3D graphene boosts new batteries beyond lithium-ion

Lyten, a Silicon Valley materials company, aims to displace the incumbent lithium-ion (Li-ion) cell chemistry from mainstream electrified vehicle (EV) applications using lithium-sulfur (Li-S) technology. “Our current generation materials perform at an almost 2.5X rate over conventional Li-ion batteries,” Dan Cook, Lyten's president and CEO, told SAE Media.

The technology enabler is the San Jose, California-based company's invention of three-dimensional (3D) graphene versus traditional two-dimensional (2D) graphene, in which an allotrope of carbon consisting of a single layer of atoms is arranged in a flat, 2D honeycomb lattice nanostructure.
