Samsung SDI will showcase its roadmap for mass production of the industry’s highest energy density all-solid-state batteries along with ultra-fast charging and long lifespan battery technologies at the upcoming Interbattery 2024 event.
Starting from Wednesday, June 6, Samsung SDI will participate in the three-day Interbattery 2024 at COEX in Seoul, cementing its leadership in solid-state batteries and unveiling a diverse product lineup to lead the battery market based on its ‘super gap technology’ on June 5.
At this exhibition, Samsung SDI will publicly reveal its roadmap for the mass production of the 900Wh/L All Solid Battery (ASB), boasting the highest energy density in the industry.
The ASB, often referred to as the ‘dream battery’, uses solid electrolytes to reduce the risk of fire while providing longer driving ranges, drawing attention as a next-generation battery in the industry.
Samsung SDI plans to announce its development and mass production plans for the all-solid-state battery, which has an energy density improved by approximately 40% compared to its current prismatic batteries (P5) with a target of 900Wh/L. By enhancing the solid electrolyte materials and implementing innovative anode-less technology, the plan aims to achieve the industry’s highest energy density by reducing anode volume and adding more cathode materials.
Centered around the newly established ASB commercialization team created at the end of last year, Samsung SDI is advancing the commercialization of all-solid-state batteries, producing samples in the S-line of the SDI Research Institute. The exhibition will show a detailed roadmap that assures the uninterrupted progress of mass production by 2027 for the all-solid-state battery.
Moreover, Samsung SDI will introduce ultra-fast charging technology capable of charging cells from 8% to 80% in just 9 minutes, marking a first in the industry.
This ultra-fast charging technology optimizes the lithium-ion migration pathway and reduces resistance, aiming for mass production by 2026. It is expected to significantly decrease charging times compared to existing P5 batteries.
Additionally, plans for the mass production of ultra-long lifespan batteries, designed to last 20 years, are set to be unveiled in 2029, with plans to double the battery lifespan through enhanced material durability.
Alongside these developments, Samsung SDI will present a new prismatic battery form factor and module-less CTP (Cell to Pack) technology that improves energy efficiency and cooling systems by relocating battery terminals. CTP technology reduces components by over 35% and weight by 20%, enabling high energy density and significant cost reductions within the same volume.
Samsung SDI will also introduce thermal diffusion prevention technology, which quickly vents high heat and gases in the event of fire or impact, leveraging the advantages of prismatic batteries to minimize thermal propagation between batteries.
In addition to these offerings, Samsung SDI will showcase a diverse range of battery materials, including high-nickel NCA 46P, mid-nickel NMX, and LFP, expanding its portfolio from premium electric vehicle batteries to more affordable options.
This year, Samsung SDI’s flagship ESS product, the Samsung Battery Box (SBB), won the ‘ESS Excellence Innovation Award’ at the newly established Interbattery 2024 Awards. The SBB features easy installation and improved safety due to the application of direct injection systems, earning recognition in the U.S. and European markets.
Samsung SDI will also make available a space for showcasing small batteries, including high-output cylindrical batteries used in power tools, gardening tools, and cordless vacuums, as well as pouch batteries for IT devices like the Galaxy S24 and wearable batteries.
In the ESG space, Samsung SDI will introduce activities that demonstrate its practice of ESG management as a global battery enterprise. Products certified for their carbon footprint will be displayed alongside the company’s history of publishing sustainability reports as the first domestic company in 2003, its inclusion in the Dow Jones Sustainability Index (DJSI), plans for implementing the RE100 initiative by 2025, and information related to battery recycling.
CEO Choi Yoon-ho states, “Samsung SDI is diligently preparing for the mass production of next-generation products in various form factors, including all-solid-state batteries, and will continue to lead the global battery market through our superior technological expertise.” He further mentions, “This exhibition will showcase Samsung SDI’s differentiated technological prowess and efforts to realize an eco-friendly future society.”
