Tesla's new 4680 battery accumulated production of one million battery cells last week. This battery will be a key part in Tesla’s efforts to improve battery life and reduce costs but, in fact, one million battery cells is a drop in the bucket. ...  more

The energy density of commercial lithium-ion batteries has increased again. Recently, American lithium battery company Amprius shipped the first batch of silicon anode lithium-ion batteries, claiming that its battery storage capacity is 75% more than that of the Tesla Model 3 while also lighter and 37% less bulky. ...  more

Swedish Li-ion battery manufacturer Northvolt announced on February 25 that it will be purchasing an old paper mill and its surrounding industrial area from Finnish paper manufacturer Stora Enso and converting it into a gigfactory for cathode active material and battery cells. ...  more

The shadow of the COVID-19 pandemic has made carrying surgical masks a part of daily life but consuming one mask a day also generates an astonishing amount of garbage. ...  more

As Bloomberg reported, a group of Chinese scientists found an extensive lithium source on Mount Everest, possibly containing up to 1.0125 million tons of lithium oxide. ...  more

Rubber is an insulator, and is essentially not an ideal electrolyte material for lithium-ion batteries, though Georgia Institute of Technology has managed to develop a highly conductive rubber material, and the particular flexible electrolyte makes it possible in creating EV batteries that are safer and longer in driving range. ...  more

Swedish-Chinese car maker VOLVO and Swedish Li-ion battery manufacturer Northvolt announced on February 4 that they have selected the Swedish city of Gothenburg as the site of a new jointly-developed gigafactory. ...  more

It is generally understood that rubber is an insulator and, as a result, generally not an ideal material for electrolytes used in li-ion batteries. However, a research team from Georgia Tech has obliterated such a general perception of rubber by coming up with a highly conductive rubber. By leveraging this flexible electrolyte, the team hopes to create a safer EV battery that delivers longer driving ranges. ...  more

Chinese battery manufacturer Gotion High-Tech announced on December 29 last year that construction has begun on its new lithium production complex in Yifeng County in China’s Jiangxi Province. ...  more

Although it has only been heard not seem, scientists continue to note and anticipate the development of lithium-sulfur batteries because their theoretical storage capacity is more than 5 times that of lithium-ion batteries. Now the University of Michigan has developed a new lithium-sulfur battery separation film and believes this design to be "almost perfect" with the number of charges and discharges exceeding a thousand while fast charging. ...  more
