According to foreign media reports, Prieto Battery, a 3D lithium-ion battery technology company, announced the results of Energy Assurance LLC's first third-party certification for it. Testers tested a group of Prieto fully assembled batteries with patented 3D positive electrodes according to UL and IEC lithium-ion chemical standards. As a result, all Prieto batteries achieved a 100% success rate and achieved zero failures in the test. 

The Prieto battery system is designed around a porous copper structure (copper foam), which is conformally coated by an ultra-thin polymer electrolyte and then surrounded by a positive electrode matrix. The resulting three-dimensional structure lithium-ion battery has interpenetrating electrodes, extremely short Li + diffusion distance, and power density far greater than the current two-dimensional structure. Copper antimonide (Cu2Sb) electrodeposited on the copper foam makes the positive electrode stable and exhibits ultra-large capacity over a series of cycles. This foam battery can be customized to optimize for power density or energy density. 

Prieto is committed to producing safer lithium-ion compounds to meet market demand. Currently, the company has two products under development to provide solutions to eliminate fire hazards to replace current lithium-ion compounds. The first is a newly tested 3D positive electrode, which is assembled into a full battery using a traditional liquid electrolyte; the second 3D solid-state battery uses Prieto's proprietary solid polymer electrolyte. 

Based on the recent test results, Prieto will initiate the next round of financing to mass produce 3D cathodes and accelerate the commercial prototyping of 3D solid-state batteries. The company's mission is to commercialize patented 3D lithium-ion battery technology, which uses non-toxic materials that can be customized in shape to provide conversion performance at a very competitive cost. 

In addition, Prieto has patented a unique electroplating manufacturing process that uses non-toxic materials to produce batteries at a competitive price. Prieto's laboratory and headquarters are located in Fort Collins, Colorado.
