NASICON Solid Electrolytes: LATP/LAGP R&D, Synthesis & Modification
In the wave of solid-state battery technology, NASICON-type solid electrolytes have become core competitors for commercialization due to their excellent air stability, high ionic conductivity and low cost. Among them, LATP (Li₁₊ₓAlₓTi₂₋ₓ(PO₄)₃) and LAGP (Li₁₊ₓAlₓGe₂₋ₓ(PO₄)₃) have attracted much attention from the scientific and industrial communities with their excellent comprehensive performance. However, the traditional R&D model…
Aramid Lithium Battery Separator: Dual Safety Design for Thermal Runaway Prevention
The core risk of lithium battery thermal runaway often stems from the “dereliction of duty” of the separator — traditional polyolefin separators have limited heat resistance, and it is difficult to balance the shutdown temperature and rupture temperature. They either fail to timely block ion transport in the early stage of thermal runaway, or break…
Lithium Battery Separator Selection: Core Logic for Safety & Performance Balance
Among the core components of lithium batteries, although the separator does not participate in electrochemical reactions, it is known as the “third electrode” — this thin film with a thickness of only 4-25μm not only controls the safety bottom line of the battery, but also determines the upper limit of energy density and cycle life….
Separator Parameters & Processes: Impact on Lithium Battery Performance
As the “ion channel” and “safety barrier” of lithium batteries, the parameter design and process selection of separators directly affect core indicators such as battery internal resistance, self-discharge rate, and low-temperature performance. For separators of the same material, even small differences in thickness or porosity may lead to vastly different battery performance; the two processes…
Ceramic Coated Separator: Safety Upgrade for High-Performance Lithium Batteries
Among the core components of lithium batteries, the separator is as critical as a “heart valve” — it must isolate the positive and negative electrodes to prevent short circuits, while opening up channels for lithium ion transport. Although traditional polyolefin separators (PE, PP) are widely used, they have fatal shortcomings: the rupture temperature of PE…
Lithium Battery Separator Performance Testing: Key Quality Indicators
Lithium battery separator performance directly determines battery safety, cycle life and charge-discharge efficiency — a qualified separator must not only allow lithium ions to pass smoothly like a “precision sieve”, but also resist puncture and high temperatures like a “solid barrier”. Performance testing is the core link to verify separator quality, among which air permeability,…
Lithium Battery Slurry Stirring: From Dispersion Mechanism to Lab Scientific Control
Lithium battery slurry stirring is the cornerstone of high-quality electrode preparation and reliable battery performance in laboratory research. As a typical complex multiphase suspension system, lithium battery slurry consists of active particles, conductive agents, binders, and solvents. The significance of stirring goes far beyond “uniform mixing”; it is essentially a comprehensive physical and chemical process…
Lithium Battery Slurry Abnormalities: Causes, Mechanisms & Control Strategies
lithium battery slurry abnormalities are common challenges in the electrode manufacturing process of lithium-ion batteries, directly affecting the quality of electrode sheets and the overall performance of batteries. As the core link in electrode preparation, slurry mixing involves the uniform compounding of active materials, conductive agents, binders, and solvents. Any imbalance in the multiphase interface,…
Essential Guide to Vacuum Mixer for Lithium Battery Slurry: Fix 15 Common Mixing Issues
Before addressing common issues, it’s crucial to understand the role of a vacuum mixer in lithium battery slurry preparation. A vacuum mixer combines high-speed stirring with vacuum degassing to ensure uniform dispersion of active materials, binders, and solvents, while eliminating air bubbles that can cause coating defects, reduced battery capacity, and safety hazards. Unlike traditional…
