A milestone breakthrough! --Condensed Battery

2023-04-28

The introduction of CATL's 'Condensed Battery' will greatly promote the further development of battery technology and is expected to be widely used in new energy vehicles, energy storage, aviation and other fields in the future, further enhancing China's position and competitiveness in the global new energy industry, which is a major innovation that has been in the making for a long time, but also a It is a milestone breakthrough that is future-proof and fully meets the all-round requirements of electrification.

With the gradual maturation of lithium-ion battery technology, its energy density is approaching its theoretical limit. This means that the traditional battery upgrade route faces many technical and manufacturing challenges. To meet full electrification and carbon neutrality targets, the industry urgently needs more advanced electrochemical material systems to achieve breakthroughs in higher energy densities. Of course, higher energy densities also mean greater risks and challenges, such as higher demands on battery safety. Therefore, the search for more advanced electrochemical material systems is the core crux of battery technology to achieve new breakthroughs. This new condensed battery is an innovation using solid-state battery technology, the core technology of which is the design and manufacture of condensed electrolytes.

Traditional lithium-ion batteries use liquid electrolytes, which are flawed by the need to withstand extreme operating conditions such as high temperature and pressure and violent impacts within a short period of time, easily causing safety problems such as leakage and combustion. The condensed electrolyte, on the other hand, is a new type of electrolyte developed by CATL - high power bionic condensed electrolyte, which is a combination of various functional materials, with a combination of organic and inorganic materials, organic surface coating covered with inorganic raw materials, thus forming a fast ion conduction condensed electrolyte, which is non-flammable, zero volatile and This significantly improves the thermal stability of the battery, while regulating inter-chain interactions through the construction of a micron-level adaptive mesh structure, which enhances microstructural stability while improving battery kinetics and lithium ion transport efficiency. This condensed electrolyte produces a battery with the advantages of good safety, high energy density and low self-discharge rate. Specifically, it is safer in that the internal material is in a solid polymer and there is no liquid electrolyte that is prone to leakage. Secondly, the current of a condensed battery is more stable, its self-discharge rate is low, and its service life is longer, with higher energy density and better environmental adaptability."

Future industrial innovation must collaborate across borders, break boundaries and develop comprehensively. CATL's condensed batteries are its latest innovation and an important milestone in its zero-carbon strategy, driving the next round of innovation. This innovation is not limited to one segment, but spans the entire industry and drives overall innovation.
