Faster charging times will necessitate the need for more powerful charging stations.
According to media reports, Porsche is expecting to be able to produce electric vehicles with 1,300 km of range in the future.
Porsche, which currently uses graphite as an active anode, is said to be developing silicon anodes, which claim to offer up to 10 times more storage capacity and allow its cells to be capable of charging from 5% to 80% in just 15 minutes. However, the company also notes that though the silicon particles can expand by 300% when absorbing lithium, it does impair the service life of the battery. Hence, Porsche is working on anodes with 80% silicon while also trying to increase the proportion of nickel in the cathode – offering higher charging capabilities.
Professor Maximilian Fichtner, head of the Energy Storage Systems research unit at Karlsruhe Institute of Technology, stated that in the medium term, the combination of the new anode chemistry and the dense cell packaging could allow EVs to offer driving ranges of up to 1,300 km (807 miles). Porsche is investing heavily in solid-state batteries, whose researchers claim will have 50% more energy density and reduce charging times significantly.
Reports also state that faster charging times will necessitate the need for more powerful charging stations. Also, the sockets will need active cooling to allow 500 kW charging to be conducted reliably.
