Sandia testing method yields pathway to better, longer-lasting solid-state batteries

Green Car Congress

The contributions from ions, electrons, and interfaces are deconvolved by correlating the CPD profiles with Li-concentration profiles and by comparisons with first-principles-informed modeling. In our case, it really has to do a lot with how fast lithium ions can move in the Si anode used in the study.

UCL, UI researchers devise method to optimize magnesium chromium oxide cathode materials; disordered materials

Green Car Congress

University College London and University of Illinois at Chicago researchers report a new, scalable method for making a material that can reversibly store magnesium ions at high-voltage. One factor limiting lithium-ion batteries is the anode. —Professor Jordi Cabana (University of Illinois at Chicago).

Rice University researchers develop inexpensive silicon-based anode for Li-ion batteries with good capacity and cycle life

Green Car Congress

Comparison of the discharge capacity and coulombic efficiency of MPSPs/PPAN anodes at various ratios versus cycle number. The new anode material can achieve more than 1,000 mAh/g capacity over more than 600 charge-discharge cycles. After being mixed with polyacrylonitrile (PAN) and pyrolyzed, MPSPs can alloy with lithium.
