Maxwell’s battery technology to power Tesla cars

Electric car maker Tesla motors is in a $218 all-stock million deal to buy US battery-maker Maxwell Technologies. The car manufacturer hopes the purchase will improve car performance and help reduce prices.

The purchase caught the attention of scientists and EV aficionados, including Fred Lambert, writing for Electrek, who says that Maxwell’s technology could provide Tesla cars with longer range and more durability and power.

In a paper published last year, Maxwell’s lead chemists and battery scientists described their coating technology:

“Unlike conventional slurry cast wet coated electrode, Maxwell’s DBE offers significantly high loading and produces a thick electrode that allows for high energy density cells without compromising physical properties and electrochemical performance. Maxwell’s DBE exhibits better discharge rate capability than those of wet coated electrode. Maxwell has demonstrated scalability by producing robust self supporting dry coated electrode film in roll form with excellent long-term electrochemical cycle performance, and established large pouch cell prototypes in greater than 10Ah format.”

The purchase has been approved by Maxwell’s board and the companies aim for the deal to close in the second quarter of 2019.
