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;

  • Size and shape; Most of Pulse SCs in the market are cylindrical and large in size to be integrated in the miniature trendy market.
  • Environment friendliness; some of the Pulse SCs contain organic electrolytes and solvents that are harmful, flammable and not accepted environmentally (i.e. Acetonitrile which is used in organic electrolyte based SCs).
  • Cost; Pulse SCs are known to be expensive and as so, are not able to join most of consumer electronics bills of materials.

All these three issues were challenged by Cellergy Ltd.

  • Cellergy manufactures its SCs by implementing Printing technology that enables to build flat, thin and in a wide range of sizes down to 12X12.5 mm, yet the smallest form factor of Pulse SCs in the market.
  • Cellergy’s SCs contain aqueous electrolyte and are green products.
  • Cellergy’s patented manufacturing process is based on Automation and Robotics, which helps to reduce costs to a level that enables them to be integrated not only in industrial products but also in consumer electronics.

Partial list of Cellergy’s SCs applications can show the large penetration into the electronic industry;

Industrial Electronics;

  • Automated metering (AMR)
  • GSM/GPRS Modules
  • M2M communication
  • Active RFID for animals tracking, vehicles tracking, prisoners tracking, medical equipment tracking, and container tracking, etc.
  • Medical drug delivery pumps
  • Fuel Automated payment solutions
  • Wireless computers mouse and keyboards
  • Home security
  • Home Automation
  • Electronic locks
  • Irrigation control
  • Energy harvesting for sensors
  • Energy harvesting for mechanical movement operations
  • Laser Range finders for civil and for military applications
  • Military  pulse applications
  • Cellular communication and led flash

Consumer Electronics;

  • Personal Pagers
  • Sound improvement of loudspeakers
  • Wireless audio devices
  • PDA’s

Supercapacitors contribute to a breakthrough in power management design. The combination of batteries and supercapacitors enables the transmission of pulses of the many electronic devices surrounding us, and results in extending the life of batteries of those devices, thus lowering end customer expenses and making it affordable for use.
