Principles of lithium titanate battery work response.lithium batteries for boats Processor

　　Lithium titanate batteries are composed of positive and negative electrode plates (positive active substances are ternary lithium, and negative electrodes are lithium titanate), diaphragm, electrolyte, pole ear, stainless steel (aluminum alloy) shell, etc. Positive and negative pole plates are the areas of electrochemical reactions. The diaphragm and electrolyte provide a transmission channel of Li, and the pole ears play a role in guiding the current.

　　When the battery is charged, Mi+migrate from the three yuan lithium material to the surface of the crystal, remove it from the positive plate material, enter the electrolyte, through the electrolyte, pass through the diaphragm, and then migrate to the negative electrode lithium titanic acid crystal. The surface, then embedded in the structure material of the lithium titanate spinel. At the same time, the electron flowing through the positive aluminum box, through the electrode ear, battery pole column, load, negative electrode column, and negative ears to the negative aluminum foil electrodes, and then flow to the lithium titanate negative electrode, so that the charge is up to balance Essence

　　When the battery is discharged, Li is removed from the structural material of lithium titanium spinel, enter the electrolyte, passes through the diaphragm, and then migrates to the surface of the ternary lithium crystal through electrolytes, and then re -embedded into the ternary lithium material. At the same time, the electronic meridian -flowing aluminum foil electrode flows to the negative electrode, and the aluminum foil electrodes of the anlarm, the battery negative column, the load, the positive pole column, and the positive polar ear flow towards the battery are up to the battery. Make the charge up to balance.

　　When the battery is charged, the electrons are lost, the lithium ion is removed, and it is embedded in the negative electrode; the negative electrode is embedded in the lithium ion while the electrons are obtained into the lithium -rich state. The process during discharge is exactly the opposite. During the reaction of li+embedded or dehydration, lithium titanate (li4Ti5012) is an ideal embedded electrode material. LI+insertion and dehydration have little effect, so it is called "zero -changing" material, so It guarantees its good circulation performance.

　　Lithium titanate has two different phases of molecular structure one -LI7TI5012 and LI4TI3012. The crystal structure of the LI7TI5012 and the crystal structure of the LI4TI5012 are all spylite structures, and the lattice constant changes very small, and the volume changes are also small. It can avoid the back and forth of the electrode material in the recycling cycle and cause the structure to destroy the structure, thereby improving the circulation performance and service life of the electrode, reducing the increase in capacity with the increase of the number of cycles, making lithium titanate have excellent circulatory performance Essence
