Since the vast majority of electronic products such as digital cameras, mobile phones, and laptops now use lithium batteries, the mainstream batteries of laptops are currently used, and the most commonly used are Li-ion batteries The reason is that Lithium(Li) is more dangerous when used.

Chinese scientists have developed a lithium battery that can be used at minus 70 degrees Celsius and is expected to be used in the extremely cold regions of the earth and even in outer space in the futureStudies published in the latest issue of the American energy academic journal Joule show that the new battery developed by Xiayongyao's team at Fudan University in China uses ethyl acetate, which has a low solidification point and can conduct electricity at extremely low temperatures, as an electrolyte.

Batteries supplied to electric, plug-in and hybrid vehicles increased to 1028 GWh in the first quarter of this year, up 57 percent from a year earlier, according to market research firm SNEResearch.

On the premise of ensuring safety, improving energy density, reducing production cost and improving product consistency are widely concerned topics in the power battery industry The production cost curve is constantly fluctuating, and the consistency of products is not easy to quantify.

According to the "China Securities Daily" report, a person inside the Ministry of Industry and Information Technology recently revealed that the Ministry of Industry and Information Technology is stepping up its research on the introduction of a power battery recycling plan The relevant policies are expected to be issued in 2018.

A team of senior us officials recently visited China to negotiate a trade war with China As a result of the china-us economic and trade consultation, the two sides have reached some consensus in some areas, but there are still big differences on some issues.

Lithium ion battery monomer is composed of positive and negative, electrode, electrolyte and membrane, which is the basic structural unit of battery module and battery pack As a kind of electrochemical power source, battery has the characteristic parameters of voltage, internal resistance, capacity, energy and power.

The core of electric vehicles is batteries The advantages and disadvantages of batteries determine the life of electric vehicles, the speed of weight, and traditional lead-acid batteries have always been the best choice for electric vehicle batteries, but lead-acid batteries are heavy and can occupy 40 % of the entire car.

Lithium-ion batteries are rechargeable batteries that rely mainly on lithium ions to move between positive and negative poles During the charging and discharging process, Li + is embedded and deembedded between the two electrodes: When recharging the battery, Li + is deembedded from the positive electrode, the negative electrode is embedded through the electrolyte, and the negative electrode is in a lithium-rich state; When discharging, it is the opposite.

Lions Technology announced on the evening of March 1 that the company signed the "Investment Agreement" with Yuanzhibin, Chen Huangchunyan, and Yuanzhibin on February 28 The company plans to use its own funds to invest 50 million yuan in joint ventures with Chen Yi, Yuanzhibin, and Huangchunyan.
