A spinoff from CalTech called Sienza Energy has come up with a new silicon EV battery that does away with cobalt. The secret is a nanoscale structure that resembles a plastic badminton birdie but delivers the triple threat of cost, performance, and safety
Conventional lithium-ion batteries deploy millions of micron-sized particles in their electrodes. In contrast, the Sienza EV battery boots the scale into nano-territory with billions of structures, resulting in a surface area 100 times that of conventional batteries. In addition to more efficient heat dissipation, the expanded surface area is a key factor in the improved performance of the new batter

PSR Analysis: As a mineral, cobalt has some dark undertones with much concern being raised about the use of child labor in its mining, and since its cost is high, any move away from cobalt is appreciated. PSR
