Guangzhou Automobile Group announced: Haopin will become the preferred model equipped with all-solid-state batteries in 2026

According to news on November 22, GAC Group reviewed this year’s NEXT plan to deepen the implementation of independent brands, energy ecology and internationalization at the 2023 Guangzhou International Auto Show on November 17, and announced plans to launch it in 2026 A major breakthrough was achieved in the installation of all-solid-state batteries into vehicles.

According to the latest disclosure from GAC Group, the GAC Aian brand will start mass production of all-solid-state batteries in 2026, and the first model to use this technology is Haopin.

GAC Aion Laboratory announced that it has successfully completed the experimental verification of the interface modification technology of solid-state batteries and announced relevant technological breakthroughs:

1. This technology will reduce the life decay of solid-state batteries by 50%;
2. After 150 weeks After cycling, the battery capacity will remain above 90%.

   

   Solid-state battery: the potential of the next generation of power batteries
3. Ultra-high energy density:over 400 Wh/Kg
4. Ultra-high safety:high temperature resistance, puncture resistance
5. wide temperature range operating window :Working at various temperatures

Challenges:

Since the solid-state battery interface is a solid-solid contact, resulting in:

• High contact resistance
• Poor stability

This causes the solid-state battery capacity to easily decay and the lifespan to decrease shortening, hindering its mass production application.

1. By specially designing the solid electrolyte composition, an interfacial buffer layer is induced on the surface of the negative electrode.
2. Reduce interface impedance and improve interface stability.
3. The cycle stability of solid-state batteries using interface modification technology is significantly improved. After 150 weeks, the capacity retention rate exceeds 90%, and the battery life decay rate is reduced by 50%.
4. We are accelerating the development of new solid-state electrolytes, solid-solid interface modification and other related technologies to optimize the comprehensive performance of solid-state batteries.
