A new technology which develop the new kind of battery, many research occur to form different kind of battery which is made up of Abdument and inexpensive material. This new battery are low cost and use the renewable sources of energy.
In all over the world there large installation of wind and solar system. Requirements increased fast for economical , also for large backup storage of energy which provides power while sun set or according to the requirements. For most of the uses the lithium ion battery is still to expensive. Also to the other purpose of use like pumped hydro which required specific topography which is not easily available.
Now, many scientists from other countries and MIT develop a new kind of battery which is made abduntally and inexpensive which resolve these problems.
Structures of new kind of battery , which form by aluminum and sulfur as its two electrodes material and in between this there is molten salt from MIT professor donald Sadoway released notice and other countries like Canada, China, Kentucky, and Tennessee that ‘ I want something new to invent which is much better then lithium ion batteries which have small scale storage capacity and increased its uses’. Lithium ion battery not good for only expensive , it also have flammable electrolyte which is not good for transportation. So that the Sadoway started study on different elements which is cheap and earth element material used as the substitute of lithium. After the study they found aliuminium which is most earth abutment material. While doing experiment they find that the battery cell could cover hundred of cycles. As compare to lithium ion the cost of these cell have one sixth of the lithium ion cell. Totally the charging rate is depending on the working temperature which is 110 degrees celsius.
In new battery they used molten salt which have low melting points. Its have a biggest disadvantage , it make the dendrite which is narrow spikes of metal. It attached to the one end of electrolyte and when it grow contact to another end they cause short circuit. Third elements which is chloro – alluminiate salt . It run across the dendrite , According to the experiment these elements have high charging rate. All these experiment focus on to find the salt which have low melting point.
However, Sadoway says that the battery do not required any external heat source for maintaining the operating temperature . Heat naturally produce by electrochemical reaction while recharge and discharge the battery. Sadoway said when u charge the battery it produce heat and keep the salt from freezing and when it discharge it automatically produce heat. For example, In sun shine u store the energy and in sun set u used these stored energy in dark every day. Now focused on the size of installation according to there need. For small houses and small to medium business few tens of killowatts per hour of storage capacity. For larger insta utility scale of ten to hundred megawatts per hours. Smaller scale of battery can be used in practical life in such as electrical vehicle charging. Every one wants rapidly charging of battery because when the electric vehicles become common on road they need charge up once . According to the Sadoway the battery system having quick storage power and have quickly released according to the requirements. Many scientists take initiative to develop this quick fast charging and less expensive and large storage capacity of battery, these teams having members from China, MIT , Peking University , Yunnan University , The Wuhan University of technology , In Canada – Oak Ridge National laboratory. These company come to support the MIT energy.
