FAQs

Are 2025 batteries compatible with existing devices?

Most 2025 batteries retain standard 18/21mm cylindrical or pouch formats for backward compatibility. Voltage adjustments are managed via embedded BMS.

How much will 2025 EV batteries cost?

Projected at $75/kWh, down from $132/kWh in 2022. Sodium-ion variants may hit $50/kWh for grid use.

Do solid-state batteries require new charging infrastructure?

No—existing 800V DC fast chargers work. Solid-state’s lower internal resistance allows 350kW charging without thermal throttling.
