Stability of battery performance under extreme temperatures.
Stability of battery performance under extreme temperatures.
The pace of life is accelerating and the application fields of the world, such as consumer applications, smart cities, smart living, smart healthcare and smart industry, are changing rapidly. This also poses a challenge for power supplies.
Batteries are being used in increasingly extreme environments! How will the electrical performance and stability of batteries be affected by extreme temperatures?
The battery is in a low temperature environment:
A sharp increase in internal resistance: At low temperatures, the diffusion of electrolyte ions slows down. This significantly increases the internal resistance, causing a sudden drop in output voltage and potentially resulting in the device shutting down prematurely.
Capacity attenuation: Experiments have shown that the discharge capacity of button batteries is lower at -15°C than at 17°C.
Voltage reduction: It is easy to trigger the low voltage protection of the equipment when the discharge voltage drops from room temperature to sub-zero temperature.
The battery is in a high temperature environment:
Electrolyte decomposition: The electrolyte in standard lithium batteries can easily volatilise or decompose at temperatures above 60°C, which can cause leakage, bulging or even explosions.
Accelerated self-discharge: Chemical side reactions increase at high temperatures, reducing battery capacity and shortening the storage life.
How can battery performance be stabilised under extreme temperatures?
Power Glory products boast technical advantages such as an ultra-wide temperature range, high safety standards, a long lifespan and a high energy density. The company's wide temperature series of button batteries (CR-HT, CR-D and CR-T series) use new lithium battery technology and can perform well in harsh temperature environments. These batteries are ideal for various extreme environmental applications, including cold chain transportation, outdoor monitoring, automotive TPMS, industrial sensors and medical equipment, breaking industry barriers.
