LiFePO4 is the Development Trend of Electric Vehic

Lithium iron phosphate is the Development Trend of Electric Vehicle Batteries

LiFePO4 battery is heart cells of electric vehicle.

Why electric car battery is the heart? It is beginning saying with the history of electric vehicles.Speaking of new energy electric vehicles, it is easy to be grouped into a new technology.In fact, the history of electric cars is much earlier than we imagined , even earlier than fuel vehicles. Thomas Davenport from America manufactured the first DC motor drive electric car in 1834 ; Scotsman Robert Davidson invented the electric drive train in 1834 ; Today we still use the tram patented in 1840 in UK; The world's first electric car was born in 1881 , the inventor is French engineer Gustave TeLufu, which is a lead-acid battery-powered tricycle.Gradually It comes out lead-acid batteries, nickel cadmium batteries, nickel metal hybrid batteries, lithium ion batteries, fuel cells as electricity.

You can see that although the electric car is earlier than fuel vehicle development, and achieved a certain scale in the early times,in modern times, to develop fuel vehicles, electric vehicle frustrated in the competition. But the real problem is that in the past lead-acid battery-based electric vehicle,subjected to the density of lead-acid battery life,power and many other restrictions, there has been no way to work out in the power source, which is a breakthrough on battery aspect that make electric vehicle development stalled.

Classification and the advantages and disadvantages of lithium battery
This issue gradually improve resolved until the lithium battery shows to us and was developed for 20 years.

Lithium is usually divided into two categories:


Lithium metal batteries: lithium metal batteries generally use manganese dioxide as a positive electrode material, lithium metal or its alloy as the negative electrode material, the use of non-aqueous electrolyte solution battery.


Lithium-ion batteries: lithium-ion battery is generally used lithium alloy metal oxide cathode material, graphite as the anode material, the use of non-aqueous electrolyte battery.


Although the energy density of lithium metal batteries is high, in theory, it can reach 3860 W / kg. However, due to their nature unstable and not be charged, it can not be used repeatedly as a power battery. While the lithium-ion batteries,because of the ability to be recharged, was regarded as the main driving force of development. But because of its different elements with the positive material in all aspects of performance vary widely,leading to a dispute on the route to increase cathode materials.

Usually we put up the main battery power: lithium iron phosphate batteries,lithium manganese batteries, lithium cobalt oxide as well as ternary lithium battery (three yuan nickel, cobalt and manganese).
Above all kinds of batteries have advantages and disadvantages, roughly summarized as follows:
Lithium iron phosphate:
Advantages: long life, large charge-discharge rate, safety, and high temperature resistance, harmless elements, and low cost.
Disadvantages: low energy density, low tap density (bulk density).
