IC Batteries
1. What are IC Batteries?
IC batteries, also known as integrated circuit batteries or micro batteries, are small batteries integrated into microchips or integrated circuits to provide a stable power supply to ICs in the absence of an external power source to maintain their functions.
2. What are the Types of IC Batteries?
IC batteries are divided into rechargeable batteries and non-rechargeable batteries. Rechargeable IC batteries can be charged using an external power source, while non-rechargeable IC batteries are designed to have a fixed service life and need to be replaced afterwards.
3. What are the Materials of IC Batteries?
IC batteries can be made of a variety of materials, including lithium, silver oxide, and zinc-air batteries. They are usually less than 1 mm in size and have a lower capacity compared to standard batteries. However, they are designed to operate for a long time with extremely low power consumption, which is very suitable for applications that require low power consumption and long-term autonomous operation, such as medical implants, RFID tags, and sensors.
4. Collaborative Application of Batteries and ICs
1) Battery Basic Structure
It is composed of a cathode (reduction reaction), an anode (oxidation reaction), an electrolyte (ion transport medium), a separator (preventing short circuits), and a collector (current collection). Types include lithium-ion, nickel-hydrogen batteries, etc.
Cells are connected in series or in parallel to form battery packs and finally integrated with BMS and other modules to form a complete battery pack.
2) Role of IC in Battery System
Energy Management: Charging and discharging control, temperature monitoring, and overvoltage protection are achieved through dedicated ICs, such as power management chips (PMIC) to optimize energy efficiency.
Communication and Control: Microcontrollers (MCU) or sensor interface ICs are used to ensure data transmission and balanced control between battery packs.
3) Typical Cases
Mobile Devices: High-density BGA packaged ICs are used in combination with lithium polymer batteries to achieve a lightweight design.
Energy Storage System: Multi-cell battery packs achieve remote monitoring and fault diagnosis through CAN bus communication ICs.
