Samsung's Radical New Solid-State Batteries on Sale in 2026

Its long-anticipated 600 mile solid-state batteries (that can charge in 9 minutes) are heading to market in a three-way agreement between itself, BMW, and American battery expert Solid Power.
Samsung's all-solid-state batteries (ASSBs) have an energy density of 500 watt-hours per kilogram, making them twice as dense as conventional lithium-ion batteries. The South Korean company says they are smaller, lighter, and safer than conventional batteries, and are capable of driving 600 miles, and charging within 9 minutes.
Typically, a lithium-ion battery pack in a modern EV charges from 10 percent to 80 percent in around 45 minutes, and has a limit of around 300 miles of range. So, the ASSBs are a radical upgrade to what drivers are currently using.
ASSB cells use solid electrolyte instead of liquid electrolyte found in a lithium-ion battery. They offer superior safety, as they aren’t flammable, and last for 20 years, or 2,000 charge-discharges, equating to 1.2 million miles.
Under the trilateral agreement, Samsung will supply ASSB cells featuring the solid electrolyte developed by Solid Power to the German automotive group BMW, which will then develop modules and packs for ASSB cells to fit into their next-generation evaluation vehicles, expected in late 2026.
Another benefit of Samsung’s ASSBs is that they use a silver-carbon layer as the anode and a nickel-manganese-cobalt material for the cathode. Silver is not only the most electrically conductive metal available, it’s also substantially more plentiful in the Earth’s crust than lithium.
