EVE Energy (70.370, 0.27, 0.39%) has rolled out its Longquan No.3 and Longquan No.4 all-solid-state batteries at its Chengdu.

According to EVE Energy (300014), the launch ceremony for Longquan No.3 and Longquan No.4 all-solid-state batteries, themed Core Breakthroughs for a Solid Future, was successfully held on March 17 at its Chengdu base in Sichuan Province.

The successful rollout of Longquan No.3 and Longquan No.4 marks a key technological milestone for EVE Energy. It will drive the industry toward higher safety standards and higher energy density, empower green and low-carbon development through technological innovation, and contribute to the global energy transition.

In a recent response to investor inquiries, EVE Energy stated that it has laid out technological and industrial plans in the solid-state battery sector. In September 2025, the company officially inaugurated its Chengdu mass production base for the Solid-State Battery Research Institute, where the Longquan No.2 all-solid-state battery was launched. The 10Ah Longquan No.2 cell boasts a high energy density of 300Wh/kg and a volumetric energy density of 700Wh/L, mainly targeting high-end equipment applications such as humanoid robots, low-altitude aircraft, and AI devices.

EVE Energy plans to achieve breakthroughs in all-solid-state battery manufacturing processes in 2026 and launch a high-power, highly environment-tolerant, and ultra-safe all-solid-state battery primarily for hybrid electric vehicles. In 2028, it intends to introduce a high-specific-energy all-solid-state battery with 400Wh/kg.

Separately, EVE Energy is proactively exploring sodium-ion battery applications in energy storage. In September 2025, its first large-capacity sodium-ion battery energy storage system was successfully connected to the grid and commissioned at its Jingmen base, officially entering commercial operation. This represents a key breakthrough in the company’s new energy storage technologies.

In December 2025, construction began on the headquarters project of EVE Sodium Energy. Upon completion, the park will become a leading industrial base for sodium-ion batteries in China. Its 2GWh production capacity will help fill market supply and demand gaps, promote large-scale applications in energy storage, AIDC, and other scenarios, and reduce the new energy industry’s reliance on lithium resources.
