Day by Day,Smart phones are getting even more smarter with their extra-ordinary features and stunning looks. Yet the batteries that power them have remained the same since years and lagged behind electronics in terms of innovation.
Usually,Lithium-ion batteries are used in mobiles and they are the most common type of batteries used in consumer electronics.
With the emerging mobile phones and devices that require much power and fast charging,the demand for batteries which are more powerful than the existing ones have increased.Nothing can be more frustrating than a dead battery at the time of emergency or at times when we are discussing some important issues on calls.
To create the batteries that are compatable with the present day needs and that can slow down the loss of charge effectively than the existing ones,Researchers at the University of Illinois at Urbana-Champaign have developed tiny but high-powered, rapid-charging batteries that fit the description “small but terrible.”
These microscopic batteries could enable sensors or radio signals that broadcast 30 times farther, or devices 30 times smaller.They are considered to be the most powerful micro-batteries that are almost 1000 times stronger than existing lithium batteries and pave the way for smart-phones that could be charged in just one second.
Present power sources force users to choose between power and energy i.e.,if u want high energy you can’t get high power and vice-versa.But for most of the modern applications,you really need both.
“That’s what our batteries are starting to do. We’re really pushing into an area in the energy storage design space that is not currently available with technologies today,” said graduate student James Pikul, first author of the paper.
The new micro-batteries offer both power and energy.Like all batteries, they have two components, the anode (minus side) and cathode (plus side). The key to these batteries is an internal three-dimensional micro-structure that combines the battery’s anode and cathode “at the microscale”.
The scientists developed an anode that matches with a recent fast-charging cathode design and created a new way to integrate the two components at the microscale that enabled the battery to work with high efficiency.They are also planning to integrate their batteries with other electronic components at low cost.
This new technology could find its way to consumers in about 1-2 years.It will replace super capacitors in radios and personal electronics in near future.
Thus,besides consumer electronics,these new micro-batteries could not only power future mobiles but also can be used for medical devices, lasers, sensors and other high-powered applications.They can even be used to jump-start a dead car battery.
