Development Trend of Lithium-ion Battery


1) Polymer

Polymer lithium-ion battery is developed on the basis of liquid lithium-ion battery, with conductive material as the positive electrode and carbon material as the negative electrode. The electrolyte consists of a solid or gel organic conductive film, and the outer packaging is the latest version of aluminum plastic film. Due to more stable performance, it is also regarded as a replacement of liquid lithium-ion battery. Many companies are developing this new type of battery.

2)Power source

Strictly speaking, power lithium-ion battery is a lithium-ion battery with a capacity of 3AH or more. It generally refers to lithium-ion batteries that can be discharged to drive equipment, vehicles, etc. The battery capacity may not reach the unit AH level. Power lithium-ion batteries are divided into two types of high-capacity and high-power. High-capacity batteries can be used for power tools, bicycles, scooters, mining lamps, medical devices, etc.; high-power batteries are mainly used in hybrid vehicles and other applications that require high-current charging and discharging. According to the different internal materials, power lithium-ion batteries are divided into liquid power lithium-ion batteries and polymer ion power batteries, collectively known as power lithium-ion batteries.


3) High performance

In order to break the storage bottleneck of traditional lithium batteries, a new type of iron-carbon storage material has been developed, which can store more power in a small storage cell. However, the obvious disadvantage of this material is that the charging cycle is unstable, and the storage capacity of the battery decreases significantly after multiple charging and discharging. For this reason, a new synthetic method was used. They mixed several raw materials with lithium salts and heated them in order to create a new nanostructured material with carbon nanotubes. In one fell swoop, this method created storage cells and conductive circuits on a nanoscale material.


This stable iron-carbon material has twice the electrical storage capacity of existing storage materials, with a simple, low-cost production process that maintains its high performance over time. If the full potential of this new material can be realized, the storage density of future lithium-ion batteries can be increased by a factor of five.
