Copper foam substrate of the battery, the battery does not contain any combustible electrolytes, safer, and longer battery life than the general charge density is 5 times faster, half of the battery, but also than the average battery manufacturing cost is lower, smaller.
this is kind of 3D printing tech batteries. also belongs to future new batteries. hope lithium batteries cost future become less could find way from 3D priting tech. but any other prevailing lithium ion batteries, you can still look at SNL.
