Samsung SDI and Ford announced their partnership for developing a new type of hybrid Li-ion batteries which would be 40 percent lighter than nickel-metal-hydride batteries that are used currently.
The new concept will utilize the battery technology of both Lithium-ion and Lead-Acid batteries for usage in start-stop engines and for better battery life. Lead-acid batteries have a low life and the Lithium-ion technology would increase its efficiency. Samsung and Ford mentioned that the new battery will be ultra-lightweight when compared with the present 10lbs of battery weight. Ford would use the technology in the future cars that have start-stop engines.
Kumar Galhotra, VP of engineering for product development at Ford said in a statement:
“Start-stop by definition means you have to restart the battery, you have to use the lead-acid battery all the time. But if we can have this regenerative braking and this parallel battery, you can save the lead-acids to be more effective on the start stops. Now we can use start-stops, more often so you get better fuel economy.”
The new battery concept will be 40 percent lighter than nickel based conventional batteries which will allow Ford to reduce the weight of the future cars. Ford stated that the start-stop technology has been used in 70 percent of the cars and the dual-battery system will be used in hybrid vehicles as well.
Hybrids and EV’s using the technology will see improved efficiency and the smaller batteries can be fitted under trunks, passenger seats, spare tire compartments or the cars center console. Currently Ford cannot phase out the older technology as Lithium-Ion batteries are costlier.
Ford has also unveiled a lightweight concept car using high-strength steel, magnesium and carbon-fiber which reduces the weight of a car by 30 percent when compared with a 2013 Ford Fusion. The glass in the rear-window is replaced by a lighter Polycarbonate and interiors are made of carbon-fiber.
A F-150 truck was also made lighter by 700 pound using the same materials. The two vehicles are undergoing tests for corrosion, collisions and road noise and are not fitted with dual-batteries, Ford added. Ford would also focus on developing smaller engines for the Lightweight concept without any change in the performance and hopes to replace Lead-Acid batteries with Lithium-Ion batteries in the future.
