3.7V lipo battery

　　What are the advantages of 3.7V lipo battery and what are their classifications?

　　3.7V lipo battery have the advantages of ultra-long life, no memory effect, small size, light weight, high temperature resistance, and safe use. In addition, they can be divided into lead-acid batteries, silver-zinc batteries, sodium nickel chloride batteries, iron-nickel batteries, etc. , the relevant content will be introduced in detail below.

　　1. Product advantages of 3.7V lipo battery

　　1. Super long life. The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times. The best battery cycle life of the lithium iron phosphate power battery produced can reach more than 2,000 times. Standard charging (5 hourly rate), can reach 2000 times. Lead-acid batteries of the same quality last "half a year for new ones, half a year for old ones, and another half year for maintenance", which is 1 to 1.5 years at most, while lithium iron phosphate batteries will last 7 to 8 years when used under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries. [5]

　　2. It is safe to use. Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganate will explode under strong collision and pose a threat to the life safety of consumers. Iron phosphate Lithium has undergone rigorous safety testing and will not explode even in the worst traffic accidents.

　　3. It can charge and discharge quickly with high current of 2C. Under a special charger, the battery can be fully charged within 40 minutes at 1.5C, and the starting current can reach 2C. Lead-acid batteries do not have this performance.

　　4. High temperature resistance. The electric heating peak of lithium iron phosphate can reach 350℃~500℃, while the peak value of lithium manganate and lithium cobalt oxide is only about 200℃.

　　5. Large capacity.

　　6. No memory effect.

　　7. Small size and light weight.

　　2. Classification of 3.7V lipo battery

　　1. Lead-acid battery

　　2. Nickel-cadmium battery

　　3. Nickel metal hydride battery

　　4. Iron-nickel battery

　　5. Sodium nickel chloride battery

　　6. Silver-zinc battery

　　7. Sodium-sulfur battery

　　8. Lithium battery

　　9. Air batteries (zinc air batteries, aluminum air batteries)

　　10. Fuel cell A fuel cell is a device that directly converts chemical energy into electrical energy. Its positive electrode is an oxygen electrode, and its negative electrode is a fuel electrode such as hydrogen, hydrocarbon, or ethanol. The catalyst catalyzes the reduction reaction of oxygen at the positive electrode and conducts electrons from the external circuit to the reaction site of the oxygen electrode; it catalyzes the oxidation reaction of the fuel at the negative electrode and conducts electrons from the reaction site to the external circuit; the electrolyte transports ions generated by the reaction between the fuel electrode and the oxygen electrode. and prevent the transfer of electrons. The electrons perform work through the external circuit and form an electrical loop. As long as fuel and oxygen are continuously supplied to the battery from outside the device, discharge products are continuously discharged from the device (hydrogen-oxygen fuel cell).

　　11. Solar battery

　　12. Super capacity capacitor

　　13. Flywheel battery

　　14. Sodium-sulfur battery. The theoretical specific capacity of sodium-sulfur batteries can reach 760 W?h/kg, and the actual capacity has reached 300 W?h/kg. It has a long charging mileage and a long cycle life.
