What is CATL Battery Technology?
CATL, or Contemporary Amperex Technology Co.
Limited, is a Chinese battery manufacturer and technology company that
specializes in the production of lithium-ion batteries for electric vehicles
and energy storage systems1 CATL is the worldĄŻs largest provider of EV
batteries, with a market share of 37% in 2022. CATL has developed several
innovative technologies to improve the performance, safety, and
cost-effectiveness of its batteries. Some of these technologies are:
-
CTP Technology: This stands for cell to pack, which means that the battery cells are directly integrated into the battery pack without using modules or other intermediate components. This increases the volumetric efficiency of the battery pack from 55% to 72%, and enhances the energy density of the battery.
-
CTC Technology: This stands for cell to chassis, which means that the battery cell is integrated with the vehicle body, chassis, electric drive, thermal management, and other modules. This extends the driving range to over 1,000 km, and reduces the power consumption to less than 12 kWh per 100 km.
-
High-nickel Technology: This refers to the use of high-nickel 811 cathode material, which has a higher energy density than other materials. CATL also uses a nano-rivet technology to reinforce and protect the cell structure, and balance the safety and reliability of the battery.
-
High-voltage Technology: This involves the design of single-crystal particles and anti-oxidation electrolytes, which enable higher voltage and more active lithium in the battery. This improves the energy density and lowers the cost of the battery.
-
Long Life Technology: This aims to extend the service life of the battery to 16 years or 2 million km, by using various techniques such as low-lithium consumption anode, passivated cathode, bionic self-repairing electrolyte, microstructural design in electrode sheet, adaptive management of expansive force, and life compensation technology. These techniques reduce the degradation and side reactions of the battery during cycles and storage.
-
Condensed battery: a cutting-edge battery technology at Auto Shanghai. With an energy density of up to 500 Wh/kg, it can achieve high energy density and high level of safety at the same time in a creative manner, opening up a brand-new electrification scenario of passenger aircrafts. CATL can achieve mass production of condensed battery in a short period of time. What is more, condensed battery integrates a range of innovative technologies, including the 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 battery technology is widely used by many automakers around the world, such as Tesla, Volkswagen, BMW, Honda, Toyota, Hyundai, Volvo, Daimler, and others CATL is also expanding its global presence by building manufacturing bases and R&D centers in China, Germany, Japan, France, Canada, and Indonesia CATL is committed to providing high-quality and sustainable battery solutions for the electrification of transportation and energy systems.
