Differences between solid-state ion batteries and energy storage batteries

What is the difference between a lithium ion and a solid state battery?

Solid-State Battery: These can pack up to twice as much energy as lithium-ion batteries, especially when replacing the anode with a smaller alternative. Lithium-Ion Battery: These have lower energy density compared to solid-state batteries. Solid-State Battery: Their solid electrolytes are less reactive, leading to longer lifespans.

What are the advantages of a solid state battery?

High energy density: Solid-state batteries can achieve energy densities of 500Wh/kg or even higher, making them suitable for future electric vehicles and other high-energy demand scenarios. Longer cycle life: Solid-state batteries exhibit superior durability, with a relatively low aging rate of solid electrolytes.

What is a solid state battery?

Solid-State Batteries: Solid-state batteries eliminate the risk of leakage due to the use of solid electrolytes, and the high thermal stability of solid electrolytes makes them safer in high-temperature environments. Additionally, the solid structure can help suppress lithium dendrite growth, fundamentally reducing the chance of short circuits.

How much energy does a solid state battery produce?

Solid-state batteries offer much higher energy density potential. Thin-film types can reach 300-800 Wh/kg, while bulk types are around 250-500 Wh/kg. Recent research by Mercedes and Factorial claims to have achieved 450 Wh/kg in a new solid-state battery type, which is 33% smaller and 40% lighter than comparable lithium-ion batteries.

Why are solid-state batteries more expensive than lithium-ion batteries?

The materials used in solid-state batteries, particularly the solid electrolyte, are currently more expensive than those in lithium-ion batteries. The manufacturing process itself is more complex and requires specialized equipment.

Are solid-state batteries safer than lithium-ion batteries?

Solid-state batteries are safer because they don’t use flammable liquids like lithium-ion batteries. This makes them less likely to catch fire and safer overall. Solid-state batteries can hold more energy in the same space or weight compared to lithium-ion batteries.
