   Most research on the electrochemical dynamics in materials for high‐energy Li‐ion batteries has focused on the global behavior of the electrode. This approach is susceptible to misleading analyses resulting from idiosyncratic kinetic conditions, such as surface impurities inducing an apparent two‐phase transformation within LiNi_0.8Co_0.15Al_0.05O₂. Here, nano‐focused X‐ray probes are used to measure delithiation operando at the scale of secondary particle agglomerates in layered cathode materials during charge. After an initial latent phase, individual secondary particles undergo rapid, stochastic, and largely uniform delithiation, which is in contrast with the gradual increase in cell potential. This behavior reproduces across several layered oxides. Operando X‐ray microdiffraction (‐XRD) leverages the relationship between Li content and lattice parameter to further reveal that rate acceleration occurs between Li‐site fraction (x_Li) ≈0.9 and ≈0.5 for LiNi_0.8Co_0.15Al_0.05O₂. Physics‐based modeling shows that, to reproduce the experimental results, the exchange current density (i₀) must depend onx_Li, and thati₀should increase rapidly over three orders of magnitude at the transition point. The specifics and implications of this jump ini₀are crucial to understanding the charge‐storage reaction of Li‐ion battery cathodes.

5. LCI1, a Chlamydomonas reinhardtii plasma membrane protein, functions in active CO 2 uptake under low CO 2

   https://doi.org/10.1111/tpj.14761  

   Kono, Alfredo ; Spalding, Martin H. ( April 2020 , The Plant Journal)

   In response to high CO₂environmental variability, green algae, such asChlamydomonas reinhardtii, have evolved multiple physiological states dictated by external CO₂concentration. Genetic and physiological studies demonstrated that at least three CO₂physiological states, a high CO₂(0.5–5% CO₂), a low CO₂(0.03–0.4% CO₂) and a very low CO₂(< 0.02% CO₂) state, exist inChlamydomonas. To acclimate in the low and very low CO₂states,Chlamydomonasinduces a sophisticated strategy known as a CO₂‐concentrating mechanism (CCM) that enables proliferation and survival in these unfavorable CO₂environments. Active uptake of C_ifrom the environment is a fundamental aspect in theChlamydomonasCCM, and consists of CO₂and HCO₃^–uptake systems that play distinct roles in low and very low CO₂acclimation states. LCI1, a putative plasma membrane C_itransporter, has been linked through conditional overexpression to active C_iuptake. However, both the role of LCI1 in various CO₂acclimation states and the species of C_i, HCO₃^–or CO₂, that LCI1 transports remain obscure. Here we report the impact of anLCI1loss‐of‐function mutant on growth and photosynthesis in different genetic backgrounds at multiple pH values. These studies show that LCI1 appears to be associated with active CO₂uptake in low CO₂, especially above air‐level CO₂, and that any LCI1 role in very low CO₂is minimal.
