All commercial Li-ion batteries are prone to explode if short-circuited, particularly internally. Internal short-circuit is possible due to impurity contamination during the process of battery manufacture. Most battery accidents capturing media attention are of this nature. Or, as a result of battery structural failure because of puncture or impact in an accident for example, a Li-ion battery also explodes. Basic design idea in commercial batteries for the prevention of such internal short circuit-induced thermal runaway or explosion relies on the insertion of a separator between cathode and anode electrodes inside the battery. This separator is good enough for normal conditions of battery use but not more. When subjected to severe impact or even penetration in an accident, this separator is virtually useless in withholding the drastic explosive battery energy release. The desire by the consumer for a non-exploding Li-ion battery is most obvious. To enhance the safety level a new generation cell which adopts STOBA is currently under development. STOBA, the abbreviation of self terminated oligomer of hyper-branched architecture is proved to be an effective solution to prevent cell thermal runaway from internal short.
