Technical FAQs 4

Can a soldering iron contact a battery?

Do not allow the soldering iron to make direct contact with the bodies of the batteries. Proceed with the sol-dering quickly within 5 seconds while maintaining the iron tip temperature at about 350°C, and do not allow the temperature of the battery bodies to exceed 85°C. (Heat resistance BR type is 125°C)

How do you solder a battery?

Proceed with the sol-dering quickly within 5 seconds while maintaining the iron tip temperature at about 350°C, and do not allow the temperature of the battery bodies to exceed 85°C. (Heat resistance BR type is 125°C) Soldering with a dip-soldering bath can be used by con-dition but do not allow the temperature of the battery bo-dies exceed 85 C.

What is a thermal management system in a lithium battery?

Thermal management systems help regulate the temperature of lithium batteries during operation. Typical systems include heat sinks, cooling fans, thermal pads, and temperature sensors. Heat sinks dissipate excess heat from the battery to prevent overheating. Cooling fans improve airflow around the battery, aiding in heat dissipation.

How to solder battery terminal to printed circuit board?

Panasonic adopted the laser welding method to solder battery terminal onto the printed circuit board. In the comparison of 20φ series battery, while the ten-sile strength of conventional resistance welding method was 20-50N (about 2 to 5 kgf), laser welding method was 100N (about 10kgf) and the variations was comp-ressed to 1/2.
