Why do smart phones use lithium batteries? What are its advantages?

At present, most smart phones use lithium batteries. So what are the specific advantages of lithium batteries that will make all mobile phone brands and even iPhones use lithium batteries as the first choice for mobile phone battery life? 01. What is a lithium battery? Lithium batteries are divided into lithium batteries and lithium batteries. Today's mobile phones and laptops use lithium batteries, which people usually call them lithium batteries, which are representative of modern high-performance batteries. The real lithium battery is extremely dangerous and is rarely used in daily digital electronic products. Lithium batteries are also known as secondary batteries (rechargeable batteries). Rechargeable lithium batteries are the most widely used in modern digital electronic products. The biggest difference between lithium batteries and lithium batteries is that the latter uses metal lithium as the negative electrode, while lithium batteries contain lithium. Elemental materials (graphite and petroleum coke) are used as electrodes, which restrain the high activity of lithium to a large extent and solve the safety problems of traditional lithium batteries. 02. Advantages of lithium batteries Since lithium batteries are now the first choice for smart phones, they will naturally have their advantages. Compared with traditional battery technology, lithium batteries can charge faster and last longer, and higher power density can achieve longer battery life, and at the same time, the body is lighter. As far as lithium batteries are concerned with mobile phones, the most important things are actually two: good safety performance and long cycle life. Tips1. Good safety performance and no pollution. Unlike traditional lithium batteries, lithium batteries are highly active and prone to short-circuit explosion accidents. Many new protection mechanisms have been added to the design of lithium batteries, which are also safer. No memory effect. The memory effect mentioned here means that some batteries will memorize the user's charge and discharge range and mode. After a long time, it will be difficult to change this mode, and can not do large-scale charge and discharge. Lithium batteries will not have a memory effect. . This is also the reason why lithium battery mobile phones can be charged as needed. Tips2. Long cycle life The service life of lithium batteries is generally 2-3 years. Generally, it can reach more than 500 times, or even more than 1000 times, and for lithium iron phosphate, it can reach more than 2000 times. For mobile phones, long cycle life means longer use time. For some high-quality batteries such as iPhone lithium batteries, after 500 charging cycles, the battery can still maintain 80% of its capacity.
