3 mins to learn Anode Materials of Lithium-Ion Batteries

December 18, 2024

Overview of anode materials of lithium-ion batteries In 1989, SONY company found that petroleum coke carbon materials could be used to replace metal lithium to make secondary batteries, which really opened the prelude to the large-scale application of lithium-ion batteries. In the next 30 years, three generations of products such as carbon, lithium titanate and silicon-based materials have been used as anode materials. This article will briefly introduce various lithium-ion battery anode materials according to the structural classification of anode materials. Characteristics of ideal anode materials The ideal anode material should have the following characteristics: 1.Low lithium insertion potential: To ensure a higher output voltage (the potential of the lithium

Three-Electrode System

10 mins Guide to the Application and Customization of Three-Electrode Systems In Battery Testing

December 13, 2024

In the development and production of batteries, the three-electrode test system is an important analytical tool for accurately measuring and analyzing the electrochemical properties of battery electrodes. Compared with the traditional two-electrode system, the three-electrode system can better dissect the electrode behavior and reaction kinetics in batteries, and is therefore widely used in material testing and pole-and-ear cell testing. In this paper, we will introduce in detail the principle, working mechanism, application scenarios, equipment and fixture selection of three-electrode testing, as well as the influence of pole-ear design in three-electrode testing, safety considerations, and the need for equipment features. 1. Three-electrode material testing 1.1 Principle of three-electrode testing A three-electrode

Discovering Atomic Force Microscope 2024

December 12, 2024

What is Atomic Force Microscope （AFM）? The Atomic Force Microscope (AFM) is a high-resolution scanning probe microscopy technique, jointly invented by Gerd Binnig, Heinrich Rohrer, and Calvin Quate in 1986. AFM operates by measuring the interaction forces between a sharp probe mounted on a microcantilever and the surface of a sample. This method allows for the detection of surface topography and physical properties of the sample at the atomic level. The working principle of Atomic Force Microscope Within an Atomic Force Microscope (AFM) setup, a highly responsive microcantilever is anchored at one extremity, while the opposing end carries a nanoscopic probe that interacts delicately with the specimen’s exterior. Due to

Cyclic Voltammetry

A Comprehensive Guide to Cyclic Voltammetry（CV）2024

December 10, 2024

Cyclic Voltammetry (CV) is a technical method for studying the behavior, kinetics, and rate-determining steps of electrochemical reactions at the electrode/electrolyte interface. This method is simple to test, rapid in response, and provides rich information from the cyclic voltammograms obtained. It has a wide range of applications in the fields of materials science, chemistry, environmental science, and biochemistry. Particularly, it is indispensable for advancing knowledge and technological progress in the field of electrochemistry. Through Cyclic Voltammetry, one can determine electrode reversibility, electrode reaction mechanisms, and perform quantitative analysis in electrochemical experiments.     1. The principle of cyclic voltammetry Cyclic Voltammetry (CV) is an electrochemical analysis technique that studies the

What Are Temperature Effects on Batteries? 2024

December 4, 2024

Temperature has a significant impact on battery performance, particularly in lithium-ion batteries, which are widely used in various applications due to their high energy density and stability. Here’s a detailed overview of the effects of temperature on batteries. Performance at High Temperatures High temperatures, especially above 35°C (95°F), can accelerate chemical reactions within the battery, leading to faster degradation and reduced lifespan .Overheating can cause thermal runaway, a dangerous condition where the battery can catch fire or explode . Prolonged exposure to high temperatures also increases safety risks and can lead to device failure . Performance at Low Temperatures Low temperatures, particularly below 0°C, impair charging efficiency as the internal

What Is HPPC Testing? 2024

November 21, 2024

1. What is High Power Pulse Characterization (HPPC)? The HPPC test (High Power Pulse Characterization) is a specialized diagnostic protocol used to quantify the dynamic power capabilities of a battery system. Unlike standard constant-current tests, the HPPC method subjects the battery to high-intensity current pulses to simulate aggressive real-world demands, such as rapid acceleration or regenerative braking in electric vehicles (EVs). Core Objectives of HPPC Testing: Dynamic Response Mapping: Understanding how voltage drops under sudden loads. Parameter Identification: Providing essential data for building equivalent circuit models (ECM). Efficiency Analysis: Identifying energy loss through internal resistance across various States of Charge (SOC). 2. Technical Principles: How the HPPC Test Works In
