To reduce CO2 emissions and health risks from particulate and exhaust emissions, and to achieve energy independence, several countries and municipalities have announced plans to phase out internal combustion engines in favor of electric vehicles (EVs). However, high cost of battery manufacturing hinders the adoption of the new technology. The battery pack is one of the most expensive parts of the EV powertrain. It requires a more efficient manufacturing technology to reduce the overall cost.
