Battery electronification: intracell actuation and thermal management.

ABSTRACT: Electrochemical batteries - essential to vehicle electrification and renewable energy storage - have ever-present reaction interfaces that require compromise among power, energy, lifetime, and safety. Here we report a chip-in-cell battery by integrating an ultrathin foil heater and a microswitch into the layer-by-layer architecture of a battery cell to harness intracell actuation and mutual thermal management between the heat-generating switch and heat-absorbing battery materials. The result is a two-terminal, drop-in ready battery with no bulky heat sinks or heavy wiring needed for an external high-power switch. We demonstrate rapid self-heating (∼ 60 °C min^-1), low energy consumption (0.138% °C^-1 of battery energy), and excellent durability (>
