Lithium Ion batteries provide high performance and fast recharging, making them ideal for electric vehicles. However, their cost has always been a barrier to adoption in the world of electric vehicles. Tesla has sidestepped this issue by adopting a highly scalable modular approach. Every battery package they construct is made out of hundreds of one single standard cell. Tesla is taking their battery production in-house, constructing the Gigafactory to build this one battery unit in high volumes. Through this simplified approach, they’ve been able to not only bring better battery technology to electric vehicles but have also vertically integrated their manufacturing.
