Embodiment Construction

[0025] The present disclosure relates to rechargeable batteries having two or more internal resistance sites. The term battery as used herein is used to denote any rechargeable electrochemical energy storage device comprising one or more electrochemical cells. The battery configurations of the present disclosure can be applied to a variety of batteries such as, but not limited to, lithium ion batteries, lithium polymer batteries, nickel metal hydride batteries, nickel manganese cobalt batteries, lithium sulfur batteries, and lithium air batteries. Such batteries can be used in transportation, aerospace, military and stationary energy storage applications. An advantage of the rechargeable battery of the present disclosure is that the internal resistance of the battery can be changed in a progressive manner according to the temperature of the battery.

[0026] For example, during normal operating conditions, such as during normal or optimal operating temperatures, the internal ...

Abstract

A rechargeable battery that features two or more levels of internal resistance according to various temperature ranges is disclosed.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of U.S. Application Serial No. 14 / 189,517, filed February 25, 2014, which claims the benefit of U.S. Provisional Application No. 61 / 824,211, filed May 16, 2013, which is hereby incorporated The entire disclosures of both are incorporated herein by reference. technical field [0003] The present invention relates generally to rechargeable batteries, and more particularly, to rechargeable batteries configured with more than one internal resistance level. Such batteries include lithium-ion batteries with more than one internal resistance site. Background technique [0004] Rechargeable batteries used in electronics, transportation and grid energy storage are often plagued by low performance and safety at extreme temperatures. At low temperatures, especially sub-freezing temperatures, rechargeable batteries, especially lithium-ion batteries, exhibit extremely low power performan...
