Improving Battery Capacity

A new printing technology is in development that promises to pack between 10 and 30 percent more energy into batteries for electric vehicles helping them to compete with conventional cars.

There is more at stake in battery development than longer-lasting AAs. In order for electric vehicles to compete with conventional models, car batteries must be cheaper, i.e. more efficient: "If the batteries could store more energy, automakers could use fewer of them, thus saving money. In conventional lithium-ion-battery manufacturing, electrode materials are applied in the form of slurry to metal foils. The thickness of the electrode is limited by the rate at which lithium ions can diffuse out of the material to reach an electrolyte."

  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
