CATL unveils condensed battery with an energy density of 500 Wh/kg

CATL has launched condensed battery, cutting-edge battery technology at Auto China in Shanghai. With an energy density of up to 500 Wh/kg, the battery can achieve high energy density and a high level of safety at the same time in a creative manner, opening up a brand-new electrification scenario for passenger aircrafts. CATL can achieve mass production of condensed batteries in a short period of time.

CATL’s condensed battery leverages highly conductive biomimetic condensed state electrolytes to construct a micron-level self-adaptive net structure that can adjust the interactive forces among the chains. This improves the conductive performance of the cells and, in turn, the efficiency of lithium-ion transporting while boosting the stability of the microstructure.

In addition, the 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.

The company says the launch of this cutting-edge technology breaks the limits that have long restricted the development of the battery sector. Also, it will open up a new scenario of electrification cantering with a high level of safety and lightweight. Currently, CATL is cooperating with partners in the development of electric passenger aircrafts and practicing aviation-level standards and testing in accordance with aviation-grade safety and quality requirements.

In addition, the company also plans to launch the automotive-grade version of condensed batteries, which are expected to be put into mass production this year.

CATL has developed the capability to turn fundamental research into industrial applications and then into large-scale commercial applications. In 2021, CATL rolled out the first generation of sodium-ion batteries with an energy density of 160 Wh/kg, which was launched on Chery Automobile during this exhibition. Last June, days after, the company unveiled the Qilin battery with an energy density of 255 Wh/kg, the highest integration efficiency in the world; it started mass production this March.

The launch of condensed batteries will usher in an era of universal electrification of sea, land, and air transportation, open up more possibilities for the development of the industry, and promote the achievement of the global carbon neutrality goals at an earlier date.
