Recently, GAC Group‘s high-capacity all-solid-state battery production line, certified by CCTV, has generated significant excitement within the industry. What exactly constitutes the GAC solid-state battery architecture? The following content is compiled from publicly disclosed online information and is for reference only. Primary Sources of Information: 1. April 12, 2024: 2024 GAC TECH DAY (GAC TECH DAY 2024), themed “Science and Technology Horizon.” 2. November 21, 2025: The 23rd Guangzhou International Automobile Exhibition (2025 Auto Guangzhou). The GAC all-solid-state power battery leverages High Areal Capacity Solid-State Cathode Technology and the Third-Generation Sponge Silicon Anode Technology (a new nano-silicon composite anode). The all-solid-state electrode achieves an exceptional areal capacity of>5mAh/cm2, with a

New Idea for Battery Manufacturing: A Simple Press to Accelerate Electrolyte Wetting Press & Wet: A “Sponge-Inspired” New Strategy for Pouch Battery Electrolyte Wetting In the manufacturing process of lithium-ion batteries, electrolyte injection and wetting is an often-overlooked yet crucial step. The electrolyte must fully penetrate the separator and the interior of porous electrodes to form stable ion-conducting pathways, providing an efficient and safe operating environment for the battery. However, the electrolyte wetting process is typically extremely slow—even in automated production lines, it often takes 24 to 48 hours to complete. This not only severely slows down the production rhythm but also significantly increases manufacturing costs. A research team from

Here are 4 formulas for calculating the GITT diffusion coefficient in NEWARE‘s software. GITT is Galvanostatic Intermittent Titration Technique. Here is a brief explanation of the meaning and application scenarios of these four formulas, and the basic principles of GITT: GITT measures how the voltage (potential) of an electrode/cell changes with the amount of charge (lithium ions, for batteries) inserted/extracted—but with intermittent “rest periods” to minimize polarization (distortions from rapid charging/discharging). How It Works 1. Galvanostatic Step: Apply a constant current (galvanostatic) to the cell for a short time. This drives ions (e.g., Li⁺) into or out of the active material, changing its state of charge (SOC). 2. Rest Period:

Another “Nature” about battery: A ductile solid electrolyte interphase for solid-state batteries Solid-state lithium metal batteries are facing huge challenges under practical working conditions. Even when the ionic conductivity of composite solid-state electrolytes is increased to 1 mS cm−1, it is still difficult to realize long-life cycling of solid-state batteries above a current density of 1 mA cm−2 and an areal capacity of 1 mAh cm−2 (ref.). The fundamental cause is the brittle nature of the solid–electrolyte interphase (SEI) with sluggish lithium-ion transport and the resulting lithium dendrites and severe side reactions. Here we report a ductile inorganic-rich SEI that retains its structural integrity while allowing easy ion diffusion at high current densities and areal capacities.

Q1: About CAN and RS485, which are the basic improvements and functionalities that battery module or pack communication incorporates into NEWARE software? Can this data be saved in the database? Communication allows the device to communicate with the BMS (Battery Management System) in your battery. Once communication is established, the test page will display information such as the cell voltage. You can view the cell voltage information and then configure your software. For example, you can set the test to end when the cell voltage reaches 3.65V or trigger an alarm if the cell voltage is abnormal. The data obtained through communication from the BMS will be saved and will

7 most anticipated battery technologies in 2025, the first one is Sodium-ion batteries. Image source: CATLSodium-ion batteries hold great promise because they replace scarce lithium with abundant sodium, eliminating the need for cobalt and nickel. While the energy density of this chemistry still lags behind lithium-ion batteries, it offers a low-cost, non-flammable, and highly durable alternative.CATL’s recently launched sodium-ion battery (Naxtra) is a prime example of the industry’s high expectations. It retains 90% of its power at -40°C, boasts an impressive energy density of approximately 175 Wh/kg, and has a cycle life exceeding 10,000 charge-discharge cycles. Safety is a major selling point for CATL, as the battery demonstrated “no smoke,
