The new battery should be much lighter more powerful and not dependant on cobalt... like you said...the panasonic battery design dates back to the 1994 jelly roll.... it would be great to have a more versatile battery chemistry with the number of batteries that are going to be need with the cars and trucks... plus they could deal with the NPWZ range extender...the fuel cell that Elon laughs about...
XNRGI has developed a lithium metal battery utilizing porous silicon as the electrode substrate and by merging the battery design with the low cost and manufacturing benefits of the silicon industry. The technology is based on the most versatile manufacturing concept that battery industry has seen in its long history and has the potential to solve numerous disadvantages of the conventional battery technology. The design is “chemistry” agnostic as it doesn’t restrict use of almost any cathode material, including the most common LCO, NMC, NCA, or LFP cathode materials. The critical feature of the proposed configuration is a three-dimensional, highly repeatable structure, with a 50X larger surface area for reaction with millions of small pores. The main expected advantages of this method include: high energy density demonstrating (> 1600 Wh/L) 405 Wh/kg 6X the energy density of a traditional Lithium Ion battery. The next generation Lithium Metal Air (4400 Wh/L), 680 Wh/kg, 10X a traditional lithium ion battery. XNRGI batteries have high currents for fast charge and discharge, long cycle life, safe, and low-cost high volume batch fabrication.
