CATL launches high-density battery for Aircraft Electrification at Auto Shanghai

In a major development in the battery technology sector, CATL has launched a groundbreaking battery technology called condensed battery at the Auto Shanghai event. With an impressive energy density of up to 500 Wh/kg, this new technology has the potential to revolutionize the electrification of passenger aircraft.

The unique aspect of condensed battery lies in its ability to achieve high energy density and high levels of safety simultaneously, a feat that has been difficult to accomplish in the past. To achieve this, CATL has leveraged highly conductive biomimetic condensed state electrolytes to construct a self-adaptive net structure that can adjust the interactive forces among the chains, resulting in improved conductive performance of the cells and increased efficiency of lithium-ion transporting.

In addition, condensed battery integrates a range of innovative technologies, including ultra-high energy density cathode materials, innovative anode materials, separators, and manufacturing processes, offering excellent charge and discharge performance as well as good safety performance.

CATL has also confirmed that they are currently working with partners in the development of electric passenger aircraft and are practicing aviation-level standards and testing in accordance with aviation-grade safety and quality requirements.

The launch of this cutting-edge technology breaks the limits that have long restricted the development of the battery sector and will open up a new scenario of electrification centering on high levels of safety and light weight. In addition to the passenger aircraft sector, the condensed battery technology is also expected to be put into mass production for automotive-grade batteries within this year.

“Meeting customers’ requirements is the core driving force that drives technological innovation for CATL,” said Wu Kai, chief scientist of CATL. Currently CATL has the world’s most extensive technology roadmap for batteries, and has developed the capability to turn fundamental research to industrial application, and then to large-scale commercial applications. For example, in 2021, CATL rolled out the first generation of sodium-ion battery with an energy density of 160 Wh/kg, which has been launched on Chery Automobile during this exhibition. In 2022, CATL unveiled Qilin battery with the highest integration efficiency in the world, and it has started mass production this March. They have been used on multiple high-end BEVs such as ZEEKR, AITO and Li Auto.
