Rechargeable battery features and components
First Claim
1. A battery comprising:
- a housing characterized by a first end and a second end opposite the first end, wherein the housing comprises a circumferential indentation proximate the first end, wherein the housing defines a first interior region between the first end and the circumferential indentation, and wherein the housing defines a second interior region between the circumferential indentation and the second end;
a set of electrodes located within the housing, wherein the set of electrodes is positioned within the second interior region of the housing;
a cap at least partially contained within the first interior region of the housing, wherein the cap is characterized by a first surface facing the set of electrodes; and
a first insulator positioned within the housing, wherein the first insulator extends across the circumferential indentation from the cap to the set of electrodes, wherein the first insulator is characterized by a first outer radius at a first end proximate the cap, wherein the first insulator is characterized by a second outer radius greater than the first outer radius at a second end proximate the set of electrodes, and wherein the first insulator is characterized by a chamfered edge on a radially outermost surface of the first insulator extending to the first end of the first insulator.

Abstract
Energy storage devices, battery cells, and batteries of the present technology may include a housing characterized by a first end and a second end opposite the first end. The housing may include a circumferential indentation proximate the first end. The housing may define a first interior region between the first end and the circumferential indentation, and the housing may define a second interior region between the circumferential indentation and the second end. The batteries may include a set of electrodes located within the housing. The set of electrodes may be positioned within the second interior region of the housing. The batteries may include a cap at least partially contained within the first interior region of the housing. The batteries may also include a first insulator positioned within the housing. The first insulator may extend across the circumferential indentation from the cap to the set of electrodes.
