Wow, I just learned we're in the "renewable energy" era. [View all]

I came across a paper today in a journal I read regularly, Enabling Superior Electrochemical Performance of Lithium-Rich Li1.2Ni0.2Mn0.6O2 Cathode Materials by Surface Integration (Guo et al., Ind. Eng. Chem. Res. 2020, 59, 43, 19312–19321) which begins like this:

Since the dawn of the renewable energy era, lithium-ion batteries have played a crucial role in the renewable energy field.(1−4)Among all cathode materials, lithium- and manganese-rich (LMR) layered cathode oxides with the chemical formula Li2MnO3–LiMO2 (M = transitional metal) are regarded as the most promising cathodes because of their extraordinary specific capacities (>250 mA h g–1) at high potentials.(5−7) It is well known that the ultrahigh discharge specific capacities of LMR cathodes are ascribed to the joint participation of anions and cations in the redox reaction...

Wow.

I had no idea. I keep thinking that carbon dioxide concentrations are going up at a record pace, but here were are past the "dawn of the renewable energy" era that I've been hearing about my whole damned adult life, and I'm not young.

I always thought that the "renewable energy era" would mean the end of the climate change problem. I guess I'm missing something.

It's a new strategy, very popular in some circles I think: When you've lost and failed, claim you won and succeeded.

Nice cathode, though, no cobalt, which should reduce the reliance on the child slaves who dig cobalt in the Congo River region.
