Nowadays, lithium batteries have become an indispensable part of people’s daily life. From smartphones to laptops, and even electric vehicles, lithium batteries are widely used. In the field of batteries, lithium batteries have developed rapidly and can be divided into different categories according to their properties and uses. This article will introduce the types, characteristics, advantages and disadvantages of lithium batteries.
1. Lithium cobalt oxide battery
Lithium cobalt oxide battery, also known as “LiCoO2 battery”, is one of the first lithium batteries to be commercialized. This kind of battery has the advantages of high energy density, large capacity, light weight, etc., and is widely used in electronic devices such as laptops, mobile power supplies, etc. However, lithium cobalt oxide battery also has some obvious disadvantages, such as fast voltage drop during discharge, low charging rate, large damage from over-discharge, etc.
At present, with the progress of science and technology, new types of lithium cobalt oxide batteries have also appeared, such as “ternary batteries”, which mix nickel, cobalt, and manganese together, and the battery capacity has been further improved, so they are widely used in mobile phones, laptops and other devices.
2. Lithium iron phosphate battery
Lithium iron phosphate battery, also known as “LlIFePO4 battery”, has many advantages compared with lithium cobalt oxide battery. For example, high safety, no explosion, low cost, long service life, no memory effect after long-term placement, etc. Due to its characteristics, lithium iron phosphate battery is widely used in electric vehicles and home energy storage systems.
3. Lithium manganese oxide battery
Lithium manganese oxide battery, also known as “LIMn204 battery”, is a new type of lithium battery, using metal oxide positive electrode and carbon negative electrode. Its energy density is slightly higher than that of lithium iron phosphate battery, and it is widely used in light electronic products. At the same time, lithium manganese oxide battery also has the characteristics of stable discharge, high safety, high temperature resistance, etc. However, the life of lithium manganese oxide battery is relatively short, and it can only be charged and discharged hundreds of times.
4. High nickel ternary battery
High nickel ternary battery is a kind of lithium battery that uses nickel cobalt manganese oxide positive electrode. It is widely used in new energy vehicles and other fields. In addition to high energy density, high nickel ternary battery also has the advantages of long life, good cycle performance, low internal resistance, etc., but its cost is also relatively high.
5. Graphene lithium ion battery
Graphene lithium ion battery is the latest type of lithium ion battery, using graphene negative electrode. This kind of battery has low energy consumption, long life, and high energy density of 1750mAh/g, which is much higher than other batteries. At the same time, its fast charging and discharging performance has been greatly improved, and it is considered to be an important direction for future lithium batteries.
