Given the current high production costs, the initial adoption of these batteries will be confined to the “super premium” EV segment.
Samsung recently made a splash in the industry by showcasing its recent advancements in battery technology, especially related to solid-state batteries.
At the SNE Battery Day 2024 expo in Seoul, South Korea, the company revealed that its pilot solid-state battery production line is now fully operational.
"We built a pilot line last year to mass-produce all-solid-state batteries by 2027," said Samsung SDI, as reported by The Elec.
Moreover, the battery’s initial batches have already been delivered to EV manufacturers for testing.
"We supplied samples to customers from the end of last year to the beginning of this year and are receiving positive feedback," Samsung SDI stated.
Notably, these batteries could power electric vehicles with a 600-mile range, charge in 9 minutes, and have a lifespan of 20 years.
These solid-state batteries are expected to be smaller, lighter, and safer than the lithium-ion batteries currently used in most electric vehicles. They hold significant potential to revolutionize the EV industry.
"All-solid-state batteries can enhance safety by replacing liquid components with solid ones. When used in the same pack size as existing products, they reduce weight and take up less space," highlighted the company.
However, due to their high production costs, these batteries'' initial application will be limited to the “super premium” EV segment.
The "super premium" segment here implies a driving range of around 600 miles per charge. In addition, Samsung will be introducing high-nickel NCS products for the premium segment.
Samsung’s oxide solid-state battery technology boasts an energy density of 500 Wh/kg, nearly double the 270 Wh/kg density of mainstream EV batteries.
This increased density could potentially double the driving range of current electric vehicles.
Besides, Samsung’s claim of 9-minute charging likely refers to the standard metric of charging a battery from 10% or 20% to 80% capacity rather than a full charge from 0% to 100%.
This practice is common in the industry as charging speeds typically slow down significantly beyond the 80% mark to protect battery health and longevity.
In addition to its work on solid-state batteries, Samsung is developing more affordable lithium iron phosphate (LFP) and cobalt-free batteries, as well as 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.
That said, limited availability of charging infrastructure remains a significant hurdle. While some Chinese battery makers already offer 5C or 6C charging speeds, equivalent to 480kW and even 600kW charging stations, they are quite few in numbers.
However, notable is the visible approach of all battery makers to offer longer lifespans of batteries. CATL and other battery makers have already announced batteries with 20-year lifespans, often referred to as “million-mile” batteries. Samsung''s vision to "extend the battery life to 20 years" aligns with the broader market trend.
While Samsung’s solid-state battery progress is significant, the company must navigate a competitive landscape dominated by Chinese manufacturers.
The lithium-ion battery is an electrochemical wunderkind. We use it for everything, whether it''s mundane gadgetry like phones and laptops or more extreme applications like electric ships and helicopters on Mars. The Li-ion battery is so important to modern life that it earned the trio of chemists who invented it a Nobel Prize last year. But somewhere along the way, the battery industry developed a cobalt dependency.

Samsung''s oxide solid-state batteries, now in pilot production and testing with automakers, boast an impressive energy density of around 500 Wh/kg – roughly double that of today''s mainstream EV batteries. The Elec notes the batteries have an unbelievably quick time to full-charge of just nine minutes and lifespans up to an incredible 20 years.
According to Samsung SDI Vice President Ko Joo-young, carmakers are going gaga over these next-gen batteries because they are significantly smaller, lighter, and much safer than today''s EV batteries. However, the high production costs mean they''ll initially be confined to the "super premium" EV segment. Luxury electric cars using the tech can travel between 900-1,000 kilometers (over 600 miles) on a single charge without significantly increasing battery size and weight.
Toyota has also circled 2027 as its target for mass producing long-lasting solid-state batteries. However, the carmaker cautioned that its first deployment would likely be limited to premium Lexus EVs.

Samsung has announced a significant breakthrough in electric vehicle (EV) battery technology, introducing solid-state batteries that can potentially revolutionise the EV market. The new batteries promise a range of up to 600 miles on a single charge, with the capability to recharge in just nine minutes. Additionally, these batteries are designed to last up to 20 years, which is a significant advancement over current battery technologies.
The newly developed solid-state batteries by Samsung boast an energy density of 500 Wh/kg, nearly double the capacity of conventional EV batteries, which average around 270 Wh/kg. This increased energy density could substantially extend the driving range of electric vehicles, making them more practical for longer journeys and reducing the frequency of recharging.
