There aren’t many batteries that can get an audience with the leader of the free world, but this wasn’t your everyday power pouch. Belcher had used viruses to assemble a lithium-ion battery’s positive and negative electrodes, an engineering breakthrough that promised to reduce the toxicity of the battery manufacturing process and boost their performance. Obama was preparing to…
