How To Solve the "AND" Problem

For batteries to be useful for a particular application, e.g. electric vehicles, portable electronics, grid storage, it must pass the unforgiving "AND test". The "AND test" requires that batteries satisfy all of the requirements simultaneously in the exact same cell design. The choice of the term "AND test" is intentional akin to Boolean logic, the outcome is positive only if all the constraints are met. The requirements for the "AND test" for a particular application are set by the consumer preferences for that product. Thus, the main challenge to solving this problem is to map the consumer preferences for a product to a set of design constraints on the battery, which can then be tested in the relevant test conditions.

In this 2022 Batteries GRC, we look forward to hosting a range of researchers that both identify the constraints for the "AND test" and ways to solve the "AND test".
