LITHIUM ION BATTERY

About: 

• A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery. 
  
  
• Components: 
  • Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. 
    
    
  • The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell. 
    
    
  
  
  
• Working: In this, lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. 
  
  
• Application: They are one of the most popular types of rechargeable batteries for portable electronics. LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications. 
  
  
• Benefits: They have high energy density, tiny memory effect and low self-discharge. 
  
  
• Safety hazards: These batteries can pose unique safety hazards since they contain a flammable electrolyte and may be kept pressurized. A battery cell charged too quickly could cause a short circuit, leading to explosions and fires. 
  
  

Recent development:

• BHEL will be sending a team of senior officers for study of the techno-commercial issues soon. Based upon the recommendations of the team, further process towards formation of Joint Venture will be carried forward. 
  
  
• Significance: 
  • With this, India has finally taken steps into its energy security and clean energy commitment to the world. 
    
    
  • This project will bring energy independence by replacing oil imports with abundant renewable. It will also create integrated manufacturing ecosystem resulting in self-reliance and lower cost.
