In recent years, building a resource conserving and environment-friendly society has gradually become the consensus of all countries, and the rapid economic development has a huge demand for electricity, making energy storage technology a topic of continuous concern and discussion among governments and industry. Professor level senior engineer from the Institute of Electrical Engineering and New Materials, Chinese Academy of Electric Power Sciences, said that at present, renewable energy has the characteristics

On June 3, 2015, under the guidance of the National Energy Administration and co sponsored by Zhongguancun Energy Storage Industry Technology Alliance (CNESA) and Dusseldorf Exhibition (Shanghai) Co., Ltd., the "Energy Storage International Summit 2015" was held in Beijing. At the sub forum of energy storage technology, Xu Xiaoxiong, a researcher of Ningbo Institute of Materials Technology and Engineering, CAS, delivered a keynote speech. The following is the content of the speech. Xu Xiaoxiong, Resear

The first high-end forum of the China Electric Vehicle Hundred People's Conference with the theme of "new ecology of industrial development" was held in Beijing. At the meeting, Zhang Tianren, Chairman of Tianneng Group, said that the technical route of power battery should be decided by the market. The power battery was first proposed in 1998 in China, which coincided with the two ups and downs of electric bicycles. Since then, Tianneng Group has begun to invest in battery research and development

A few days ago, Toyota Motor (China) Investment Co., Ltd. comprehensively elaborated its determination to accelerate the promotion of the electrification strategy at the electrification technology exchange meeting held in Qingdao. According to the plan, Toyota will launch PHEV plug-in hybrid models on the basis of Corolla dual engine and Leiling dual engine at the beginning of next year, and will first launch C-HR and Yize two EV models in China the year after next. The models promoted in the Chinese market will

Driven by the increasing range of electric vehicles, the use of high nickel materials with higher capacity should be gradually popularized. Generally speaking, high nickel materials can be divided into two categories, one of which is NCA materials (typically LiNi0.80Co0.15Al0.05O2). The Ni content is about 80%. According to the process and material ratio of different manufacturers, the capacity can reach 170-200mAh/g. The second is NCM811 material, whose reversible capacity usually reaches 180-200mAh/g. In recent y

According to foreign media reports, QuantumScape will establish a joint venture with Volkswagen to achieve industrial mass production of solid state batteries. The two sides plan to establish a solid state lithium battery production line in 2025. Nowadays, solid state battery cell is the most promising technology for future electric vehicles. This battery technology can also improve the energy density of current lithium ion batteries, enhance their safety and improve their fast charging capacity. In addition, Vo

Recently, people in the industry found that Tesla (Shanghai) Co., Ltd. has changed its registered capital from 100 million yuan to 4.67 billion yuan, and its business scope has also increased to the manufacture of key components of new energy vehicles such as battery separators, battery management systems, electric vehicle electronic control integration, electric vehicle drive motors, high-power electronic devices, etc. In May this year, Tesla (Shanghai) Co., Ltd. obtained the business license, and TESLAMOTORSHK

According to foreign media reports, GM CEO Mary Barra disclosed on September 5 local time that GM will invest 28 million dollars (about 191 million yuan) to expand its technology center in Warren, Michigan, the United States, in order to create a new testing laboratory and introduce advanced equipment for the battery industry, and achieve the goal of launching 20 electric vehicles by 2023. In the past decade, Warren Technology Center in Michigan has continuously promoted the development of GE's new energy, a

As the saying goes, all martial arts in the world are fast but not broken. In today's efficient society where "time is money", "fast" is the king's way. For a long time, the slow charging speed has been a constraint to the development of new energy vehicles. In order to solve this problem, new energy vehicles have innovated two rapid power supply modes in the electric energy supply scheme: fast charging and power exchange. As the saying goes, literature is not the first, and martial a
