How to determine the charge/discharge cut off voltage of a lithium-ion battery? And what is charge/discharge cut off voltage? What is charge/discharge cut off voltage? The charge/discharge cutoff voltage refers to the upper and lower limits of the voltage set during the charging and discharging process of a lithium-ion battery to avoid battery damage, ensure safety, and extend its service life. Charging Cut-off Voltage: Definition: The highest voltage a battery is allowed to reach during charging. When the battery voltage reaches this value, the charging process must be stopped or switched to trickle charging/stop charging. Purpose: (1) Prevent overcharging: Continuing to charge beyond the cut-off voltage is called overcharging. (2)

The ever-increasing demand for large-size lithium-ion batteries from electric vehicles has driven the accelerated development of cell specifications with higher energy density and better pack efficiency. By the end of 2024, electric vehicles accounted for approximately 4% of the global passenger vehicle fleet, and this is projected to quadruple by 2030. For automotive applications, LIB (Lithium-ion Battery) R&D revolves around cost, energy density, and power capability, while also considering safety and lifespan, resulting in various chemical systems, cell specifications, and integration solutions. EV batteries range from 18650 cylindrical cells (≈3 Ah) to large-size pouch and prismatic cells exceeding 100 Ah, each with trade-offs in cycle life, thermal performance, energy density,

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:
