As reported by the Reuters, head of battery cells Frank blome said on tuesday (17/march) at the car maker that VW from the next year is going to increase its Nickel content on the electric car battery from 65% now to 80%.
initially VW EV batteries contains 65% of Nickel, 20% Manganese, 15% Cobalt which is going to be increased to 10% Manganese, 10% Cobalt, 80% Nickel.
VW is stepping towards mass production of 3 million electric cars by 2025 which is equivalent to 300 Giga watt hours of energy inside the battery cells for Asian, European market.
As per blome mass productioin of battery cells will cut down the cell cost below 100$ per kWh by 2025.
VW has declared of increased Nickel content but the impact of nickel on the environment if the gets degraded or old will VW takes these old battery to its plant or just simply these batteries will be exposed to environment
lets discuss briefly about the battery technology and their chemistry's.
1. Lithium Cobalt Oxide: this technology is generally not used for EV applications because these are expensive due to its high cobalt usage and thus used in small capacity such as portable electronics.
2. Lithium Nickel Manganese Cobalt: this chemistry is cheaper and thus used for EV applications, since this chemistry includes 3 metals other than lithium, therefore there are multiple quantity combinations available keeping in mind low cobalt content for cost effectiveness.
3. Lithium iron phosphate: this is good candidate for electric bus application due to its high energy density nature.
4. Lithium Nickel Cobalt Aluminium: it has a good energy density and has affordable price and thus make perfect candidate for EV application.
5. Lithium Manganese Oxide: this was used in the nissan leaf due to its high reliability and low cost compared to other technologies.
manufacturers are trying to pack energy dense material in the cells as much as possible to become market competent but this has their own disadvantage such as cost, safety, environmental issues, and life cycle, highly energy dense battery pack could have low low life span. but lets see what prevails in the future.
