Types of Li-ion Batteries

Li-ion Battery Components

A typical cylindrical battery structure includes:case, cap, a positive electrode, a negative electrode, separator, electrolyte, PTC element, gasket, anti-explosive valve, etc. Generally, the battery case is the negative electrode of the battery, and the cap is the positive electrode of the battery. The battery case is made of a nickel-steel plate.

Li-ion Battery Advantages

  •  Lithium-ion batteries energy density is as high as 120~190Wh/kg

  •  Lithium-ion battery discharge cut off voltage is 2.5V, full charge voltage is 4.2V

  • unlike Ni-Cd and Ni-MH batteries, Lithium-ion batteries don't have memory effect.

  • The average lithium-ion battery lifespan for a large-capacity battery pack can be as long as eight or more years. 

  • compare with lead-acid batteries, lithium-ion batteries have significant environmental benefits. It can be recycled.

  •  high density and voltage have the battery packs with lighter weight than similar spec lead acid, Ni-MH and Ni-Cd battery packs

  •  Lithium batteries has low self-discharge rate

  • lithium-ion batteries have developed for a long time with a high degree of standardization, automatic and mass continuous production reduced the costs.

Lithium Battery Applications

Most of PLS li ion cells are 18650 models, 18650 is the gasoline of the 21st century, which is widely used for portable communications, zero-emissions vehicles, military equipment, backup power supply, etc., like electronic cigarette, power tools, robotics, and other electronic devices. With the mature production technology and high standardization, meanwhile, the fully automatic production line guarantee low costs and good quality of battery cells.

FAQs Of Li-ion Batteries

What Are Possibly The Reasons Cause Cells Or Battery Packages Non-rechargeable?
  • Zero Voltage in cell or cell in battery packages.

  • Wrong battery connection, or abnormity inner parts or circuit protector

  • Charger is the failure to the output current.

  • External factors can be possible triggers of meager charge rate (e.g., extremely low or high temperatures).

Is The Ambient Temperature Important When Charging?

Yes. Ideally, batteries should be recharged at room temperature. We recommend maintaining a temperature range of 15°C to 30°C.

What Is The Electrochemistry Principle Of Li-ion Battery?

Major element of Li-ion cell positive is LiCoO2, negative is mainly C. when charged

Positive reaction is: LiCoO2→Li1-xCoO2 + xLi+ + xe-

Negative reaction is: C + xLi+ + xe→CLix

Total reaction is: LiCoO2 + C→Li1-xCoO2 + CLix

The reaction is reversible as discharged.

What’s The Cycle Life Of Lithium Ion Battery?

Charging and discharging the battery as blew conditions:

0.2C standard charge to 4.2V end-off

0.2C standard discharge to 2.75V cut-off

Continuous charge and discharge for 500 cycles, the capacity will be more than 70% of initial capacity

How To Maintain Lithium Ion Batteries?

Recharge the lithium-ion batteries before it comes to discharge cut off voltage(2.75V), when use as a battery pack, please add PCB or BMS for the pack. And charge the batteries every 3months when have it in storage.
