In the Ningde Times, solid -state batteries begin to verify samples, and the energy density of ternary lithium increases exceeding 40%

2024-11-11 19:59:22

Recently, the famous battery manufacturer Ningde Times (CATL) announced that its all -solid battery research and development team has expanded to more than 1,000 people, and officially entered the 20AH sample trial stage this year.

The current sulfide route currently attacked by Ningde Times is considered a key breakthrough point for solid battery technology.According to people familiar with the matter, the scheme of Ningde Times can increase the energy density of the ternary lithium battery to 500WH/KG, an increase of more than 40%compared to the existing battery.However, although the energy density has been significantly improved, the performance indicators such as charging speed and cycle life have not yet reached the expected level, and further research and development and optimization are needed.

The process of trial production of full solid battery samples usually starts with a small capacity sample of 1AH, and gradually increases the battery capacity to verify the battery material, single performance and the feasibility of the overall scheme.In the 1AH sample stage, the main task is to detect the performance of the battery material; and in the 10AH sample stage, the single performance of the battery is subject to the detection of the battery.Entering the 20AH sample stage means that the battery solution has been preliminarily shaped and entered the production technology exploration stage.

Wu Kai, chief scientist of Ningde Times, said at the International Battery Technology Exchange Conference in April this year that the company has built a 10AH full solid -state battery performance verification platform and on positive and negative poles and craftsmanship Technical progress has been made with manufacturing equipment.Nowadays, the Ningde Times has further entered the 20AH trial stage. If the samples at this stage can make breakthroughs in safety and performance, the rest is mainly the manufacturing project problem.

Zeng Yuqun, the chairman of Ningde Times, divided the progress of solid-state batteries into 9 levels, and revealed that the company is currently at level 4. Small batch of all -solid -state batteries.This time line is similar to competitors such as Toyota Motors, LG New Energy, and Samsung SDI, but Zeng Yuqun said at the Power Battery Conference in September this year that the research of Ningde Times was "leading a big step" and rarely announced "Second To None (premier) ".

The solid battery is regarded as the ultimate form of lithium batteries by the industry, and its energy density is far beyond the existing liquid lithium battery.By replacing liquid electrolytes to solid electrolytes, solid -state batteries can not only improve energy density, but also improve the stability and safety of the battery.However, the development of solid -state batteries faces many technical problems, including contact interface problems between positive and negative poles and solid electrolytes, the deposition problem of lithium branches, and the preparation and cost of electrolyte materials.
