Everyone talks about the change from vehicles with internal combustion engines to electric cars… and also about the problems that their autonomy and recharging pose. The advances in recent years are notable… and pay attention to what the Taiwanese battery technology company ProLogium now promises with its 100% silicon anode battery: 300 km of autonomy with a charge of just 5 minutes.
ProLogium assured in the presentation (during the Paris Motor Show) that its new battery system achieves a energy density of 321 Wh/kg. It’s outrageous. To give you an idea, the 53 kWh battery pack of the Hyundai Ioniq 6 has a power of 153 Wh/kg, and the best ones that Tesla mounts have a power of 232.5 Wh/kg.
In addition to energy density (key to having lightweight and therefore more efficient and dynamic electric cars), it seems that this technology also charges incredibly fast: it can go from 5% to 60% in just 5 minutes and can reach 80%. % in 8.5 minutes. We’re missing the (vital) battery pack capacity data, but that would be 80% faster than current EV charging technology. Goodbye to queues at public charging stations and long waiting times while charging on the road.
These batteries also have a modular designwhich should make them easier to repair and recycle… and hopefully reduce the cost of EV ownership.
ProLogium noted that it is also expanding its research and development into the commercialization of its energy solutions. It is partnering with German automotive transmission and technology company FEV to begin manufacturing battery packs in the near future.
Everything seems to indicate that there will be interesting competition in the race to offer batteries for next-generation electric vehicles. Panasonic already has the 4680 cells (light and compact) ready to enter mass production… and that same company joined forces with Sila, based in Washington, to use the latter’s silicon anode technology to increase 25% in the energy density of the battery. We cannot forget solid-state batteries or carbon fiber-based technology that allows the battery to be part of the vehicle structure and its weight does not add to that of the vehicle.
