LR6 alkaline battery

What is the difference between LR6 alkaline battery power LR6 alkaline battery and energy storage technology battery?

1. Working voltage and size are different

Lithium-ion battery manufacturing companies found that in the battery field, when the working voltage rises, the corresponding output voltage will also rise, so that the power lithium-ion battery pack can handle some high-power equipment; and the direct impact of the series connection method is The current capacity of the entire battery pack is increased, and the capacity is affected by it. E output current, so the direct effect of series connection is to make the lithium-ion battery pack. As the capacity increases, the capacity of batteries connected in this way tends to be larger, which is the so-called capacity lithium-ion battery.

Power lithium batteries are mainly used for energy storage, with large capacity requirements and long service life requirements, while lithium-ion batteries have a short service life. The battery for pneumatic tools is small in size and does not need to provide a high-power output, while the battery mainly provides power and requires a high-power output.

2. The products used are different

Some large and medium-sized equipment require a higher working voltage. Since low-power batteries cannot work, power lithium-ion batteries are chosen. For example, when we generally use electric vehicles, we generally need a working voltage of 48V. Compared with some situations in our daily lives, 48V is not very large. Therefore, power lithium-ion batteries must be used to ensure the operation of electric vehicles. We usually go to some shopping malls or shopping malls with some sign lights and backup power. Since the power consumption of these equipment is not very large, we usually use loose lithium-ion batteries, which is different in the use of the product. of.

The lithium-ion batteries used in BYD's power trams and new energy vehicles are power lithium batteries, which are divided into three types according to their characteristics: switching power supply types, electric energy types, and switching power supply and electric energy types. The important feature of power lithium-ion batteries is that they are suitable for charging batteries with polymer cells, generally reaching 10C, and the basic parameters are special purposes (W/kg). The key feature of kinetic energy types is higher energy density (WH/kg). For example, the volume type is for marathon runners, which requires physical strength, that is, it has a large volume, and generally does not require large current charging and discharging characteristics; the output type is for weightlifters, who fight for bursts and also need physical strength, otherwise the volume is very small and they can run very close.

3. The internal resistance is different

The internal resistance of power lithium-ion batteries is smaller than that of large-capacity lithium-ion batteries. Taking 18650 as an example, manufacturers with a good 3-time charge and discharge rate generally have a PDC with an internal resistance of about 40. Manufacturers with a 5-time charge and discharge rate generally do not have a PDC with an internal resistance of about 20%.
