Megan Geuss — Elon Musk on batteries for Australia: “Installed in 100 days or it is free”

“$250/kWh at the pack level for 100MWh+ systems. Tesla is moving to fixed and open pricing and terms for all products,” Musk tweeted. The rate would bring the price of a 100MWh system to $25 million, excluding costs like labor and shipping.

Then there was this - Lithium-ion battery inventor introduces new technology for fast-charging, noncombustible batteries

Goodenough's latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga, is a low-cost all-solid-state battery that is noncombustible and has a long cycle life (battery life) with a high volumetric energy density and fast rates of charge and discharge. The engineers describe their new technology in a recent paper published in the journal Energy & Environmental Science.

"Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today's batteries," Goodenough said.

The researchers demonstrated that their new battery cells have at least three times as much energy density as today's lithium-ion batteries. A battery cell's energy density gives an electric vehicle its driving range, so a higher energy density means that a car can drive more miles between charges. The UT Austin battery formulation also allows for a greater number of charging and discharging cycles, which equates to longer-lasting batteries, as well as a faster rate of recharge (minutes rather than hours).

Increasing capacity and longevity while decreasing toxicity should be the goal. Tesla just spent billions making a gigafactory to churn out toxic unsafe batteries for decades to come. Expect FUD over new, better chemistry.
