LiFeP04 (Lithium iron phosphate) batteries weight a fraction of conventional lead acid batteries... Much smaller for similar output as well.
Often used in moto's and race cars, but also usable for street cars.
Some great advantages but a few key disadvantages as well...
+ Very light
+ Very small
+ Very low self-discharge rate
+ Very safe (unlike some other lithium battery technologies)
+ No gas discharge, no liquid to spill
+ Faster cranking
- Much more expensive
- Difficult to find in CCA capacity suitable for daily driver street cars (readily available in moto sizes)
- Significant drop off of performance in cold weather
- Can be damaged with the wrong type of charger
The cold weather drop off can be compensated for by going with an even larger/more expensive battery, but at some point it just doesn't make sense for a street car, especially one used as a daily driver in colder climate. I run them in my dirt bikes and big dual sport bikes... A great way to drop weight and have a superb performing battery, but if I go to the garage in the dead of winter and try to crank the 950 in cold ambient temperature with cold, thick oil, it turns over quite slowly. They do 'self warm', meaning that if you run current through them for a few minutes before trying to crank, say by turning on the headlights, they will perform better, but your still going to need a bigger battery to turn over the cold, thick oil.

However anything from PMNA is far from "bang for the buck".
This example will set you back close to $3k.

I have had the odessy street with the rinntec installation kit for 3 yrs and going strong. I do use a battery maintainer most of the time. Very light, I have aftermarket stereo with nav and bluetooth.
