Recently, according to reports from Carscoops, Porsche plans to manufacture electric cars with a range exceeding 807 miles (about 1300 kilometers) in the midterm. Interestingly, these electric cars will be equipped with lithium batteries, not solid-state batteries.So, how will Porsche accomplish this battery technology feat? Carscoops reports suggest that Porsche believes one approach lies in optimizing anode materials.Currently, Porsche is developing silicon anode materials. This development would allow the energy storage density of the battery to be increased tenfold. In addition, it would equip the battery with fast charging capabilities, allowing it to go from 5% to 80% charge within 15 minutes.However, there is a clear problem with this silicon anode material. It can expand by 300% when absorbing lithium, directly affecting the lifespan of the battery. To address this, Porsche is now researching anode materials with as much as 80% silicon content. Simultaneously, they're increasing the nickel content in the cathode materials to achieve a higher charging capacity.In addition, the report also mentions that Porsche is developing advanced solid-state batteries with an energy density 50% higher.

Porsche's Lithium Battery Technology Reserves
A look at Porsche's battery technology arsenal shows that it follows two major paths: high-silicon anode lithium batteries and solid-state batteries. The goal is to achieve high energy density and ultra-fast charging to meet the demand for ultra-high range. However, this raises issues. The higher the range, the greater the weight and cost of the battery. This is a common research and development direction for battery companies and car companies, that is, how to achieve higher ranges without increasing costs and weight.One thing to note is that Porsche is known as the world's most profitable luxury car company. This fact directly means that it can bear relatively high research and development, and manufacturing costs.According to official Porsche data, in the first quarter of 2023, it achieved a business revenue of 10.1 billion euros, an increase of 25.5% year-on-year; a sales profit of 1.84 billion euros, an increase of 25.4% year-on-year; and a net cash flow of 1.43 billion euros from car operations, a significant increase of 83.6% year-on-year.In view of the battery technology roadmap, Porsche has already started making investment arrangements.In the area of high-silicon anode lithium batteries, Porsche participated in the Series C funding round of the US lithium silicon battery developer Group14 Technologies last May. They invested $100 million for the production of silicon anode materials.Data reveals that Group14 was spun off from EnerG2, a company that develops and manufactures carbon materials. In 2019, Group14 conducted a Series A funding round, raising $18 million. The investors included CATL, Showa Denko of Japan, Cabot, and BASF.Currently, Group14 owns two independent factories. One is the first battery material manufacturing factory that started in April 2021, and the other, according to CEO Rick Luebbe, will be built in Eastern Washington State. This second factory will be partly funded by the Series C investment.Porsche has already arranged where Group14's silicon anode materials will go—Group14 will supply products to the Cellforce Group. The Cellforce Group is a joint venture company established by Porsche and Customcells Holding, a German specialty battery manufacturer, in 2021. The company plans to develop and produce high-performance batteries using silicon anodes for small-series production, racing cars, and high-performance vehicles in the future.In terms of solid-state batteries, Volkswagen Group, Porsche's parent company, has been investing in the solid-state battery manufacturer QuantumScape since 2018, becoming its largest shareholder. QuantumScape announced in December 2020 that it had solved the technical problems of solid-state batteries with an energy density exceeding 1000 Wh/L and plans to begin mass production of solid-state batteries between 2024 and 2025. Volkswagen Group plans to use these batteries in its models.
