World's fastest manufacture of battery electrodes

Thu, 23 Oct 2014 09:10:02 EDT

New world record: Scientists have increased the manufacturing speed of electrode foils coated batch-wise by a factor of three – to 100 meters per minute. This was achieved by a flexible slot die process that enables production of any pattern with high precision and at high speeds. Thanks to the patented new technology, electrode foil production speed is increased by a factor of 3. As a result, lithium-ion batteries can be manufactured at much lower costs.<img src="" height="1" width="1"/>

Study sheds new light on why batteries go bad

Sun, 14 Sep 2014 15:52:16 EDT

A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.<img src="" height="1" width="1"/>
