Performance of LiFePO4 Cell — Best Quality 3Voltage 35000mah Dd Li-Socl2 Battery

From:CTECHI GROUP Limited     Release time:2019-01-08

Overview:Lithium iron phosphate as cathode material of lithium battery is the safest cathode material for lithium ion battery at present. Although the compaction density is low and the voltage is low, it is still safe under the abuse conditions of extrusion, overcharge and short circuit due to the safety and stability of the cathode material. Because of its safety and stability, lithium iron phosphate battery has become an important development direction of lithium ion battery.

Lithium iron phosphate as cathode material of lithium battery is the safest cathode material for lithium ion battery at present. Although the compaction density is low and the voltage is low, it is still safe under the abuse conditions of extrusion, overcharge and short circuit due to the safety and stability of the cathode material. Because of its safety and stability, lithium iron phosphate battery has become an important development direction of lithium ion battery.


What makes lithium iron phosphate batteries so powerful?


A new study has answered why using lithium iron phosphate as a cathode often results in battery performance exceeding expectations: the secret lies in its internal flaws.


Material scientist Ming Tang said in a press release: "We all know that this material works very well, but scientists have been arguing about the real reason for it. This material is not so good in many respects, but sometimes it exceeds people's expectations.


Researchers found that in the process of making lithium iron phosphate, some atoms in its lattice appeared a dislocation phenomenon called antidislocation defect. Scientists have found that this inversion defect may explain the admirable performance of the material. This defect allows cathode materials to release and collect lithium ions from larger surface areas.


Previously, scientists assumed that lithium ions could only move in a single direction, limiting the surface size of materials that could release and absorb lithium ions. Microscopic imaging and computer models allow scientists to observe the movement of ions during battery charging. Scientists'analysis shows that the existence of inversion defects leads to a new direction of ion movement.

This defect effectively increases the surface active region of lithium iron phosphate nanorods and makes lithium ion transmission between the cathode and electrolyte more efficient. Tang claims: "Most battery cathodes are shaped into thin discs to increase the one-way movement of lithium ions. Our findings have changed our view on the optimal shape design of lithium iron phosphate. This defect allows lithium ions to move in many directions, which means that our design criteria for maximizing performance are completely inaccurate.


Even experts in battery research do not fully understand the electrochemical properties and processes of lithium-ion batteries and their components. But as more scientists design and analyze these electrochemical processes and properties, we will be able to improve them more and make the performance of lithium batteries as efficient as possible.
