Proprietary materials multiply Li-ion battery capacity
Economically practical Li-ion prototype batteries incorporate mass-produced silicon nanofibers that enable higher energy capacity.

TruSpin Nanomaterial Innovation, an advanced materials company engaged in battery technology, has announced positive third-party tests evaluating the performance of the company's prototype batteries.  These tests, conducted by SpectraPower, validate the use of TruSpin's silicon nanofibers to reliably multiply the energy capacity of Li-ion batteries.

Summarised test results are available here.

"These results provide further confirmation of our material's ability to reliably augment the energy capacity of Li-ion batteries.  The advent of this technology challenges previous time horizons for the widespread adoption of electric vehicles and clean energy sources," said Robert Agnew, CEO of TruSpin.

TruSpin uses a proprietary process to mass produce exotic compositions of nanofibers, a new type of material with useful properties. Their prototype batteries incorporate silicon nanofibers within the negative side of the battery, referred to as the "anode." For years, scientists have known that using silicon this way increases the energy capacity of batteries, but they're challenged by silicon's tendency to expand as the battery charges. Because of this, companies like Tesla use a relatively small amount of silicon in their batteries. A handful of startups focused on silicon anode technology offer other types of nanomaterials to increase the silicon content.  They have attracted massive investments, but the complexities of their production techniques render these solutions economically impractical.
