1. Cathode materials: Cathode materials should have high electrochemical stability, good electrical conductivity, low cost and stable price. Common positive electrode materials include ternary materials, lithium cobalt oxide, lithium manganese oxide, etc.
2. Anode material: The anode material should have excellent mechanical properties, high specific capacity, low open circuit voltage and good reverse reaction inhibition. Common anode materials include graphite, silicon, and graphene.
3. Thermal stability:During the operation of the battery, the electrode material and the electrolyte will have a chemical reaction, thereby releasing heat, causing safety problems such as overheating and burning of the battery. Therefore, it is very necessary to select electrode materials with better thermal stability.
4. Price and scalability: The price of an electrode material directly affects its application cost, so it is important to choose a moderately priced electrode material. At the same time, the development of scalable electrode materials can meet the needs of different application fields and battery structures.
In short, the correct selection of electrode materials for lithium-ion batteries plays a vital role in the performance and safety of the battery. To choose an electrode material suitable for one's own needs, factors such as the nature of the electrode material, thermal stability, price, and scalability should be fully considered.
