The evolution in the battery industry and especially in the field of Li-ion battery is the development of flexible Li-ion battery.

Flexible Li-ion Batteries

In a Li-ion battery, the lithium ions (Li+) are the most critical component, and the same is for a flexible Li-ion battery. During a discharge cycle, lithium atoms are ionized, and they move towards the cathode via the electrolyte. There are different types of Li-ion batteries, and the most common one is the lithium cobaltate batteries made from lithium carbonate and cobalt. They have a cobalt oxide cathode and use graphite carbon as their anode material. The vast majority of lithium-ion batteries use graphite powder as an anode material.. The cathode material in the battery decides the major performance of Li-ion batteries. In addition, lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate are commonly used by the manufacturers. The electrolyte in Li-ion batteries is an organic solvent with lithium salts.

The Li-ion battery has advantages over other batteries, such as:

  • High volumetricenergy density
  • High current, voltage and capacity
  • Low requirementfor routine maintenance
  • No memory effect
  • Low self-discharge
  • Long lifespan
  • Environmentally friendly


Why Flexible Li-Ion Batteries Are Becoming a Better Choice For 3C Digital Devices?

Flexible Li-Ion Batteries

There has been a rising demand for 3C digital devices and consumer electronics, which all needs to be powered by batteries. At present, the Li-ion batteries are widely used in these fields:

  • Portable Electronic Devices: The rechargeable Li-ion batteries are the popular choice for portable electronic devices like smartphone, laptop, tablet, and smart wearable devices.
  • Energy Storage: Combining solar and wind power with Li-ion batterieshas made it possible to store the renewable energy generated. Lithium-ion batteries are also used in emergency power backup, UPS  and solar generators/portable power stations/power bank.


Flexible Li-ion batteries are still at the early stage of development but the future of flexible Li-ion batteries is promising. These batteries are used for wearable devices, intelligent electronics, and roll up displays. The flexible batteries or flexible Li-ion batteries have the following characteristics:

  • Bendable
  • Twistable
  • Lightweight
  • Stretchable
  • Implantable

Flexible Li-ion batteries can be used in 3C devices including:
