While lithium-ion is the chemistry of choice for EV batteries, almost every ICE vehicle made today still uses the ancient lead-acid battery technology for its 12-Volt starter battery (Porsche and a couple of other makers of high-performance cars offer lithium-ion starter batteries).
Auto OEMs and battery providers want to preserve the leaded status quo. In fact, lead-acid starter batteries are â€œessential for the needs of future generations,â€ at least according to theInternational Lead AssociationÂ (viaÂ Green Car Reports).
EU regulators are considering new rules that would ban the use of lead in vehicles, but the European automakersâ€™ association ACEA, together with Japanese and Korean trade groups, has submitted a request to extend the existing exemption for lead-acid batteries for another eight years.
In its submission, the group cited a study that found no viable alternatives to lead-acid batteries for starting vehicles in cold climates. The study also noted that 99 percent of lead-acid batteries in EU countries are recycled.
