The reason is that batteries with different voltages have different characteristics.
1. Both 3.6V and 3.7V lithium polymer batteries are lithium polymer batteries. The upper limit of lithium polymer batteries is 4.2, the lower limit is 2.6, and the general standard is 3.7V.
2. The 3.2V lithium iron phosphate battery can discharge to a large capacity. This type of battery is now used in electric vehicles. This type of battery has a long lifespan and is lightweight.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Detailed information:
Battery main electrode materials:
1. Carbon anode material: has been actually uused in lithium-ion. batteries Negative electrode materials are mainly carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc.
2. Negative tin electrode materials: can be divided into two types: tin oxide and composite tin oxide. Oxides refer to oxides of metallic tin in various valence states. There are no commercial products.
3. Alloys: including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, and there are no commercial alloys. some products.
4. Nano-oxide: nano-titanium oxide and nano-silicon oxide are added to traditional graphite, ox nanotubesyde of tin and carbon, which significantly improves the charging and discharging capacity and the number of charging and discharging. time of lithium batteries.

You are asking how much extra power a 3.7 volt battery has compared to a 3.2 volt battery ? 0.55 volts. According to the query of People's Daily online, the voltage of 3.2V lithium battery is 3.65V and the voltage of 3.7V lithium battery is 4.2V. The difference between two is 0.55 V. Battery refers to a cup, tank or other container or part of a composite container containing an electrolyte solution and metal electrodes to generate electric current. It is a device capable of converting chemical energy into electrical energy.
