LiFePO4
You must have heard this name many times but were unable to understand what it meant. Well, if this is the case then this blog is dedicated to you. Here, we will discuss history and early evaluation.
Basically, LiFePO4 (LFP) is a battery which helps your e-bike run smoothly. It stands for,” lithium-iron-phosphate battery”. It is the cheapest battery available in the market. It was discovered by John Goodenough at the University of Texas in the year 1996. It is a low cost, non-toxic, and full with iron kind of a battery. It has good thermal stability and gives excellent electrochemical performance. Also, it has high specific capacity of the order 170 mA·h/g. As it is packed with excellent characteristics, this battery has gained a name for itself!
Though it has gained a name for itself, it was not so in the beginning. First problem that the inventor had to face was of low electrical conductivity. It had a very simple but complicated solution. Reduce the particle size and coat those particles with conductive material such as carbon. Doping also helped. Electrical conductivity increased drastically. This was due to the presence of nanoscopic carbon which originated from organic precursors. All these additions to the battery made LFP what they are!
Later on when LFP were introduced, with all the additions, in the market, they were an instant hit. And, as usual, the rest is history!
