These include the first generation of sodium-ion batteries with an energy density of 160 Wh/kg, released in 2021, and the battery with the highest integration efficiency in the world, Qilin, unveiled in 2022.
In their latest announcement, CATL revealed that its newest battery would have an energy density of up to 500 Wh/kg. According to CATL, this battery can achieve a higher energy density and high level of safety at the same in a creative manner. In addition, the battery is also powerful enough to be used in passenger aircraft, which CATL believes will usher in an era of universal electrification of sea, land, and air transportation.
CATL elaborated on the design of the condensed battery by explaining that it features a range of innovative technologies. These include ultra-high energy density cathode materials, innovative anode materials, separators, and manufacturing processes, resulting in excellent charge and discharge performance. In addition, the battery is said to leverage highly conductive biomimetic condensed state electrolytes to construct a micron-level self-adaptive net structure. These can adjust the interactive forces among the chains, which improves the conductive performance of the cells and the efficiency of lithium-ion transporting along with the stability of the microstructure.
CATL believes that its new battery technology will break the limits that have long restricted the battery development sector. While CATL is currently working with partners to use this battery technology for the development of electric passenger aircraft, it will also launch the automotive-grade version of condensed batteries. These are expected to be put into mass production within this year. For more information about CATL and its products, visit the official website (https://www.catl.com/en/).
