MIT/Tsinghua high-rate aluminum yolk-shell nanoparticle anode for Li-ion battery with long cycle life and high capacity

Green Car Congress

A team of researchers at MIT and Tsinghua University has developed a high-rate, high-capacity and long-lived anode for Li-ion batteries comprising a yolk-shell nanocomposite of aluminum core (30 nm in diameter) and TiO 2 shell (~3 nm in thickness), with a tunable interspace (Al@TiO 2 , or ATO). —Li et al.

Capstone Receives order for 34 microturbines for Denver RTD electric bus fleet

Green Car Congress

The DesignLine range-extended electric buses are 45 feet long, and feature an all-electric drivetrain using Li-ion batteries for energy storage. The lithium-ion batteries recover kinetic energy from the bus brakes via a regenerative braking system to extend the range.

135. ENERGY DENSITY: GETTING TO LONGER DRIVING RANGES

Qnovo

A common denominator is the battery’s energy density : it is the amount of electrical energy per unit volume (or per unit weight) that a rechargeable battery can store. State-of-the-art energy density figures for lithium-ion batteries stand today near 700 Wh/l and 300 Wh/kg. Energy is measured in units of kWh.
