The Difference Between Galvanic Cells and Electrolytic Cells

Oxidation-reduction, or redox reactions, take place in electrochemical cells. There are two different types of electrochemical cells. Spontaneous reactions occur in galvanic (voltaic) cells, and nonspontaneous reactions occur in electrolytic cells.

Scientists Find Garnet Ceramics May be Great for High-energy Lithium Batteries

  Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered excellent properties in a garnet material that could enable development of higher-energy battery designs.   Using scanning transmission electron microscopy, the ORNL-led team were able to take an atomic-level look at a cubic garnet material called LLZO. The researchers found the material … Continue reading Scientists Find Garnet Ceramics May be Great for High-energy Lithium Batteries

New Study Shows Why Batteries Fail

  A new study shows that rapid-charging a battery and using it to provide high-power, rapidly draining power may not be as damaging as researchers had originally thought, and the benefits of slow draining and recharging may have been overestimated.   These results challenge the prevailing view that “supercharging” batteries is always harder on battery … Continue reading New Study Shows Why Batteries Fail

Developing a Longer Life Smartphone Batterys

Ever since their rise in popularity, smartphones have had one very significant flaw. Battery life. This problem has lead to an entire industry of spare batteries, charge cases, mini power cables and much more. However, the underlying problem has never been solved. Why can’t we just create a battery that lasts longer?   Well, researchers … Continue reading Developing a Longer Life Smartphone Batterys
