On April 7, Liu Tao, CEO of SAIC Zhiji, said on Weibo that the first generation of Zhiji L6 solid-state battery was officially named “light-year solid-state battery”.
Liu Tao said that although it is the first generation of solid-state batteries, it has achieved an easy range of 1000 kilometers with almost the same weight and more than 30% of electricity, which is the value of solid-state batteries instead of liquid batteries.

According to official data, the solid-state battery is based on the quasi-900V super performance platform, the positive electrode is coated with ultra-high nickel material with nano-scale solid electrolyte developed by ourselves, and the negative electrode is a new generation of high specific energy composite silicon-carbon material.
Through high-tech materials and processes, the energy density of the battery is greatly increased and the vehicle is endowed with ultra-long range performance.
It is reported that the Zhiji L6, which is equipped with the solid-state battery, can exceed 1000 km CLTC mileage and can travel from Beijing to Dalian on a single charge, and it is easy to commute from Shanghai to Hefei.

By using the self-developed “high ionic conductivity, high temperature resistant solid electrolyte” and “dry solid electrolyte layer integrated molding” technology, the overall internal resistance of the cell is greatly reduced and the ultra-fast charging performance is obtained.
High and new technology also solves the problem of high expansion of silicon-based materials and ensures the stability, cycle performance and safety performance of solid-state batteries.
In addition, officials also said that the solid-state battery reached the battery safety standard far exceeding the national standard, achieving “no heat spread and no fire in the whole package”.
Dry integrated forming of high temperature resistant solid electrolyte greatly improves the safety of the cell, so that it will not have the phenomenon of electrolyte leakage of traditional batteries, it is more difficult to burn and explode, and has ultra-high level of safety.
It has been revealed that Zhiji Automobile has a long-term solid-state battery development plan and has clearly planned at least three generations of solid-state battery products.
