ITX121025A is a very compact 2,5V solid-state micro-battery featuring a capacity of 250 µA.h. Battery dimensions are less than 3,2 x 2,5 x 2 mm.
ITX121025A is ia fast-rechargeable solid-state micro-battery delivered in the form of Surface Mounted Devices (SMD).
These micro-batteries are really compact and fit within a volume of # 10-15 mm3; we can easily customize their form factors by changing the area and the thickness of the battery which can be less than 330 µm if necessary.
What is probably unique in these micro-batteries is that they obviously behave like a battery at 2,5V but they are also able to deliver power and high peak currents, the same way as supercapacitors. ITX121025A is able to deliver peak currents of around 175 mA. This is more than enough to power a RF transmission under various protocols (Bluetooth, Zigbee, etc…) or an ePaper display.
This is due to the fact that all our micro-batteries have very low internal resistance; this also explains why these micro-batteries do recharge very quickly: 50% of the charge is reached after 40 to 60 second charging times and more than 75% in less than 5 minutes; they withstand more than 2000 cycles at 75% Depth of Discharge..
Their typical lifespan is more than 10 years with an operating temperature range up to -40°C +85°C
Because they are fully solid and do contain neither Lithium metal nor organic solvents , they are totally safe (no risk of explosion) and easy to recycle like any other SMD components.
Because they are SMD, they can be assembled in standard automated assembly lines (pick and place, reflow soldering).
These micro-batteries are typically used to back-up RTC, PLCs, microcontrollers and memories (DRAM/SRAM and SSDs) in case of failure or shutdown of the main power supply, to power autonomous and wireless sensor networks or mobile phone peripherals.
They can be used in a lot of other applications:
- To store energy collected from energy harvesters and deliver the required power to RF transmitters;
- To power-assist primary batteries and deliver the power to boost any RF communication (Bluetooth, ISM, Zigbee and even LoRa and Sigfox)
