(Nanowerk News) Battery operated Electronic devices are today a vast part of the overall electronic market place. Yet, there is one major bothering issue within almost every single device, instrument or gadget - "battery life time". Almost everyone is familiar with the annoying need to replace the battery or to charge it. It can be the laptop during a presentation, a wireless or cellular phone stopping during a very important conversation with a customer, or a camera in the middle of taking pictures. There are endless incidents of that kind that we face as consumers and users. In Industrial Electronics there are many, most harmful battery failures, causing disturbances and security threats.
From one side, batteries are not capable supplying high current pulses, from the other side most communication devices are power hungry, demanding high current pulses. Batteries are aimed to supply voltage continuously while delivering high current pulses is damaging their chemistry and shortening life time.
Many electronic devices are using communication protocols that are defined by various current pulses like GSM , Zigbi and WiFi. Other electronic devices such as digital camera or Smartphone need high current during a snapshot to operate the shutter, the flash led or data transmission. One of the best existing solutions today for extending battery life is Pulse Supercapacitors (SC).
A pulse supercapacitor is an "Energy storage" component with high capacitance and low internal resistance (ESR) that unlike a battery is built to deliver pulses of current almost endlessly (hundreds of thousands of charge/discharge cycles) and can be calmly recharged by a battery during the standby time between the pulses. Hybrids of Battery and SC are coming more and more popular and recognized by the engineers.
There are three limiting issues;
