Traditionally, lithium-ion battery cathodes face a trade-off between the energy density afforded by high-voltage anion reduction−oxidation and long-term stability. Now, incorporating polyanion motifs into a disordered oxide crystal structure is shown to stabilize the oxygen sublattice, improving capacity retention at high energy densities.

聚阴离子稳定阴离子氧化还原


传统上，锂离子电池阴极面临着高压阴离子还原-氧化提供的能量密度和长期稳定性之间的权衡。现在，将聚阴离子基序掺入无序氧化物晶体结构中已被证明可以稳定氧亚晶格，提高高能量密度下的容量保持。
