Introduce the importance of lithium ion battery charger

Source: 2020 - 04 - 14 that hits: the importance of lithium ion battery charger current lithium ion battery application is very extensive, in addition to the industrial products or special equipment use, mass consumption field widely, such as electric bicycle batteries, strong light flashlight batteries, back-up power, form a complete set of equipment such as lithium ion battery, charger, also will inevitably produce a large number of market demand, the development of hot spots is to become a power supply manufacturers. Lithium battery charger need to point out is, lithium ion battery charging process and the nickel cadmium battery and nickel metal hydride batteries are completely different, is a complex electrochemical reaction process. Therefore, it is necessary to configure special charger to charge. Even the special lithium battery charger, due to the strict charging voltage tolerance requirements ( Average of 1%) , when a full charge, also need to distinguish between 4. 1 v and 4. 2v。 The quality of the charger for lithium battery life plays a vital role. When the charging voltage and charging current is too large, the lithium ion battery can damage even scrapped. So it is often said that sometimes is not the battery is broken, but the charge. At the same time, the continuous development of power electronics technology and switching power supply technology, changed the traditional linear power supply design train of thought. Therefore, completes the lithium ion battery chargers, to improve the reliability and working efficiency, ensure the safety of the battery, prolong the service life of the battery, have important engineering practical significance. Chemical reaction equations for lithium iron phosphate battery anode of lithium ion battery is a compound containing metal lithium, lithium iron phosphate (generally Such as lithium iron phosphate lithium iron phosphate, phosphoric acid lithium cobalt LiCoO2, etc. ) , graphite or carbon negative electrode ( Graphite is more commonly used) , the use of organic solvents as electrolyte between the positive and negative electrodes. When the battery, the anode is break down to form lithium ion, lithium ion through into the anode, electrolyte and embedded into the pores of the cathode carbon layer. The battery life ( The equivalent of discharge) During the embedded negative microporous lithium ions will move to the anode. Lithium ion is returned to the anode, the higher the discharge capacity, we usually say the battery capacity is the discharge capacity. So the battery charge and discharge process, the lithium ions between the positive and negative movement back and forth constantly, so the lithium ion battery, also known as the rocking chair batteries. The internal structure of the lithium iron phosphate lithium iron phosphate battery electrochemistry reaction equation is as follows: positive reaction: such as Li1 - xFePO4 + xLi + + xe - As shown in LiFePO4; The cathode reaction: xLi + 6 c + + xe As shown in LixC6; Total reactive: such as Li1 - , as shown in the xFePO4 + LixC6 LiFePO4 xc + 6.
