Samsung SDI plans to achieve its target energy density of 900 Wh/L with its solid-state batteries by utilizing a proprietary solid electrolyte and anode-less technologies. These advancements are crucial for enhancing both the performance and safety of the batteries compared to traditional prismatic batteries.
- Solid Electrolyte Technology: Replacing the liquid electrolyte in traditional lithium-ion batteries with a solid electrolyte increases safety by eliminating the risk of thermal runaway and reducing internal resistance. This allows for higher energy density and efficiency.
- Anode-less Technology: Traditionally, solid-state batteries face challenges with anode materials that can react with the solid electrolyte. By developing an anode-less design, Samsung SDI aims to mitigate these issues, potentially increasing the overall energy density and stability of the battery.
- Mass Production Planning: Samsung SDI is set to begin mass production of these solid-state batteries in 2027, marking a significant step towards commercializing this technology.
By combining these innovative technologies, Samsung SDI aims to increase energy density by 40% over current prismatic batteries, significantly improving electric vehicle range and performance.
