The batteries of lithium-ion belong to the family of rechargeable batteries. The energy density of these batteries is very high. That is why the batteries are widely in use for manufacturing electronic products for consumers. There is a considerable difference between the LIBs and the disposable primary batteries of lithium. The LIB is a compound formed from intercalation of lithium instead of the regular metallic lithium to use as the electrode. The cells might have higher energy density, but they are very lightweight. The weight of the other types of rechargeable batteries that are of similar size is much higher than the LIB. You can find them inside the mobile phones, iPods, laptops, etc.
Technical explanation
When the LIBs discharge, the lithium ions start moving from the negative electrode which is the anode to the cathode or positive electrode. While charging the Lithium-ion batteries, the ions start moving in reverse direction. The negative electrode converts into the cathode, and the positively charged electrode takes the form of the anode. The lightweight lithium and the carbon makes up the electrodes of the battery. The lithium is an extremely reactive element. Its atomic bonds can store much energy. The translation generates high energy density.
Energy retention
The lithium batteries have the capacity to store 150-watt hours electricity if it’s a standard 1 kg battery. In contrast, the nickel-metal hydride batteries can only save 100-watt hours electricity in a standard 1 kg battery. Lead acid batteries store even lesser watt hours which is 25 in a 1kg battery. The energy retention ability of the lithium batteries is thus, way better than the other available form of batteries in the market. Moreover, the discharging rate is very low which implies that you won’t have to charge often. In a month, it will lose a maximum of 5% of the total charge if you do not use it.
