A simple switch of tape could keep batteries from self-discharging

It never fails … you go to use a device that should be fully charged, but its battery has gone flat over time. Such may soon no longer be the case, however, if battery manufacturers simply start using a different type of adhesive tape.Continue ReadingC… Continue reading A simple switch of tape could keep batteries from self-discharging

World-first Dutch program will use ride-share cars as a grid battery

Renewable energy grids need lots of energy storage – and EVs plugged into charging stations represent a huge, city-wide battery just waiting to help out. The Dutch city of Utrecht is about to pioneer a clever way to kickstart two-way charging.Continue … Continue reading World-first Dutch program will use ride-share cars as a grid battery

Fast, low-cost direct lithium extraction could avert a supply crisis

Canadian company Volt Lithium has developed and pilot-tested a new low-cost lithium extraction method to pull this critical battery metal out of low-concentration brines. Now it plans to turn old oil fields into lithium production operations.Continue R… Continue reading Fast, low-cost direct lithium extraction could avert a supply crisis

Chinese scientists push lithium batteries up to a record 711 Wh/kg

Tesla’s 4680 cells, for comparison, measure somewhere between 244-296 Wh/kg. So the extreme-density cells recently tested in Beijing represent a huge leap forward from the status quo – even if they’re solely focused on maximizing a single metric.Contin… Continue reading Chinese scientists push lithium batteries up to a record 711 Wh/kg

Simple tweak creates safer, more efficient solid-state batteries

Oak Ridge National Laboratory (ORNL) has come up with a small tweak that could have big consequences. By making a small change to how a type of solid-state battery is made, the scientists managed to eliminate defects in the electrolyte film, opening th… Continue reading Simple tweak creates safer, more efficient solid-state batteries
