Electric vehicles are about to get a massive upgrade. Solid-state batteries, which use a solid electrolyte instead of a liquid one, offer double the energy density of traditional lithium-ion batteries. This means EVs can now travel over 800 miles on a single charge and recharge in under 10 minutes.

Beyond range and speed, solid-state batteries are also much safer. They are non-flammable and more resistant to extreme temperatures. The manufacturing process is also more sustainable, requiring fewer rare-earth minerals. Major automakers are racing to integrate these batteries into their upcoming models.

The impact on the global energy grid will be significant. EVs with these massive batteries can act as 'mobile storage units,' feeding power back into the grid during peak demand. This helps stabilize the grid and facilitates the integration of more renewable energy...
