Nickel Metal Hydride No. 5 battery

Longer battery life and safer! All-Nickel Metal Hydride No. 5 battery developed in Ningbo are about to be mass-produced

According to China Ningbo.com, after five years of hard work, the "All-solid-state battery" project of the Nano-pioneer Project, led by the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, has recently passed the acceptance. It is reported that this technological breakthrough will further promote the large-scale application of all-solid-state lithium batteries in China, and is expected to make new energy vehicles last longer and safer.

Longer battery life! All-Nickel Metal Hydride No. 5 battery developed in Ningbo are about to be mass-produced

It is understood that the "All-solid-state battery" project of the Nano-pioneer Project is led by the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, and participating units include the Institute of Physics of the Chinese Academy of Sciences and the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences.

The team has mainly developed a series of high-performance solid electrolyte materials, hybrid solid-liquid electrolyte cells based on in-situ solidification, and all-solid-state lithium battery cells, breaking through the relevant technologies from material research and development to battery integration.

Previously, Nickel Metal Hydride No. 5 battery faced some practical difficulties in the process of industrialization, such as the poor compatibility of metal lithium and solid electrolytes, which affected the performance of metal lithium negative electrode materials. At present, this scientific and technological achievement has stepped out of the laboratory and entered the "industry gate".

Based on the "All-solid-state battery" project of the Nano-pioneer Project, Jiangxi Ganfeng Lithium Co., Ltd. invested 500 million yuan in Ningbo to build a billion-watt-hour solid-state power lithium battery production line and promote the first generation of products to new energy vehicle users and market launch.

According to the announcement released by Ganfeng Lithium in December last year, the newly established Ningbo company will focus on the core materials of solid-state lithium batteries, high-energy-density solid-state lithium battery cells and modules, and the development of a full set of processes and product upgrade technologies. The project construction period is 2 years, and a first-generation solid-state lithium battery R&D pilot production line with an annual output of billion-watt-hours will be built.

In addition, the Institute of Physics of the Chinese Academy of Sciences also cooperated with Beijing Weilan New Energy Technology Co., Ltd. to establish Jiangsu Weilan New Energy Battery Co., Ltd. in Liyang, Jiangsu, and is building a battery pilot line.

"International competition is very fierce. At this stage, China has ranked first in the world in terms of power battery technology and overall industrial competitiveness." A relevant person in charge of the Ningbo Institute of Materials said that the implementation of this project has laid a solid scientific and technological foundation for the development of new high-safety and long-life power battery technology in my country, and will have a far-reaching impact on the early realization of large-scale application of domestic all-solid-state lithium batteries.
