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

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

1. Application of lithium titanate battery in international market At present, lithium titanate is a very special material with technical focus internationally. Toshiba, a major manufacturer of lithium titanate batteries in the world, has put lithium titanate batteries on the market since 2007. At present, lithium titanate batteries have been widely used in small electric vehicles, HEV vehicles and ISS systems. 2. Advantages and disadvantages of lithium titanate Experts at the meeting generally believed th

At present, the power battery industry pattern is undergoing the "three kill" between China, Japan and South Korea. Due to the policy dividend and subsidy advantages in the early stage, China's battery industry has made considerable progress, and China has become the country with the largest power battery shipment in the world. Ningde Times, BYD and others have risen rapidly, and there is little difference with foreign enterprises in technology. But objectively speaking, China's battery industry a
