What is the difference between a ternary lithium battery pack and a solid-state lithium battery?

Comparison of ternary lithium battery packs and solid-state lithium batteries1. Ternary lithium battery packs: mature technology and currently occupy the mainstream of the market. From the perspective of product maturity, Tesla Model series models in the United States have achieved breakthroughs, and Model 3 is about to scale sales , To further demonstrate the feasibility of ternary lithium power lithium-ion batteries. Model 3 uses a new 21700 battery, which is longer and thicker in appearance than the 18650 battery, and its energy density is also increased by 20%. The single battery capacity can reach 3~4.8Ah, which is a significant increase of 35%. There is no doubt that the current ternary lithium battery pack is already a mainstream product. 2.Solid-state lithium battery: has great technical potential and is expected to become a mainstream product in the future. From the perspective of technical potential, it is relatively difficult to increase the energy density of ternary lithium-powered lithium-ion batteries, and the energy density of all-solid-state lithium batteries is increased, which is theoretically more feasibility. First, the voltage platform of all solid-state lithium batteries has increased. Solid electrolytes generally have a wider electrochemical window than organic electrolytes, which is conducive to further improving the energy density of batteries; second, solid electrolytes can block the growth of lithium dendrites, and the range of material application systems is large. The improvement lays the foundation for a new type of lithium battery technology with a higher energy density space. Third, the current energy density of all-solid-state lithium batteries is about 400Wh/Kg, and the estimated maximum potential value is 900Wh/Kg, with more than 100% room for improvement. Solid-state lithium batteries are bound to be the mainstream products in the future. Which is better between ternary lithium battery pack and solid-state lithium battery? At present, the ternary lithium battery pack commonly used in mainstream electric vehicles has certain defects, because no matter from the chemical structure or the battery structure, the ternary lithium material is very easy to generate heat. If the pressure cannot be transmitted in time, the battery is at risk of explosion. This is also due to most of the spontaneous combustion incidents of electric vehicles that have occurred this year. Based on the comparison of the above-mentioned products, technology and safety, all solid-state lithium batteries have absolute advantages in terms of safety and technical potential, but ternary lithium batteries have considerable advantages in terms of product maturity and market penetration. On the whole, the current use of ternary lithium battery packs is the most wise choice for pure electric vehicles. However, once the all-solid-state lithium battery solves the problems of poor stability of metal lithium, it will explode with strong product substitution, or will subvert the power lithium-ion battery industry pattern.
