Lithium iron phosphate batteries are high -tech products with many chemical
raw materials and complicated craftsmanship. Its production environment has high
requirements for temperature, humidity, dust, etc. If it is not controlled, the
battery quality will fluctuate.
2. Poor electrical conductivity and slow lithium ion diffusion speed
When the high power is charged and discharged, the actual capacity is lower
than the capacity. This problem is a difficult point to restrict the development
of the lithium iron phosphate industry. The reason why lithium iron phosphate
began to be widely used so late is a major problem.
3. The influence of materials
The electronic conductivity of lithium iron phosphate itself is poor, and
it is easier to generate polarization and reduce the performance of the
capacity; the negative electrode is mainly low -temperature charging because it
will affect the problem of safety; Increasing, lithium -ion migration impedance
will increase; the fourth is binder, which has a greater impact on the low
temperature performance of the battery.
