KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

The researchers made an anode from the laser-scribed material and tested it in a lithium-ion battery over 1000 charge-discharge cycles. With the nanodots in place, the material had a four-fold higher electrical storage capacity than the original MXene and almost reached the theoretical maximum capacity of graphite. Alhajji, E.,

New cathodes for low-temperature solid-oxide fuel cells

Green Car Congress

An SOFC has three major components: two porous electrodes (cathode and anode) separated by a solid oxygen ion (O 2– ) conducting electrolyte. However, solid oxide fuel cells (SOFCs) can oxidize any fuel, because the electrolyte transports an oxygen ion. Earlier post.). 2015.06.136.

ANL Project on Actively Coupled Ultracapacitor-Battery System for PHEVs Attracting OEM Interest

Green Car Congress

The objective of the project is to develop a high power and high energy electrical storage system that combines the strengths of each technology—high power density for ultracapacitors and high energy storage for Li-ion batteries—at equal or better system efficiency and net cost/density compared to current conventional Li-ion batteries.
