The advantages and disadvantages of solid-state battery new energy vehicles are as follows:
advantage:
1. High energy density: Solid state batteries use solid electrolytes, which significantly improve energy density compared to current mainstream liquid batteries. This means that solid state batteries can provide longer range under the same volume and weight.
2. Long lifespan: Solid state batteries have better interface stability between electrolyte and electrode materials during cyclic charging and discharging, slower decay rate, and longer service life.
3. High safety: Solid state batteries have no liquid electrolyte, so there will be no safety hazards such as leakage or short circuit, greatly reducing the risk of battery accidents.
4. Fast charging speed: The electrolyte of solid-state batteries has high conductivity, making the charging process faster and more efficient.
5. Lightweight: The electrolyte of solid-state batteries is solid, which is lighter in weight compared to liquid electrolytes, helping to reduce the overall weight of the vehicle and improve its range.
Disadvantages:
1. High cost: The production process of solid-state batteries is relatively complex, resulting in high manufacturing costs, currently about tens of times that of ternary lithium batteries, making it difficult to apply on a large scale.
2. Relatively slow ion transport speed: The contact area between the solid electrolyte and the electrode material is small, which slows down the ion transport speed and may affect the charging and discharging performance of the battery.
3. Low technological maturity: Compared to liquid lithium batteries, the technological level of solid-state batteries is still in the development stage and has not yet been fully commercialized. Their performance and stability still need further verification.
