Industry Insights

In-House Batteries Shift from “Option” to “Imperative” . Chery’s case demonstrates that when NEV gross margins significantly lag those of fuel vehicles, reliance on external battery suppliers creates a structural profit dilemma. Mastering next-generation battery technology is key to crossing this profit gap. Over the next 3-5 years, competition among leading automakers will expand to include “in-house battery ratio” and “next-gen battery production timelines.” For Investors: Prioritize “Engineering Capability” Over “Peak Specs” . In the solid-state battery space, engineering milestones such as 0.5 GWh pilot lines, 92% yield rates, and 217 process patents are more reliable indicators of actual production capability than laboratory specs like 600Wh/kg. The ability to “manufacture at scale” carries more investment value than the ability to “achieve impressive lab numbers.” For the Industry: 2027 as the Critical Validation Point . Multiple automakers, including Chery and Toyota, have set 2027-2028 as their target window for all-solid-state battery mass production. Whoever successfully navigates “production hell” first will gain both the technological definition power and market leadership in the next generation of traction batteries.
