1. Aircraft model lithium-ion batteries are urgently used in aircraft models. laypeople refer to them as drone lithium-ion batteries, while insiders refer to them as aircraft model lithium-ion batteries. One of the biggest characteristics of this type of battery is its light weight and its abi...

Use a heating pad to heat a single cell in a power lithium-ion battery for 1.7 hours. When heated for 1 hour, the temperature reaches 125 ℃, and the subsequent temperature remains unchanged. During this time, there is a cracking sound in the battery cell, but the sound is not clear. After the...

When the heat released by SEI film analysis causes the cell temperature to reach 180-200 ℃, the positive electrode begins to undergo analysis. During the positive electrode analysis process, atomic oxygen is released, which has a high activity and can cause severe oxidation analysis of the el...

Breakdown of Electric Vehicle Fire Cases The breakdown statement of electric vehicle fire cases states that most of the causes of the fire are due to thermal runaway of power lithium-ion batteries. By decomposing the ignition time of a certain type of electric vehicle within...

3、 Air coupled ultrasonic testing equipment A crucial function of this device is for battery edge testing, such as testing the effectiveness of aluminum plastic film sealing. The sealing has defects and wrinkles, which can easily cause leakage. The traditional testing metho...

1、 X-ray lithium-ion battery testing equipment The X-ray lithium-ion battery testing equipment can automatically determine, store data, identify and isolate defective products, achieve automatic control of the entire detection process, effectively identify defective product...

Although lead-acid batteries have a low energy density, their chemical composition is not as active as lithium-ion batteries, and their technology is already quite mature, with a low probability of short circuits. Additionally, they are made of metal grid materials made of lead material, which have...

Lithium ion batteries, as a crucial source of power for electric vehicles, have the characteristics of high energy density, light weight, and excellent attenuation resistance. However, as a crucial chemical component of batteries, lithium ions have strong activity. Once a short circuit occurs,...

In terms of its safety performance, honeycomb batteries adopt a design of multiple independent cells and are combined through a honeycomb structure. Even if a certain cell experiences thermal runaway, this structure will prevent the entire battery pack from catching fire. The honeycomb battery...

The earliest use of mobile phone batteries was nickel cadmium batteries, also known as the first generation mobile phone batteries. This type of battery has a low capacity and a memory effect. The crucial materials used for production are nickel and cadmium. Due to environmental pollution and...
