CATL said on the interactive platform today,The company is currently cooperating in the development of civil electric manned aircraft projects, implementing aviation-grade standards and testing, and meeting aviation-grade safety and quality requirements.. The battery used in the field of flight is the "condensed matter battery" launched by CATL in 2023. This is a type of semi-solid battery. Its electrolyte is a gel electrolyte, which has both mechanical stability and ion transport properties.
It uses a high-power bionic condensed matter electrolyte to build a micron-level adaptive network structure, which can adjust the inter-chain interaction force, enhance the stability of the microstructure, improve battery dynamic performance, and improve lithium ion transport efficiency.
The energy density of a single cell can reach up to 500Wh/kg, which is an increase of more than 40% compared to lithium batteries using ternary cathode materials with an energy density of up to 350Wh/kg!
At the same time, because the electrolyte is in a semi-solid colloidal state, its fluidity is reduced, which can avoid the risk of thermal runaway of traditional liquid lithium-ion batteries and significantly improve safety.
It also integrates innovative technologies such as ultra-high specific energy positive electrode, new negative electrode, and isolation film, so that the battery not only has excellent charge and discharge performance, but also has a good cycle life.
It can provide various forms such as soft package and square shape. Among them, the soft package form has the best performance and is not only suitable for electric vehicles but also targeted at the electric aviation market.
