Week 1 Understanding Different Battery Chemistry

1) materials & chemical reactions occurring at the anode and cathode of LCO, LMO, NCA, NMC, LFP and LTO type of lithium ion cells

Types of Lithium Ion Batteries

Lithium ion batteries occupy almost every household. Nearly everyone of us carries them in their cellphone. Their high energy density makes them portable and their rechargability makes them long lasting.  Lithium ion batteries  have made it possible to have aircrafts with only electric propulsion (e.g Solar Impulse aircraft). There is still along way to go before they replace the low cost lead acid batteries but research is underway across the globe.

The 5 types of Lithium ion batteries along with their properties are given below.

Lithium-Cobalt Oxide Battery

 

Used mostly in handheld electronics (Cell phones, Laptops and Cameras)
Risky especially when damaged
Cobalt is scarce and expensive
Low discharge rates
Highest energy density (110-190) Wh/kg

Lithium-Titanate Battery

Can operate at very low temp (-40°C)
Rapid charge and discharge
Used in Mitsubishi i-MiEV
Lower inherent voltage 2.4 V (compared to 3.7 V)
Lower energy density (30-110) Wh/kg

Lithium-Iron Phosphate Battery

Dramatically reduces the risks of overheating and fire.
Offers much less volumetric capacity
Used in power tools and medical equipment
Longer-life and inherently safe
Lower Energy Density (95-140) Wh/kg

Lithium-Nickel Manganese Cobalt Oxide Battery

Longer life and inherent safety
Cobalt is scarce and expensive
Less prone to heating
Used in Power tools, e-bikes and electric power trains
Lower energy density (95-130) Wh/kg

Lithium-Manganese Oxide Battery

Lower cost
Longer life and inherently safe
Used in Hybrid Vehicles, Cell phones, Laptops
High discharge rates
Lower energy density (110-120) Wh/kg
