Lyten has made progress in stretching the lifetime of its batteries, not too long ago seeing some samples attain as excessive as 300 cycles, Mickolajczak says. She attributes the success to Lyten’s 3D graphene materials, which helps forestall undesirable aspect reactions and enhance the cell’s vitality density. The corporate can also be trying to make use of 3D graphene, a extra sophisticated construction than the two-dimensional selection, in different merchandise like sensors and composites.  

Even with latest progress, Lyten continues to be removed from producing batteries that may final lengthy sufficient to energy an EV. Within the meantime, the corporate plans to carry its cells to market in locations the place lifetime isn’t fairly so vital. 

Since lithium-sulfur batteries may be extraordinarily light-weight, the corporate is working with clients constructing gadgets like drones, for which changing the batteries ceaselessly could be definitely worth the financial savings on weight, says Keith Norman, Lyten’s chief sustainability officer. 

The corporate opened a pilot manufacturing line in 2023 with a most capability of 200,000 cells yearly. It not too long ago started producing a small variety of cells, that are scheduled for supply to paying clients later this yr. 

The corporate hasn’t publicly shared which corporations will obtain the primary batteries.  Shifting ahead, two of the corporate’s major focuses are bettering lifetime and scaling manufacturing of each 3D graphene and battery cells, Norman says. 

The street to lithium-sulfur batteries that may energy EVs continues to be a protracted one, however as Mikolajczak factors out, at present’s staple chemistry, lithium-ion, has improved leaps and bounds on value, lifetime, and vitality density within the years that corporations have been working to tweak it. 

Individuals have tried out an enormous vary of chemistry choices in batteries, Mikolajczak says. “To make one in all them actuality requires that you simply put within the work.”
