Samsung SDI has made significant progress in the development of its solid-state batteries, showcasing the latest advancements at SNE Battery Day 2024. The company has delivered initial samples to customers and received positive feedback as it moves towards its goal of mass production by 2027.
At the event held in Seoul, Samsung SDI reaffirmed its goal of achieving an energy density of 900 watt-hours per litre (Wh/L) with its solid-state batteries. Koh Joo-young, Vice President of Samsung SDI, noted, “We have delivered samples to customers from the end of last year to the beginning of this year and have received positive feedback.” The company aims for these batteries to support ranges between 900 to 1,000 kilometres, positioning them in the “super-premium range.”
Samsung SDI began pilot production of its solid-state cells at its Suwon research centre in 2023. While the company initially did not specify a timeline for full-scale production, it has now confirmed that mass production is scheduled to commence in 2027.
The company has set a target of a 40 percent increase in energy density compared to its current prismatic cells. However, Samsung SDI has not yet disclosed target values for gravimetric energy density, which measures energy content relative to weight.
The new solid-state cells are expected to offer enhanced safety features due to the absence of flammable liquid electrolytes. Higher energy density in these batteries can potentially translate into either longer ranges or more compact and cost-effective batteries for the same range.
