EV Technology - Future Battery TechnologiesWhat is the main advantage of lithium-sulfur batteries compared to traditional lithium-ion batteries?AThey have a longer lifespan without degradationBThey are cheaper to produce but heavierCThey store more energy and are lighter in weightDThey use only sulfur as the active materialCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand energy storage materialsLithium-sulfur batteries use lithium and sulfur, which allow higher energy density than lithium-ion batteries.Step 2: Compare weight and energyBecause sulfur is lighter and stores more energy, these batteries are lighter and hold more charge.Final Answer:They store more energy and are lighter in weight -> Option CQuick Check:Higher energy + lighter weight = Advantage [OK]Quick Trick: Focus on energy density and weight difference [OK]Common Mistakes:Confusing lifespan with energy capacityThinking sulfur is the only material usedAssuming they are heavier than lithium-ion
