The electrification of the energy sector is crucial for reducing pollution from fossil fuel power plants, but current lithium-ion battery technology has limitations. Solid-state batteries are emerging as the future of energy storage, offering significantly higher energy density, faster charging times, longer life cycles, and reduced fire risk compared to lithium-ion.

Why it matters

Solid-state batteries have the potential to accelerate the transition to renewable energy sources like solar and wind by improving energy storage capabilities. Their improved safety and performance characteristics could also enable wider adoption of electric vehicles.

The details

Solid-state batteries use solid electrolytes instead of the liquid electrolytes found in lithium-ion batteries. This allows for higher energy density, faster charging, and reduced fire risk. The first electric vehicle with a solid-state battery will debut in China this year, and major automakers like Toyota and Mercedes plan to incorporate the technology into their higher-end models by 2027 and 2028.

• The first EV with a solid-state battery will debut in China in July 2026.
• Toyota and Mercedes plan to use solid-state batteries in their higher-end car models in 2027 and 2028.

What’s next

As solid-state battery technology continues to mature, it is expected to play a key role in enabling wider adoption of electric vehicles and renewable energy sources.
