A battery is a type of lithium-ion rechargeable cell. The name “” refers to its physical dimensions: it has a 21mm diameter and 70mm length. This makes it larger than the popular battery, which measures 18mm x 65mm. While the may seem just slightly bigger, its larger size provides substantial benefits in terms of energy storage, power output, and overall performance.
The increased size of the battery means that it can hold significantly more energy compared to its smaller cousins. This results in a longer battery life per charge and improved efficiency in many high-demand devices.
One of the standout features of the is its higher capacity and energy density compared to smaller batteries. This allows it to power larger devices, such as electric vehicles and solar energy storage systems, with more reliable performance and fewer recharges.
As mentioned earlier, the battery is 21mm in diameter and 70mm in length. This cylindrical shape is the same as other lithium-ion cells, but the extra length and diameter allow for greater energy storage. To put it into perspective, a typical battery can store 5,000mAh of charge, whereas the more common battery typically holds between 2,500mAh to 3,500mAh.
This size increase directly correlates with performance improvements. Larger batteries can deliver higher discharge rates, which means that devices using batteries can consume energy at a faster rate without significantly reducing the battery’s lifespan.
It’s also worth noting that the battery is widely used in applications that require both high energy density and compact size. Its ability to deliver more power with less weight makes it perfect for energy-demanding applications like electric vehicles and power tools.
The chemistry and internal structure of a battery can vary depending on the manufacturer and its intended application. However, most cells are based on lithium-ion (Li-ion) technology, which is widely used across many types of rechargeable batteries due to its excellent energy density and long lifespan.
There are several types of lithium-ion chemistries that could be used within the format:
The internal structure of the battery consists of several key components:
While batteries come in different chemistries, they all share a similar basic structure that allows them to provide excellent performance in a wide range of applications.
The voltage of a battery typically varies between 3.6V to 3.7V when it’s in use. However, the voltage will fluctuate depending on its state of charge:
The nominal voltage of batteries makes them compatible with most devices that use lithium-ion cells, including electric vehicles, flashlights, and drones. It’s important to understand these voltage ranges when selecting chargers and other accessories.
The weight of a battery typically ranges from 50 to 70 grams, depending on the exact chemistry and the manufacturer. While this weight is heavier than that of smaller batteries, the trade-off is the higher capacity and energy density of the .
For example, an battery might weigh only about 40-50 grams, but because the holds more power, it’s heavier. This makes the battery ideal for use in larger devices that need extended run times, like electric vehicles or power tools, where every extra gram is justified by the performance improvements.
One of the key advantages of batteries is their energy density. Typically, batteries have an energy density ranging from 250 Wh/kg to 300 Wh/kg, depending on the chemistry used. This is a notable improvement compared to batteries, which usually offer around 180 Wh/kg to 250 Wh/kg.
The higher energy density of the battery allows for longer use times between charges. It also makes these batteries ideal for devices that require both power and portability. For instance, electric vehicles can use cells to store more energy in less space, resulting in longer driving ranges without increasing the size of the battery pack.
A cell refers to an individual battery unit, while a pack is a configuration of multiple cells connected in series or parallel. The pack is typically what you find in larger, power-hungry devices like electric vehicles or solar energy storage systems.
To safely operate a pack, it’s crucial to use a Battery Management System (BMS). The BMS monitors the voltage, temperature, and charge cycles of each individual cell within the pack to ensure safe operation.
The battery is used in a variety of high-demand applications, including:
The most significant difference between the and batteries is their size and capacity. The is larger (21mm x 70mm) compared to the (18mm x 65mm), and this size difference allows the to store more energy.
