Discover Battery has been around since just after WWII. I think that since each Li battery is native to the system voltage, the way to get some redundancy is to simply have more than one battery, most systems will anyway. Then if one fails you can use the other ones until the failed one is replaced or fixed. A lead battery would be less prone to catastrophic failure, alkaline batteries even more so if you can handle the cost and other issues, so there is something to be said for that. I have multiple inverters and battery banks and it has come in handy when there are failures (inverters).
