Battery's in electric cars?
Discussion
They do degrade over time. So does every part of every car, patrol, diesel, electric or powered by pixiedust.
The greatest body of experience in terms of both number of years and number of units in service is with the Mark II Prius. That came out in 2003 and the service record on those shows that most batteries on those are still basically ok after 10 years. The warrantied life is between 8 and 10 years depending on territory, and they are expected to do around 150,000 miles.
In other words it's not really a problem, and if you want to run one for 20 or 30 years you will be doing some replacements, just as you will be having engines and transmissions rebuilt.
Here's some info on the Prius battery including replacement costs. US info, as that's where most of them are, but it gives the general idea.

The Prius battery has a very easy life though - it is held between (approx.) 60-80% charge almost all of the time. Depending on use an electric car battery will see deeper discharge and charging to full capacity more often. Much depends on how well the battery maintenance system operates.The Mark II Prius came out in 2003 and the service record on those shows that most batteries on those are still basically ok after 10 years.

As an example the Tesla S 'normal' charge doesn't fill the pack completely - you have to set a specific 'range charge' for that which will be a bit less kind on the battery.
