The chemical reaction mechanisms are different.
1. Zinc-manganese alkaline battery: Zinc-manganese alkaline battery is a common dry cell battery. Its positive electrode uses manganese oxide and the negative electrode uses zinc during the discharge process, the zinc will be oxidized to Zn; (OH)2, generating electrons and hydrogen ions at the same time; During the charging process, hydrogen ions and electrons will gather on the electrode surface to form hydrogen gas because hydrogen gas escapes easily, it is difficult for alkaline zinc; manganese batteries to charge and discharge stably, and are not suitable for use as secondary batteries.
2. Lithium battery: Lithium battery uses lithium salt as the positive electrode material. During the discharge process, lithium ions move from the positive electrode to the negative electrode, releasing electricity.ctrons to complete the conversion of electrical energy; during the charging process, the lithium ions then return from the negative electrode to the positive electrode and store the electrons; because the cathode material of lithium batteries is relatively sensitive to moisture and oxidation, contains volatile organic compounds, and generates heat and gases during discharge. , these factors limit the lifespan and safety performance of lithium batteries.
Lithium iron phosphate batteries seem to be very good, but in fact the quality of this battery is not very good, and it is easy to lose power, so when the use of electric vehicles, this type of battery Lithium batteries are not recognized by everyone. Additionally, this type of battery has a relatively short lifespan and is very difficult to maintain, which is why many people are not optimistic about this ttype of battery.
Lithium iron phosphate batteries are generally very difficult to charge in many cases. This will cause problems for people who ride electric bicycles, so this type of battery is very impractical and has been abandoned by everyone. The electrical capacity of the ternary lithium battery is still very strong. During long-term use, people have also praised this battery. This shows that the ternary lithium battery is a very good battery. This may become common in the future. Of course, judging from the current situation, a market mechanism has not yet been formed, but since it is more convenient to use, it will definitely be recognized by everyone in the future. in the future. We must therefore trust ternary lithium-ion batteries.
