Lithium Polymer Battery in Consumer Devices

Lithium polymer battery, also known as LiPo battery, is a rechargeable battery that uses lithium-ion technology. It is a lightweight and high-energy-density battery that is commonly used in consumer electronics, such as smartphones, tablets, and laptops. The lithium polymer battery was first introduced in the 1970s, but it was not until the 1990s that it became commercially available. The first lithium polymer battery was used in portable radios and was later used in mobile phones. Since then, the technology has advanced, and lithium polymer batteries are now used in a wide range of consumer electronics. Consumer electronics have become an integral part of our daily lives, and lithium polymer batteries play a crucial role in powering these devices. The high energy density and lightweight nature of lithium polymer batteries make them ideal for use in portable devices. They also have a low self-discharge rate, which means they can retain their charge for a longer period of time.

Advantages of lithium polymer battery

  • High energy density

Lithium polymer batteries have a high energy density, which means they can store a large amount of energy in a small space. This makes them ideal for use in portable devices, where space is limited.

  • Lightweight and compact

Lithium polymer batteries are lightweight and compact, making them ideal for use in portable devices. They are also thinner than other types of batteries, which allows for a more compact design of consumer electronics.

  • Low self-discharge rate

Lithium polymer batteries have a low self-discharge rate, which means they can retain their charge for a longer period of time. This is important for portable devices that may not be used for extended periods of time.

  • Flexible and customizable shape

Lithium polymer batteries can be made in a variety of shapes and sizes, making them flexible and customizable. This allows for a more efficient use of space in consumer electronics.

  • Fast charging time

Lithium polymer batteries have a fast charging time, which means they can be charged quickly. This is important for portable devices that may need to be charged quickly.

Safety Concerns of Lithium Polymer Battery

OVERCHARGING–Overcharging a lithium polymer battery can cause it to overheat and potentially catch fire. It is important to use a charger that is specifically designed for the battery being used.

SHORT CIRCUITING–Short-circuiting a lithium polymer battery can also cause it to overheat and potentially catch fire. It is important to use the battery in the device it was designed for and not to modify or alter the battery in any way.

THERMAL RUNAWAY–Thermal runaway occurs when a lithium polymer battery overheats and the temperature continues to rise, causing a chain reaction that can lead to an explosion. This can be caused by overcharging, short-circuiting, or physical damage to the battery.

PROPER STORAGE AND DISPOSAL–Lithium polymer batteries should be stored in a cool, dry place and disposed of properly. Improper disposal of lithium polymer batteries can lead to environmental damage.

All in all, Lithium polymer batteries have a high energy density, are lightweight and compact, have a low self-discharge rate, are flexible and customizable, and have a fast charging time. They are commonly used in smartphones, tablets, laptops, wearable devices, electronic toys, and electric vehicles. It is important to use lithium polymer batteries properly and follow safety measures to prevent overcharging, short-circuiting, and thermal runaway. Advancements in technology and improved safety measures will continue to be made, and lithium polymer batteries have the potential to be used for renewable energy storage.

FAQ about Lipo Battery Cell

  • What is Lithium Polymer Battery?
  • Lithium Polymer Battery, (commonly short for LiPo, LIP, Li-poly ), is a rechargeable lithium-ion battery using a polymer electrolyte instead of liquid electrolyte, which makes it less powerful when there is leak or explosion. LiPo cells are now widely used in tablets, mobile phones MP4 and other wireless devices.
  • Which is Better Lithium ion or Lithium Polymer Battery?
  • As far as end user is concerned, lithium polymer battery(LIP) is essentially much better then lithium-ion battery (LIB).LIP has higher energy density then LIB, what’s more LIP is much safer then LIB, LIB can easily make explosion when short cut or over charged etc, while LIP has no such problem, LIP will simply Expand and blow and no explosion for most of the time.For New devices like Bluetooth or some medical device that require unique design of shape, LIP can be of great value, there is curved batteries and super thin battery cells among LIP manufacturer.
  • What is a 3s 5s LiPo?
  • Fo battery pack that contain 3 or 5 cells connected in series, they are called 3s or 5s LiPo batteries. A 3S battery has 11.1 volts(some like to call it 12V), and a 5S battery has 18.5 volts. but we know a single cell capacity is limited, so people will use more cell to parallel and get more capacity(also call Ah)So 3s2p is 6 cell in total, suppose each cell 3.7v 2000mah a 3s2p pack is 11.1v 4000mah in total, plus extra PCBA size, so you can have a rough idea of what pack you will need
  • What does the 10C mean in Lipos? What is C rate anyway?
  • People use C Rate to define a discharge rate. Most Lipo batteries will say on its description something like “10C to 20C”. This means that 10C is the nominal discharge rate and 20C is the maximum discharge rate.It’s common to use mah to define battery capacity. A battery with a 2000 mAh capacity can deliver 2 Ampere ( usually short for 2000 mA/2A, 2A=2000 ma) for 1 hour. to make it more clear, it can also send power in 200 mA for 10 hours. The battery capacity, together with the LiPo battery’s discharge rate will define its maximum current output (Ampere, A).A 3S 2000 maH 10C LiPo pack will get you this: 2000 mAh x 10C = 20.000 mAh discharge rate 20.000 mAh / 1000 = 20 A constant discharge rate.So if your projects requires constant discharging rate higher then 20A, you will need to choose another battery pack, always check with the motor description or product description when you select the battery cells.
