Battery Life Increased Drastically, Charging Time Reduced To Minimum
Having a cellphone with 'exceedingly' longer battery life is not a distant dream now. Engineering team led by Harold H. Kung, Professor of Biological and Chemical Engineering at McCormick school of Engineering and Applied Sciences have developed a Lithium ion electrode which drastically increases the performance of conventional cell phone battery in both life as well as in terms of energy capacity. The electrode is perhaps another advancement in #-Link-Snipped-# that we have recently seeing.
#-Link-Snipped-#Kung led team claims that the electrode by them can increase the battery life more than 10 times the present and can be charged within 15 minutes. The battery is 5 times more effective than the Lithium ion battery currently in use. The study has been published in this week's edition of journal #-Link-Snipped-#. The paper titled #-Link-Snipped-# explains the processes involved in making the electrode.
There are possibly two major limitations which the battery industry is facing. The first one is the energy capacity of the capacity of the battery as to how much charge it can store. As the energy stored in the battery is less in quantity, naturally much lesser applications can be accessed on your device. You are limited to the programs which require less amount of energy and can enjoy the power consuming applications for much smaller duration of time, if you wish to conserve the battery.
The second is of course the time required to charge. Even the most professional batteries require a couple of hours to charge fully. Attempts have been made to reduce this idle period of charging to about 15 minutes much after seeing the rising trend among rural and urban population to use iPods and Cellphones.
Both these drawbacks are tackled in this research using a unique approach by increasing the number of Lithium atoms in the electrode involving the stabilization of silicon. This is done by sandwiching it in between two Graphene sheets. In other words, we are having an increased energy density coupled with prevention of the losses caused by expansion and contraction of Silicon. Kung's team also created minute holes in the Graphene sheets which would boost the reaction between Lithium and Silicon thus providing a 'Short Cut' and reducing the battery charging time.
The commercial success of this battery will depend on how far it can be accommodated in the proposed devices as there are even other innovations in this field and currently under a deep thought by the industry experts. If the resulting battery is cheap and up to the mark on quality, it will be absorbed in the industry easily.
