Battery Chemistry - Looking for resource recommendations

[Vios]

Hello all,

To make a long story short, my dad invented a different type of battery that on paper is superior to today's best lithium ion batteries. On paper. However my dad is retired, and is more interested in camping with my mom, practicing/playing music, and working on the house then pursuing a entrepreneurial project (I can't say I blame him). I on the other hand, am young (27) and want to see if it's possible to take his battery, and find some funding to develop a proof of principle, and see where it takes me.

The first step of this process is to learn a lot more about batteries and especially a lot more about battery chemistry. I'm an electrical engineer by trade, so I was hoping you all could recommend some great resources to gain a deep understanding of batteries and their chemistry. What should I be looking at? What books should I be buying?

Thanks for your help!
