Since the commercialization of lithium-ion batteries

199 1 LiCoO2 was given by Sony, and the speech was great.

A substitute substance was found on both sides of the battery.

Lithium-ion batteries are widely used in

Expand the portable market. However, expansion

Their application in electric and hybrid vehicles has declined.

Recently, the development of cathode has been extensively studied.

The performance of this material is better than LiCoO2. because

Padhi et al [3] reported lithium for the first time.

Hot phosphate. Many workers concentrate on their work.

Optimization of this cathode research [4]. LiFePO4 and it

As a cathode material rod, the interest becomes because

It has good performance, safety, durability and environmental protection.

However, for large applications, this

The material must show its stability and low at a high level.

Ferrous lithium phosphate cells were obtained at low release rate under different conditions.

The temperatures are 160, 158 and 138 mAh/g, respectively.

Suitable for 60°C, 25°C and-10 c.

Fig.-1 shows plum /LiFePO4 cells in various different cells.

Temperature and dissolution rate. So, at a speed of 2 degrees Celsius,

The discharge capacities were 153.4, 136.7 and 93.5 mAh/g, respectively.

They are 60, 25 and-10 degrees Celsius respectively. Cells can be transported to

8 1%-10 c capacity, 25°C, 0.1c rate. that

The ragone diagram (Figure 2) shows good performance.
