High rate discharge battery

What is a High rate Discharge Battery?

A lithium-ion battery is a type of rechargeable high-discharge battery. Its operation primarily relies on the movement of lithium ions between the positive and negative electrodes. During charging, lithium ions (Li+) move from the positive electrode to the negative electrode via the electrolyte, and the negative electrode becomes lithium-rich. During discharge, the process reverses, with lithium ions returning to the positive electrode. These batteries, often made with lithium-containing materials as electrodes, represent a high-performance modern energy storage solution.

The high discharge rate of a battery refers to its ability to charge and discharge at a faster rate compared to average batteries. A high-discharge battery can handle a high current output, which depends on the movement of lithium ions across the electrodes, electrolyte, and their interfaces. The discharge rate is measured in "C," representing the ratio of the charge/discharge current to the battery's capacity. For example, a 2000mAh battery discharged at 2C would deliver a 4000mA current, while 1C would deliver 2000mA.

At Ampxell, a high rate discharge battery is defined as one capable of handling a pulse discharge of over 40C and a continuous discharge of 10C, making it suitable for high-current applications such as drones, RC models, and power tools.

Normal Battery VS High rate Battery

The internal resistance of high rate battery is smaller than that of normal battery, so it has higher discharge platform, excellent output power.

Why Choose High rate Discharge Batteries?

Standard batteries are unsuitable for rapid charging as they risk lithium plating on the negative electrode, causing degradation or, in extreme cases, internal short circuits leading to fires. High-discharge batteries are critical for applications requiring faster charging and higher output. With growing demands across industries, these batteries are widely used in drones, emergency power supplies, RC vehicles, power tools, and more.

High rate discharge Cell Applications

Ampxell’s high-discharge cells cater to various industries, including RC hobbies, power tools, electric racing motorcycles, drones, and portable power stations. For example, Ampxell's high-discharge pouch cells are ideal for vehicle jump starters due to their compact size and powerful output.

How to Charge High rate Discharge Lithium Batteries

1. Activating New Batteries: A new battery may enter a dormant state after storage. Perform 3-5 regular charge-discharge cycles to activate it.
2. Charging Methods for Used Batteries: Charge frequently, avoiding deep discharge, and use appropriate chargers to ensure safety and longevity.
3. Safe Voltage Range: Keep the voltage between 2.8V and 4.2V to maintain battery stability.
4. Storage: Store batteries half-charged in a cool, dry place and recalibrate every 3-6 months.
