Warfighters need batteries capable of operating power hungry devices for longer missions while reducing the weight they must carry. USSOCOMs 16Ah / 500 Wh/kg goal in a PRC-148 sized pack is ambitious approximately double the existing options on the market. Thankfully, there are several cell technologies that exist at the lab/prototype level, and a handful that will be mature enough in the short term to supply USSOCOM with this capability. The TRL alone of these cell technologies is not enough - there needs to be the production capability and industry interest to ensure these cells can be manufactured at scale. TAFs feasibility will assess the art of the possible, and document in detail all options that may meet or exceed the minimum performance, including TRL and PRL estimates, and result in a final recommendation on what TAF will build in the Phase II.
