China's lithium battery industry is in the ascendant. Under the encouragement of national policies, the expansion of existing production capacity and the development of potential production capacity have doubled year by year. As the most profitable and valuable separator in the inner layer of lithium-ion battery, it is the first to develop. The main performance requirements of the current lithium battery separator are: thickness uniformity, mechanical properties (including tensile strength and puncture resis

Cobalt is a necessary metal raw material for the manufacture of new batteries. In recent years, with the development of the power vehicle industry, the supply of cobalt, an important raw material for power source ternary batteries, continues to be tight. According to statistics, since the end of 2015, the domestic metal cobalt price has shown a fluctuating upward trend as a whole, with an increase of more than 230%. The recent average price of cobalt has reached 587,800 yuan / ton, and the price has broken through

"The development of new energy vehicles is the only way for my country to move from a big automobile country to a powerful automobile country. It is necessary to increase research and development efforts, carefully study the market, make good use of policies, and develop products that meet various needs, making it a strong rising point. "On May 24, 2014, the ardent expectations put forward by General Secretary Xi Jinping during his inspection of SAIC Motor have become the guide and driving force for the d

What this industry lacks the most is not money, but mature technology and an operation team that can be traded commercially. At present, the industry's concerns about the development of the new energy vehicle industry, in addition to the market-oriented mass production contradiction caused by the promotion and application of the fuel vehicle's own technology and the huge initial cost investment, mainly focus on the relatively mature and commercialized mass production of lithium batteries as kinetic energ

The report shows that the price of some electric vehicle models will be on par with traditional combustion engine vehicles as early as 2024, and will continue to decline in 2025. But for this to happen, battery pack costs need to fall further, even as demand for metals used in battery cells grows. As countries and businesses scramble to tackle urban smog and meet the ambitious climate goals set by the Paris Agreement, calls to promote electric vehicles are growing. In September last year, British MPs called for

In recent years, electronic products such as mobile phones and notebook computers have been developing towards lighter and thinner. Among them, the battery life of the secondary (rechargeable) battery remains the same or smaller, but the battery life is continuously improved. In addition, in the era of new energy vehicles, how to have a longer range of electricity in a limited body space is also a problem that needs to be solved. In order to make the next generation of lithium batteries lighter, the Tianjin Univers

Liu Yanlong, Secretary General of China Chemical and Physical Power Industry Association, said that my country's power battery industry has entered a period of rapid reshuffle. From 2015 to 2017, the number of power battery supporting enterprises has dropped from 150 to about 100, and this process will be further accelerated in the future. . In recent years, as the development of the new energy vehicle industry has entered the fast lane, the power battery industry as its core component has also ushered in a

Cobalt derivatives prices have rarely been stable this week. Entering mid-April, consumer electronics are still in the off-season, and the recovery process of power batteries is slower than expected. The weakness of the terminal finally has a certain inhibitory effect on the skyrocketing upstream. The trading price of cobalt derivatives was flat this week. In terms of lithium salts, SMM believes that there is still some room for decline in lithium carbonate in the second quarter, but the space is limited, mainly be

A research team from Hefei University of Technology has prepared a high-strength, self-supporting, ultra-thin and transparent graphene film and assembled it into an all-solid-state flexible supercapacitor, opening up a new path for the research and development of next-generation flexible electronic devices. The scientific research team of Professor Huai Ping of the school cooperated with the University of Science and Technology of China, Nanjing University, etc., and found the molecule with the strongest interac
