What is the chemical and mechanical structure determine s the battery's
life?
The is no chemical difference. The mechanical difference is that some
batteries have thicker plates mounted more solidly. They tend to last longer.
Exception! The Optima batteries (spiral cell) not only use a slightly
different electrolyte but have a completely different construction than
conventional batteries. They are so superior that they will replace
conventional batteries entirely. In fact, they are being sold under other
names already, Champion and Exide come to mind.

Then why don't Optimas last any longer than conventional batteries?
Unless you do a lot of off-road racing or need a completely sealed,
spill-proof battery, an Optima is a waste of money even compared to buying a
new $29.95 Wal-mart battery every two years.

Luckily Wal-mart (N)ever-start batteries have a 36 month warranty.
Usually they start breaking down after two years, so I go and have it
replaced for free. Ive done this twice already over the past four
years. If you dont have the original receipt, you can still have it
replaced by showing them the little round sticker on top, which has
the month and year it was sold.
Luckily I've got a manual so any dead-battery cold mornings I just
roll it down the hill, pop the clutch (and thus crank the crankshaft
which in turn turns the timing belt and alternator which in turn
powers up the electronics which in turn sparks the chamber), and it
starts up. One time I messed up and had to push it back up the hill
and try over again ;)

They're not bad. They're either Delco or Johnson Controls.
