The near-infrared drug is gradually accepted by doctors and patients because of its non-toxicity, convenient labeling and economical...
Why should we aim at 800 kilometers? Because this value is the highest expected value for most people's cruising range, if the electric vehicle's cruising range can't reach 800 kilometers, and the cost can be accepted by most people, the electric vehicle will have less popularity. So, we set this value to the goal of our Battery 500 project. The project began in 2009 and is dominated by the Almaden Research Center. Since then, IBM has conducted this research with a number of...
