Electric vehicles

Lithium-ion is the winning type of rechargeable battery for the decade - there is almost a consensus. You can count about 150 manufacturers of these and IDTechEx has profiled nearly all of them.

Trains can return up to 30% of their kinetic energy when braking, whether they are electric or conventional. SEPTA has unveiled its recycled energy and optimization project

KBMJ partners to acquire ¥20.0 billion equity stake to support global growth of KBMJ's unique, industry leading lithium-ion battery technology

Electric vehicles are not green just because they use electricity rather than fuel, but their green credentials critically depend on the materials used, the driving conditions and, most importantly, the carbon intensity of their electricity sources.

The city of Hangzhou in China is placing one of the largest single orders for EVs in China or indeed the world.

Green Automotive Company has has purchased UK-based Liberty Electric Cars, for an undisclosed amount.

Rice University, Lockheed Martin researchers extract multiple anodes from a single wafer for lithium-ion batteries

Daikin Industries will soon start making electrolytes for lithium ion batteries and begin selling them in January

Increases will be valid up to end-2012; country to install more charging stations

BASF granted usage license for vinylene carbonate in lithium-ion batteries from Mitsubishi Chemical Corporation.

The proprietary system that makes it possible to wirelessly transfer energy over long distances using laser light to create a continual source of power.

Brammo Inc., a leading developer of electric vehicle technology and manufacturer of distinctive two-wheel electric vehicles, has closed the first $13 million tranche of a $45 million Series C funding round designed to accelerate the company's development plans.
