The lithium-ion batteries that we rely on in our phones, laptops and electric cars have a liquid electrolyte, through which ions flow in one direction to charge the battery and the other direction when it is being drained. Solid-state batteries, as the name suggests, replace this liquid with a solid material.
The solid state battery market is poised for growth as companies work to overcome technical challenges. With increased investment and advancements in materials science, solid state batteries may soon play a crucial role in the next generation of energy storage solutions.
In November 2023, Solid Power announced that it had produced the first batch of solid-state battery A samples and delivered them to BMW, and according to the schedule, Solid Power will achieve mass production of all-solid-state batteries by 2030.
"By bringing together the material development technologies of both companies, Idemitsu's material manufacturing technology, and Toyota's battery mass production technology, we will engage in full-scale mass production of all-solid-state batteries," Toyota CEO Koji Sato told a news conference.
In May this year, SAIC Motor publicly announced that its all-solid-state battery (based on the polymer-inorganic composite electrolyte technology route) will be mass-produced in 2026, with an energy density of more than 400Wh/kg.
Recent breakthroughs highlight significant advancements in solid-state battery technology. QuantumScape recently demonstrated a solid-state battery cell that achieved 80% charging capacity in under 15 minutes while maintaining high energy density.
