Lithium Metal & Lithium-Ion Battery Basics | POWERWIN

Introduction to Lithium Metal & Lithium-Ion Batteries

Lithium is a soft, silver-white metal and one of the lightest metals, making it ideal for use in modern batteries. In lithium-ion batteries, lithium typically exists as compounds in the battery’s positive electrode. These batteries power everything from smartphones to energy storage systems. At POWERWIN, we specialize in high-performance lithium batteries, including the popular POWERWIN BT100 LiFePO4 Battery.

What is a Lithium-Ion Battery?

A lithium-ion battery uses lithium compounds as the positive electrode (cathode). These rechargeable batteries convert electrical energy into chemical energy for storage and back into electrical energy when in use. They are found in countless applications, from electric vehicles to solar energy storage systems.

POWERWIN offers reliable, long-lasting lithium batteries that are designed to perform efficiently, even in challenging conditions. Visit our site to discover how our LiFePO4 batteries, like the POWERWIN BT100 12V 100Ah LiFePO4 Battery, can meet your energy needs.

Key Features of Lithium-Ion Batteries

1. Voltage (V)

Voltage refers to the potential difference between two points, allowing the flow of electrons. The working voltage of a battery is lower than its open circuit voltage due to internal resistance.

2. Battery Capacity (Ah)

Battery capacity measures how much charge a battery can store. A higher capacity means longer runtime. For example, the POWERWIN BT100 LiFePO4 Battery has a capacity of 100Ah, delivering consistent, reliable power for a variety of uses.

3. Internal Resistance (mΩ)

Internal resistance affects battery performance. Lower resistance means less energy is lost as heat, improving efficiency. POWERWIN batteries are engineered to minimize internal resistance, ensuring higher efficiency and better performance.

Additional Battery Concepts Explained

Discharge Cut-Off Voltage & Charge Limiting Voltage

Discharge cut-off voltage is the level at which a battery is fully discharged, while the charge limiting voltage is the point where charging switches from constant-current to constant-voltage.

Energy Density (Wh/Kg)

This measures the energy stored per unit of mass. Higher energy density means the battery can store more energy in less space. POWERWIN’s LiFePO4 batteries are optimized for high energy density and performance.

Self-Discharge Rate

This refers to the gradual loss of charge while the battery is not in use. The lower the self-discharge rate, the better the battery's storage performance. POWERWIN batteries are designed with advanced technology to minimize self-discharge, ensuring longer shelf life.

Cycle Life and Battery Durability

The cycle life of a battery is the number of times it can be charged and discharged before its capacity drops to 80%. Lithium-ion batteries generally offer longer cycle lives compared to other types. The POWERWIN BT100 LiFePO4 Battery is designed to offer thousands of charge cycles, making it an excellent long-term investment for energy storage.
