GM partners with startup SolidEnergy Systems to pack more energy in its batteries

GM’s venture arm invested in battery startup SolidEnergy Methods five decades in the past. Now, GM is tapping the MIT spinoff to help it pack additional electricity into its batteries, the most recent in a string of moves by the automaker aimed at accelerating its change to electric cars.

GM president Mark Reuss, who introduced the partnership Thursday at a Washington Put up Live conference, explained the do the job with SolidEnergy Programs to increase the strength density of lithium-ion batteries will with any luck , drive mass adoption of EVs. As element of the settlement, the two companies approach to establish a prototyping facility in Woburn, Mass., aiming to have a substantial-capability, pre-manufacturing battery by 2023. 

SolidEnergy Devices, or SES, has made an “anode-free” lithium steel battery that enhances general lifetime. According to MIT, substance improvements in SES’s batteries make them 2 times as strength-dense while retaining security comparable to the lithium-ion batteries used in present day smartphones, EVs, wearables, drones and other units. The guarantee of decrease pounds and smaller dimensions would be a unique boon for electric autos, which are inclined to be unbelievably weighty for their sizing and need to deal with the packaging constraints inherent with battery packs. 

That technology, mixed with GM’s personal IP, could give the automaker a competitive edge around Tesla, the automaker with the most affordable lithium battery cells and EV battery packs, in accordance to a new report from Cairn Strength Investigate Advisors. 

“We presently have a lot of vital IP in regards to lithium steel batteries with 49 patents granted and another 45 pending,” explained GM spokesperson Philip Leinert. “The perform we’re likely to do with SES in regards to lithium battery prototypes will aid accelerate that get the job done.”

GM has grand ambitions for EVs. The business plans to introduce 3 EVs globally by 2025 and sell only EVs by 2035. 

GM’s announcement comes just one year just after the enterprise exposed its Ultium battery system — the batteries, cells, modules, push units and electrical power electronics that are the heart of its EV approach. The Ultium system will be used in a broad range of EVs across its Cadillac, Buick, Chevrolet and GMC makes, as very well as the Cruise Origin autonomous shuttle that was revealed in January 2020. The all-electric powered GMC Hummer EV, which really should go into generation at the conclusion of the calendar year, will be the initially auto to be created with the initial-technology Ultium batteries.

Reuss also mentioned breakthroughs with GM’s following-generation of Ultium batteries. He didn’t supply details, but GM aims to force efficiency even though slashing charges. By mid ten years, the organization would like to raise the electrical power density twofold and minimize the charge of the batteries by 60%, and they are hoping the partnership with SES will support them get there.

“Affordability and assortment are two big limitations to mass EV adoption,” reported Reuss. “With this next-generation Ultium chemistry, we imagine we’re on the cusp of a once-in-a-era enhancement in electrical power density and charge. There’s even a lot more place to increase in equally types, and we intend to innovate a lot quicker than any other business in this place.”

This isn’t GM’s only undertaking into the entire world of battery growth. The firm invested $3.2 million in stable-condition battery corporation Sakti3 back in 2010, and is now in talks to construct a second large battery factory in the United States.
