promises 1,000 kilometres of range and 4C super-charging capability.
The so-called Shenxing Plus product was released on the first day of the 2024 Beijing International Automotive Exhibition, 25 April. The battery has an energy density of 205 watt-hours/kilogram and could have 600 km of range added with a 10-minute charge.
CATL also announced it will partner with several charging companies to jointly construct ultra-charging networks, which is expected to greatly accelerate the progress of the industry’s supercharging iteration.
Kallanish learns the new product uses particle grading technology in the cathode to place each nanoparticle in the appropriate position to achieve ultra-high compaction density. It also features three-dimensional honeycomb-shaped materials to the anode to increase the energy density of the anode and effectively control the volume expansion during charging and discharging.
At the same time, in terms of battery cell structure design, CATL has developed the industry’s first integrated shell structure. This improves the space utilisation inside the cell and allows the energy density of the cell to reach a new record high. In addition, by expanding the over-current area and over-current capacity of the pole, CATL has ensured that the temperature can be quickly cooled down even during high-current charging.
This battery uses fast ion conductor coating, transition metal doping, new nano-coating and other technologies to make energy transmission between cathode and anode materials easier and more efficient.
EVs equipped with Shenxing will have access to an exclusive owners club that will be launched in China, offering services such as road rescue, battery testing and maintenance. Further details are yet to be revealed.
