BiCar News Recently, Porsche announced that it had invested US$100 million in Group14 Technologies, a manufacturer of advanced silicon-carbon technology for lithium batteries. Porsche plans to use this technology in its high-performance cars.
“Batteries are at the heart of the future and our goal is to become the leading company in the world’s fiercest battery competition,” said Porsche CFO Lutz Meschke. The investment is part of the Washington-based company’s Series C funding round. Group14 has secured $400 million in funding to build another factory in the United States to produce active battery materials.
Group14 has developed battery chemistry that uses silicon as the negative electrode material. This significantly increases the power density of the battery compared to existing batteries,thus allowing greater autonomy. The technology also reduces the internal resistance of the battery, meaning it can be charged faster than current batteries.
Markus Gräf, Cellforce Group Operations Director, said: “Group14’s anode materials have the potential to be a game-changer in reducing charging times.
The Group 14 said in a statement. from Porsche The products will be supplied to Cellforce Group, a joint venture established in 2021 between Porsche and Customcells Holding, which plans to develop and produce high-performance cells using these silicon anodes for small-batch production, racing and high-performance vehicles. performance. /p>
Michael Steiner, head of Porsche R&D, said: “The fast charging, high performance and low weight chemistry of this new battery will directly bring benefits to the Porsche brand. " They correspondto our ambitions for the development of electric sports cars in the future. “In addition to investing in electric vehicles, Porsche is also investing in e-fuels to adapt to a greener future.

The 4680 batteryis special developed battery.
The 680 battery refers to the new Panasonic brand Tesla series battery, called 4680 battery. The ternary polymer lithium battery uses lithium as the positive electrode material. The nickel-cobalt-manganese or lithium-nickel-cobalt aluminate lithium battery is 5 times larger than 21700. According to the category. situation from 18650 to21700, the capacity is increased by 5 times without taking into account other technical improvements. So it's normal. when it is said that the energy is increased by five times (ENERGY5X), it may actually be about 5 times
The appearance of the 4680 battery looks like one.Tall and fat man. Raw silicon anode material Tesla selects raw silicon material with good energy storage effect, re-develops the battery cell anode, and adds elastic ionic polymer coating to stabilize the silicon surface structure and improve the stability and safety of the battery core.
