Samsung recently demonstrated its breakthroughs in solid-state battery technology, which had a big impact on the EV battery market. In Seoul, South Korea, at the SNE Battery Day 2024 event, Samsung unveiled their fully functional pilot solid-state battery production line. This is a significant step toward mass production, which is anticipated to begin in 2027.
According to Samsung SDI, as cited by The Elec, “We built a pilot line last year to mass-produce all-solid-state batteries by 2027.” Positive feedback has been received from EV manufacturers who have already received the first batches of these batteries for testing.
These cutting-edge batteries have a 20-year lifespan, a 600-mile range, and a quick 9-minute charge time. The EV market could undergo a radical change thanks to solid-state batteries, which are safer, lighter, and more compact than lithium-ion batteries now in use. The use of all-solid-state batteries can improve safety by substituting solid parts for liquid ones. They take up less space and weigh less when used in the same pack size as current items, according to Samsung.
Initially, due to high production costs, these batteries will be limited to the “super premium” EV segment, offering a 600-mile range per charge. Samsung will also introduce high-nickel NCS products for the premium segment. Their oxide solid-state battery technology boasts an energy density of 500 Wh/kg, nearly double the 270 Wh/kg density of mainstream EV batteries, potentially doubling the driving range of current electric vehicles.
Samsung’s claim of a 9-minute charge likely refers to charging from 10% or 20% to 80% capacity, a common industry practice to protect battery health. Additionally, Samsung is developing more affordable lithium iron phosphate (LFP) and cobalt-free batteries, and a dry electrode production method to reduce costs. “We will not only match the price in the popular and entry-level segments, but also mass-produce products that can be rapidly charged in 9 minutes by 2026,” emphasized Samsung SDI.
However, the limited availability of charging infrastructure remains a significant hurdle. While some Chinese battery makers offer 5C or 6C charging speeds, equivalent to 480kW and even 600kW charging stations, they are currently limited in number.
Samsung’s vision to extend battery life to 20 years aligns with broader market trends. CATL and other manufacturers have already announced batteries with similar lifespans, often referred to as “million-mile” batteries. While Samsung’s progress is significant, the company must navigate a competitive landscape dominated by Chinese manufacturers.
