How might microscopic humanoids contain electricity?

In my world, there are a race of microscopic humanoid organisms (0.3 mm - 0.33 mm). They live in a variety of biomes, such as leaf litter, stone and on plants and trees. In terms of technological advancement, they are near the bronze age and merely need to find/discover metal. They have domesticated pseudoscorpions, aphids, spider mites and white flies. Being in number 860,000 strong, they can mass produce "spider" silk, and have spears (for poking, not throwing), stone "swords". They have silk armor, chariots (sleds) pulled by pseudoscorpions and they can produce vinegar, formaldehyde, atropine and nicotine, although not in extremely great quantities. Most importantly, they can produce and conduct static electricity. My questions are:

1. How might such a civilization (lacking metal) store electricity for later use?
2. Can an electric motor exist on such a scale without metal?
