u003cpu003eNow, the reason why we can see lithium-ion batteries in many fields is mainly because they have the following advantages:u003c/pu003eu003cpu003e1. High voltage: the working voltage of single lithium-ion batteries can be as high as 3.7V or even higher, while the operating voltage of common nickel-cadmium and nickel-hydrogen batteries is only 1.2V. u003c/pu003eu003cpu003e2. High specific energy: Compared with other batteries, lithium-ion batteries of the same mass or volume can provide much higher energy. With the advancement of human technology, there are now some types of Li-ion batteries that can discharge more than 500Wh per kilogram, so their specific capacity will be much larger than traditional batteries. u003c/pu003eu003cpu003e4. There is no memory effect: other rechargeable batteries, if you want to recharge during use, you need to use up the remaining power, which is more troublesome and seriously affects the battery performance, while lithium-ion batteries It can be charged at any time, and the advantages are full. u003c/pu003eu003cpu003eu003cpu003eu003c/pu003eu003cpu003e5. Good cycle performance: For example, lithium iron phosphate can reach more than 2000 times, while other common rechargeable batteries generally have 300~600 times. Therefore, the use of lithium-ion batteries will greatly increase the battery life of electrical appliances with low current discharge and double the competitiveness of electrical appliances. u003c/pu003eu003cpu003e5. There is no memory effect: other rechargeable batteries, if you want to recharge during use, you need to use up the remaining power, which is more troublesome and seriously affects the battery performance, while lithium-ion batteries It can be charged at any time, and the advantages are full. u003c/pu003eu003cpu003e6. Small self-discharge: Under the same storage conditions and the same amount of electricity, the lithium ion battery retains more electricity. u003c/pu003eu003cpu003eu003cpu003e7. Wide operating temperature range: Generally, the operating temperature of lithium-ion batteries is −30~+60℃. It has good working performance at both high and low temperatures. The improvement of liquid and positive electrode is expected to be expanded to −40~+70℃. u003c/pu003eu003cpu003e8. It is more environmentally friendly, and the composition of lithium-ion batteries generally does not contain harmful substances. u003c/pu003eu003cpu003eu003cpu003eTable 1 Comparison of functional parameters between ordinary batteries and LI-ion batteriesu003c/pu003eTechnical parameters Ni-Cd batteries Ni-MH batteries Liquid lithium-ion batteries Polymer lithium-ion batteries Working voltage 1.21.23.63. 7 Weight specific energy (Wh/kg) 5065 100~160 120~170 Volume specific energy (Wh/L) 150 200 270~360 300~460 Cycles 300~600 300~700 500~1000﹥1000 Self-discharge rate (%/month) 25~3030~ 356~93u003cpu003eLithium-ion battery product page:/products/li-ion_battery.htmlu003c/pu003eu003cpu003eu003c/pu003eu003c/pu003eu003c/pu003eu003c/pu003eu003c/pu003e
