• It's a chemical reaction - there's a gradual degradation in the anode/cathode as a reaction with the electrolyte. There's environmental factors to it too - temperature has an effect, and if you can control the temperature over time, you can reduce the effect. This lecture …

• Battery science is fascinating. Here's in an-depth look at degredation: [VIDEO] The speaker (Jeff Dahn -- he now works with Tesla) pioneered a faster way to tell how fast a battery will degrade (which means you can iterate your design faster!)
