Solid-State Batteries

●Concept

-Use solid electrodes and solid electrolytes (ceramics, polymers, or glass) instead of liquid ones—eliminating separators and improving safety, energy density, and durability.

●Working

Operate like Li-ion batteries —lithium ions move between cathode and anode through a solid electrolyte, ensuring stable performance and preventing leakage or fire.

●Advantages

-Higher Energy Density - Compact, long-range EV batteries

-Safer - No risk of explosion or leakage

-Longer Lifespan

-Space Efficient - No safety hardware needed

●Challenges

-High Cost & complex manufacturing

-High internal resistance, poor cold-weather output

-Unproven scalability at commercial EV levels

●Applications

-Ideal for EVs, pacemakers, wearables, RFIDs— where high capacity and compactness matter.

●India - next-gen battery revolution, powering India’s EV future under PM E-Drive and FAME-II with safer, faster-charging, high-capacity solutions.
