Prospects of Lithium Iron Phosphate Cells

Ⅰ. The prospect of lithium iron phosphate cells


High-performance cell is very important to the development of new energy industry. Compared with lead-acid and nickel metal hydride cells, lithium ion cells are of relatively high energy and relatively long cycle life.


According to the difference of the anode materials, the current lithium-ion batteries for sale can be divided into two categories. One is cobalt acid lithium, nickel cobalt manganese acid lithium and manganese acid lithium cell.


The voltage of this kind of battery is 4V or so, and its specific energy can reach 140-150 wh/Kg, but the safety of the battery is bad, which is determined by the chemical nature of the anode material. It is only suitable for use as a small-capacity battery.


The other is lithium iron phosphate cell, whose voltage platform is 3.2V. Its specific energy is slightly less than the former type of battery. But the advantage of the battery is good safety, long cycle life, low cost and good environmental compatibility, so it is very suitable for all kinds of new energy electric vehicles and new energy power supply.


Lithium iron phosphate cells can raise the storage efficiency of photovoltaic system to 95%, and currently most of the photovoltaic system also use lead-acid cells as energy storage devices.


However, in comparison, the lithium iron phosphate cell replacement can give full play to its advantages, including increasing battery energy storage efficiency, extending service life, reducing unit cost and so on.


The lithium iron phosphate cells for sale are normally used as energy storage devices that increase energy efficiency to 95%, far exceeding 70% to 80% of conventional lead-acid cells, and have 2000 charge and discharge life.


Although the cell needs further testing before investing in commercial photovoltaic power generation systems. However, research has shown that LiFePO4 batteries are expected to increase the efficiency of solar power systems, and lithium iron phosphate cells help reduce their installation and maintenance costs.


The production process of lead-acid cells and the acid solution and heavy metals such as lead and chromium in the old cells do long-term harm to the human and natural environment. At present, the old lead-acid battery is freely abandoned, and the recovery rate is low.


EU, Japan, and other countries have already implemented a strict battery production license system and manufacturer's recycling system, and China also launched the battery production license system.


Ⅱ. Superiority of lithium iron phosphate cells


1. Large specific energy (Up to 150WH per kilogram, 3 times the lead-acid battery, hydrogen-nickel battery).


2. Small size (30% less than hydrogen-nickel battery).


3. Light quality (70% lighter than traditional batteries).


4. Long cycling life (The number of cycles is more than 2,000 times).


5. Low self-discharge rate (3% per month).


6. No memory effect (Charge and discharge depth does not affect the capacity and life of lithium iron phosphate cells).


7. Non-toxic and no pollution (There is no toxic substance in the battery material).
