Samsung has recently unveiled a groundbreaking solid-state battery technology that promises to revolutionize the electric vehicle (EV) market. These new batteries are designed to last up to 20 years, offering an unprecedented lifespan for EV components. However, the high production costs mean that these batteries will initially be available only in “super premium” segments of the market.
A New Era in Battery Technology
During the SNE Battery Day 2024, Samsung SDI announced that its pilot production line for these advanced solid-state batteries is now fully operational. “We established a pilot line last year to begin mass production of solid-state batteries by 2027,” a Samsung SDI representative said, as reported by The Elec. The initial batches of these batteries have been sent to electric vehicle manufacturers for testing, and the feedback has been overwhelmingly positive.
The Promise of Solid-State Batteries
Solid-state batteries stand out for their ability to deliver an impressive range of approximately 965 kilometers (600 miles) on a single charge, recharge in just 9 minutes, and last up to 20 years. Compared to the current lithium-ion batteries, solid-state versions are smaller, lighter, and significantly safer. By replacing liquid components with solid materials, they greatly reduce the risk of leaks and other safety concerns.
Despite these advantages, the high cost of producing solid-state batteries means they will first be adopted in the “super premium” segment of the electric vehicle market. Alongside these, Samsung is also working on high-nickel density (NCS) products for the premium segment.
Doubling the Range of Electric Vehicles
With an energy density of 500 Wh/kg—almost double that of the conventional 270 Wh/kg found in today’s electric vehicles—this technology has the potential to double the range of current EVs. However, the promise of a 9-minute recharge likely refers to charging from 10% or 20% to 80% capacity, a practice commonly used to preserve battery health and longevity.
In addition to solid-state batteries, Samsung is also developing lithium iron phosphate (LFP) and cobalt-free batteries, as well as a dry electrode production method aimed at reducing costs. “We plan to align our prices within the popular and entry-level segments and start mass-producing products that can be quickly recharged in 9 minutes by 2026,” Samsung SDI stated.
Fierce Competition in the Battery Industry
The battery industry is highly competitive, with Chinese manufacturers like CATL also developing long-lasting batteries. Some competitors have already announced semi-solid battery packs with a capacity of 150 kWh, capable of covering over 1,000 kilometers (620 miles) on a single charge. Additionally, while Samsung’s 9-minute recharge claim is impressive, Chinese rivals are already offering even faster charging speeds.
One of the significant challenges that remains is the charging infrastructure, as there are still relatively few fast-charging stations available. Nevertheless, Samsung’s vision of extending battery life to 20 years aligns with market trends, where durability and long-term performance are increasingly valued by consumers.
With these advancements, Samsung is not just keeping pace with the competition but potentially setting a new standard in the electric vehicle market.
