Battery control systems

This invention describes a battery system designed to manage the physical swelling that occurs when certain types of batteries, particularly those using lithium metal, are charged and discharged. It achieves this by incorporating special compressible areas within the battery's structure. The specific version detailed includes a boost pack and a primary energy pack, where the primary pack uses lithium metal negative electrodes and solid-state electrolytes, and the compressible parts are engineered to absorb at least 10% of the battery's expansion, often contained within a standard battery can.

Why it matters: Since 2021, research into solid-state and lithium metal batteries has intensified, making their volumetric expansion a more pressing engineering challenge. This design offers a solution to a problem that is becoming increasingly relevant as these advanced battery chemistries approach commercial viability.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedLithium metal, solid-state electrolyte, custom battery stack
