Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. —Prof. Haesun Park, Chung-Ang University, co-corresponding author.

ARPA-E RANGE: $20M for robust transformational energy storage systems for EVs; 3x the range at 1/3 the cost

Green Car Congress

The Robust Affordable Next Generation EV-Storage (RANGE) program’s goal is to enable a 3X increase in electric vehicle range (from ~80 to ~240 miles per charge) with a simultaneous price reduction of > 1/3 (to ~ $30,000). ARPA-E defines robust design as electrochemical energy storage chemistries and/or architectures (i.e.

New high conductivity composite solid electrolyte for solid-state Li batteries

Green Car Congress

Korea have developed a new composite solid electrolyte that shows very high total conductivity (9.4 × 10- 4 S cm -1 ) at room temperaturefor all-solid-state lithium batteries. The new composite combines Li 1+x Al x Ti 2-x (PO 4 ) 3 (LATP) with a NASICON (Na superionic conductor)-like structure with Bi 2 O 3.

New Berkeley Lab spectroscopy technique for in situ measurement of charge dynamics in an operating battery electrode

Green Car Congress

Windows etched into a foil covering allow soft X-rays to measure charge dynamics in an operating electrode. Researchers at Berkeley Lab and its Advanced Light Source have developed a new soft X-ray spectroscopy technique that can measure the migration of ions and electrons in an integrated, operating battery electrode.
