Lithium battery classification: According to the practical performance of lithium batteries, they can be divided into ordinary energy storage capacity type and power flow type.
Based on the practical performance of lithium batteries, they can be divided into ordinary energy storage capacity type and power flow type. The power multiplier type has the characteristics of high density and high output power. High-rate batteries are increasing in size with the advent of hybrid electric vehicles. It requires the battery to store high kinetic energy, which can be applied to the distance of pure electric vehicles. It also has good power output characteristics and enters the gasoline and electric hybrid mode in low power consumption mode.
Cylindrical batteries such as 18650 cancan be divided into 3C rate and 5C rate, which means its own discharge current can reach 3 times and 5 times its own capacity. The discharge rate of high-quality 3C batteries produced by some manufacturers can even reach 5C, and those with a rate of 5C can reach 8C. The energy storage type has the characteristics of high density and large capacity and is generally used in electrical equipment that does not require high discharge current.
Lithium battery
Lithium battery is a battery that uses lithium metal or lithium alloy as anode material and uses solution non-aqueous electrolytic. The difference between lithium batteries and lithium-ion batteries is that the former is a primary battery and the latter is a rechargeable battery. Since the chemical properties of lithium metal are very active, treatmentnt, the storage and use of lithium metal has very high environmental requirements, so lithium batteries have not been used for a long time.
With the development of microelectronic technology at the end of the 20th century, the number of miniaturized devices increased day by day, placing high demands on power supplies which then entered a production phase in large scale. convenient use.
About 3c
Another power point depends on the output power, because the output voltage of 21V is relatively high , even if the current is not large enough, it can be supplemented by a voltage, so we can't just say if their power is the same, it also depends on how well their load can handle the voltage.
It can be used as a power tool battery. In addition to ordinary capacity batteriese, lithium batteries also have a type called power rate type. The difference with ordinary capacity batteries is that they have a higher discharge and are. marked with a C.
Common 18650 batteries include 3C, 5C, 10C, etc. So what does C mean? C refers to the discharge current of the battery, such as an 18650 battery cell with a capacity of 2500 mAh. 1C discharge refers to the discharge of 1 times the battery capacity, which is 2.5A, while 3C refers to the discharge current 3 times the battery capacity. is 7.5A current and 5C is 12.5A current. 3C and 5C batteries are power batteries and are often used in high-power equipment such as power tools, electric vehicle batteries and chainsaws.
