In both cases, the fires and ensuing explosion were attributed to the lithium-ion battery. Amazon has discontinued the sale of such devices. So what is happening? I will leave […]
Before I start this post, I encourage all new readers to go back to the early posts if they desire to learn more about the basics of lithium-ion batteries and their operation.

The promise of even greater markets in stationary energy storage and electric vehicles is attracting interest and investment. Goldman Sachs estimates that the energy storage market could reach a demand greater […]
