Abstract
An example device includes a lithium-based battery having conductive battery contacts protruding from a surface of the battery, where a non-conductive portion of the surface of the battery separates the conductive battery contacts. The battery is a type that undergoes an expansion during charging in which the expansion of the lithium-based battery includes an outward bulging of the non-conductive portion of the battery surface. The device includes a substrate having conductive substrate contacts. The conductive battery contacts are electrically connected to the respective conductive substrate contact via a flexible electrically-conductive adhesive that physically separates the conductive battery contacts from the respective conductive substrate contacts and allows for relative movement therebetween caused by the expansion of the lithium-based battery.
