For instance, lithium-ion batteries use lithium cobalt oxide in the cathode, which offers high energy density but may degrade over time. A study by Nagaura and Tozawa (1990) highlighted that the choice of electrode materials determines charge capacity and voltage levels.

2. Conductivity: Materials with higher electrical conductivity enhance efficiency. For example, graphite is typically used as an anode because it conducts electricity well while maintaining structural integrity. Research by Tarascon and Armand (2001) emphasizes that efficient electron and ion transport leads to improved charge-discharge rates.

3. Thermal Stability: The thermal properties of battery materials affect durability. Lithium iron phosphate (LiFePO4) has excellent thermal stability, reducing the risk of overheating or thermal runaway, which can lead to battery failure. A study by Goodenough et al. (2013) noted that stable materials contribute to longer cycle life.

4. Degradation Resistance: Certain materials resist degradation better than others. For example, silicon anodes can theoretically store more lithium but swell and fracture during usage, leading to performance loss. Research by Wu et al. (2012) indicates that materials with low expansion rates maintain structural integrity, enhancing longevity.

5. Environmental Impact: The choice of materials also affects environmental sustainability. Cobalt, used in many lithium-ion batteries, poses ethical and environmental challenges due to mining practices. A study by Elmquist et al. (2020) highlights that using more abundant materials, such as sodium, could lead to safer, more sustainable batteries.

6. Cost: Material selection greatly influences battery cost, which affects mass production and affordability. Cheaper materials like nickel and manganese can reduce overall production costs without significant loss in performance. Research by Niu et al. (2018) found that optimizing the material mix can balance cost and efficiency.

Each of these factors demonstrates the critical role battery materials play in determining overall performance, lifespan, and safety profiles.
