This repository contains my research on what Li-ion batteries are, how they work and how i created a battery managment system for these cells must have the following components in-order to charge/discharge the li-ion battery saftely:
- Overcharge
- Over-discharge
- Discharge too quickly
li-ion batteries are highly dangerous. They can catch fire or explode if mishandled. Proceed with caution at your own risk.
Its a secret🤫, do not tell anyone. They are lithium ion batteries.
- Lithium ion battery is an advanced battery technology that uses lithium ions as key component of its electrochemical reaction.
- I will discuss about the process in detail in the respective topic guide.
- Right now just remember that the lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging.
- Lithium ion batteries are one of the highest energy dense batteries in the world today.
- They can store up to 100-265 Wh/kg or 250-670 Wh/L.
- In addition to this they can celiver upto 3.6V.
- This is 3 times higher then the Ni-Cd or Ni-Mh battery technologies.
- They can deliver large amounts of current for higher-power applications.
- Lithum Ion batteries require low maintenance
- They do not require scheduled cycling to maintain thier battery life.
- Li-ion batteries have no memory effect.
- Memory effect is a detrimental process where repeated partial discharge/charge cycles can cause a battery to "remember" a lower capacity.
- Li-ion batteries have a low self-discharge rate of 1.5-2 % per month.
- They are easily disposable because they are not made of toxic materials like cadmium.
The 18650 cells are Lithium-ion battery. Lithium-ion battery is a type of rechargeable battery.
The first prototype of the Li-ion battery was developed by Akira Yoshino. in 1985, based on the research by John Goodenough, M.Stanley Whittingham, Rachid Yazami and koichi Mizushima during 1970-1980s.
The first commercial batteries were developed by sony and Asahi Kasei team led by Yoshio Nishi in 1991. For more information click here.
Due to the advantages the li-ion batteries have displace the Ni-Cd batteries in portable electronic devices like laptops and smart phones.
These batteries are also help in millitary and aerospace applications.
