Relax, Lithium is what we know about. Liquid metal batteries are showing promise. They have only been researched recently. Perovskites for semiconductor solar cells also look promising Energy Fusion is expected to take off in a few years. Betavoltaic fuel cells that use nuclear waste, if batch-processed could become viable. Hydrogen fuel cells for solar flight. Plasma propulsion for Mars. I think we will be fine.
