Pacific Automotive Network's lithium iron phosphate battery has the advantages of high temperature resistance, high safety and stability, low price and better cycle performance. Ternary lithium battery refers to a lithium battery that uses lithium-nickel-cobalt manganate as the positive electrode material and graphite as the negative electrode material. Unlike lithium iron phosphate, lithium ternary battery has a very high voltage platform, which means that in the same case. volume Or according to weight, the specific energy and specific power of ternary lithium batteries are larger.
Lithium-ion batteries generally use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is a separator in the middle of the battery to prevent positive and negative electrodes from currentt-circuit. .
During the charging and discharging process, lithium ions travel between the positive and negative electrodes. During charging, lithium ions are deintercalated from the positive electrode and integrated into the negative electrode through the electrolyte; , lithium ions are extracted from the carbon in the lamellar structure and recombine with the positive electrode compound.
During the process of ion integration and deintercalation, an equal amount of electrons integrate and deintercalate at the same time, thereby generating an electric current.
The so-called lithium iron phosphate battery is a lithium-ion battery that only uses lithium iron phosphate as the positive electrode material. The characteristic of this type of battery is that it does not contain precious metal elements.
When it comes to batteries alone, there is no such thing as which is better or worse. This can only be applied toreal-world usage scenarios. There are different choices according to different usage situations. Let's compare the differences between the two batteries in several aspects.
EDA365 Electronic Forum 1 Safety aspects Safety aspects In the principle of lithium batteries, it is said that there is a separator in the middle of the lithium battery to prevent the positive and negative electrodes from short-circuit. the battery is pierced by a sharp object, the separator will also be pierced, so a short circuit between the positive and negative poles may cause the battery itself to heat up or even explode.
