The difference between polymer lithium battery and lithium cobalt oxide battery

- Oct 28, 2019-

First, the characteristics are different


1, polymer lithium battery: shaping flexibility; higher mass specific energy (3 times MH-Ni battery); electrochemical stability window width, up to 5V; perfect safety and reliability; longer cycle life, capacity Less loss; high volume utilization.


2. Lithium cobaltate lithium battery: stable structure, high capacity ratio and outstanding comprehensive performance, but its safety is poor and the cost is very high.


Second, the application is different


1. Polymer lithium battery: Polymer lithium ion battery has been matured and commercialized in the world for more than 2 years. Although the sales volume is growing rapidly, its market share is still around 10%, and liquid lithium battery market share is 90%. Unable to compare, lower than people expected.


2, lithium cobalt oxide battery: the application of lithium cobalt oxide battery is still relatively small, the technology of cobalt lithium for small batteries is very mature, but now the cost of cobalt lithium is too high, many companies use manganese lithium instead, and some are Manganese lithium.


Lithium cobaltate has stable performance. Currently, the technology used in mobile phones is the most mature, but the biggest disadvantage of application is high cost. Cobalt is a scarce strategic metal. In addition, it is also difficult to apply to power batteries.
