I am on a project building a cube sat and I am concerned with mitigating the risk of battery failure during operation. For those engineers scientists out there, what are the biggest risks I need to worry about for the battery? For example, is it the extreme environmental conditions, cell design failure, degradation, or something else?

We are using a Li-ion prismatic cell. Our battery specs are as following: voltage 3 to 4.2 V, and capacity 1.8 Ah at C/5 rate at 23° C.
 
NEVER!!!! but if so, the biggest risk would be an... well for example... an area 51 Satellite falling from the sky to ether... expose alien technology to us or for it to land on the san andreas fault and trigger (THE BIG ONE) an earthquake.

P.S Satellites are made up of solar powered flares or thingies to make them power and fly off of the power of the sun (with no extension cords)
 
here? this bunch of idiots? you've got to be kidding...

please review the literature: premature battery failures are generally due to shorted or open cells due to temperature fluctuations.

to be successful in this field you need to show better judgement. please reconsider your research goals.
