U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

Researchers from the Cockrell School of Engineering at The University of Texas at Austin have developed a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways. The cathode in their study is 89% nickel. —Wangda Li.

SJTU team develops self-healing binder for silicon microparticle anodes

Green Car Congress

Nonetheless, several technical challenges still limit its commercialization. The major problem of Si anodes is their drastic volume changes during deep cycling, which often leads to the severe pulverization, electrical contact loss, unstable solid-electrolyte interphase (SEI), and subsequent poor electrochemical cycling reversibility.

Johnson Controls study finds 97% of US consumers interested in start-stop technology in vehicles

Green Car Congress

The research was conducted to gain understanding of how consumers view fuel-saving power train technologies based on attributes such as purchase price, fuel economy, annual fuel cost and performance. The majority like the idea because of fuel cost savings, and another quarter of consumers think the idea “just makes sense.”

Stanford, SLAC team cages silicon microparticles in graphene for stable, high-energy anode for Li-ion batteries

Green Car Congress

The graphene cage acts as a mechanically strong and flexible buffer during deep cycling, allowing the silicon microparticles to expand and fracture within the cage while retaining electrical connectivity on both the particle and electrode level. —Yi Cui. Here we introduce a method to encapsulate Si microparticles (∼1–3 µm).

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. The electrode can be continuously deep cycled up to 5,000 times without significant capacity decay. Click to enlarge. At a charge/discharge current of 1.0
