100-year EV battery life

Battery expert Jeff Dahn, together with Tesla, designed an electric vehicle battery that could last a hundred years.

After increasing the life cycles of batteries, Dahn worked on improving their durability and energy density.  Higher energy density allows electric vehicles to travel farther before charging again.  To achieve this goal, the team used nickel in its battery mix.  The batteries are also more durable than lithium-ion types when charged at various temperatures.  In a hypothetical situation where the battery is used at a temperature of 25 degrees at all times, the battery life could exceed 100 years.

Currently, gasoline packs a high energy density compared with electric vehicle batteries.  However, the impact of fossil fuels on the climate to power engines is too much to ignore, making this new battery technology truly relevant.
