Solid-State Batteries : The Next Big Leap in Battery Technology
Introduction Batteries are everywhere in our phones, laptops, and electric vehicles. Most of these use lithium-ion technology, which relies on a liquid electrolyte to help lithium ions move inside the battery. While these batteries are good, they have some safety risks and limits to how much energy they can store. Solid-State Batteries are an exciting new type that promises to fix many of these problems. Let’s explore how they work, why they use solid electrolytes, and why they might be the future of energy storage. What Is a Solid-State Battery ? A battery has three main parts: -Anode (negative side) -Cathode (positive side) -Electrolyte (material that lets lithium ions move between anode and cathode. In traditional lithium-ion batteries, the electrolyte is liquid. In a solid-state battery, this liquid is replaced with a solid electrolyte—a solid material that lets lithium ions pass through but blocks electrons. How Do Solid-State Batteries Work? The basic working principle is si...
