Sodium Ions

5 Minutes to Learn Sodium-ion Battery Testing: Electrical and Safety Performance

February 11, 2026

5 Minutes to Learn Sodium-ion Battery Testing: Electrical and Safety Performance I. Sodium Ions (Na+) A sodium ion is a sodium atom that carries a single positive charge due to the loss of one electron. Sodium ions play a vital role in both the natural world and biological life. For instance, they serve a critical function within cells, helping the human body maintain fluid-electrolyte balance and facilitate nerve impulse transmission and other physiological processes. Beyond biology, sodium ions are widely utilized in industrial applications, such as the development of sodium-ion batteries and as electrolytes in lithium-ion batteries, demonstrating their broad technological significance. II. Electrical Performance of Sodium-ion Batteries Compared to

Lithium Plating

Lithium Plating in Lithium-ion Batteries: Causes and Manifestations 2026

February 10, 2026

Lithium Plating in Lithium-ion Batteries: Causes and Manifestations I. Why Does Lithium Plating Occur? In simple terms, when the anode cannot promptly accommodate or intercalcate lithium ions migrating from the cathode, these ions “pile up” on the surface of the anode and are reduced into metallic lithium. As this deposited lithium continues to accumulate, it evolves into lithium dendrites. These dendrites typically manifest in four distinct morphologies: whisker-like, mossy, dendritic (tree-like), and spherical.   The main causes can be categorized into two major groups: operating conditions and battery states. 1. Operating Conditions (External Factors) Low-Temperature Charging: This is one of the most common causes. At low temperatures: The diffusion rate

Cathode Materials

Introduction to Cathode Materials for Lithium-ion Batteries 2026

February 9, 2026

Introduction to Cathode Materials for Lithium-ion Batteries I. Components of a Lithium-ion Battery A lithium-ion battery consists of four primary components: the cathode, the anode, the electrolyte, and the separator. The cathode material is the core component that determines key performance metrics, including energy density, capacity, stability, and safety of the battery. The performance of the cathode material directly impacts the battery’s cycle life, charge-discharge efficiency, and overall performance across various applications, such as electric vehicles (EVs) and consumer electronics.

Na battery working principle

Na batteries: Application and Testing Method Analysis 2026

February 8, 2026

Na batteries (SIBs) are considered a powerful complement to lithium-ion batteries due to their abundant sodium resources and lower production costs, showing immense potential especially in energy storage technology. As a type of secondary (rechargeable) battery, sodium-ion batteries function primarily through the movement of sodium ions between the positive and negative electrodes, operating on a principle similar to that of lithium-ion batteries. The electrode materials for sodium-ion batteries consist mainly of sodium salts, which are more abundant and cost-effective compared to lithium salts.   Working Principle of Na Batteries The working principle of sodium-ion batteries is similar to that of lithium-ion batteries, based on the insertion/extraction (intercalation/deintercalation) process of sodium
