Photos, Figure of Conventional & Polymer LIBs

Thanks to Anonymous for these advanced battery comments and links of July 23, 2020.

Photos of [solid] all polymer Lithium-ion Batteries (LIBs), co-developed by APB and Sanyo Chemical Industries (SCI), are introduced at [1] and [2].

Pete Comment: "Resin" and "Polymer" is essentially the same thing. A Resin is liquid when pored, then cures/hardens into a solid polymer. Meanwhile conventional Lithium-ion Batteries (LIBs) use an electrolyte which remains liquid.

          "(a)" ) with 40 LIB-cells being bipolar stuck-structured and directly connected.

The DoD is definitely interested in better batteries:

"NanoGraf wants to build energy dense batteries that reduce that weight while allowing
war fighters to operate longer without replacing or recharging their batteries. The
company recently announced that DoD had awarded the company a $1.65 million Small
Business Innovation Research grant to develop silicon anode-based lithion-ion portable
batteries to replace the graphite anode lithium-ion batteries currently used by the
military. The goal is to develop batteries with a 50-100 percent increase in runtime."
