Lithium battery puncture tests have provided many time-wasting moments on YouTube, presenting pyrotechnic displays in many versions.  Most are explosive and fiery examples of what is referred to euphemistically as “rapid deconstruction.” What if a battery could take a bullet and still offer superior energy, power and reliability?  Kokam answered this question for the military, showing that its new NANO battery technology “do[es] not experience thermal runaway when… shot,” according to a June 13 announcement. Intended “for the defense industry for use in submarines, support vehicles, armed fighting vehicles, and unmanned systems,” the battery combines three lithium-ion chemistries – Lithium Iron Phosphate (LFP), Lithium Titanate Oxide (LTO) and Nickel Manganese Cobalt (NMC) – into a single battery, Battery University explains the pros and cons of each chemistry: LFP: Li-phosphate has excellent safety and long life span but moderate specific energy and elevated self-discharge. LTO: Li-titanate excels in safety, low-temperature performance and life span. Efforts are being made to improve the …
