Provided are electrodes for lithium-ion batteries comprising: a first lithium metal phosphate material comprising a first plurality of active material particles; and a second lithium metal phosphate material comprising a second plurality of active material particles, wherein both the first lithium metal phosphate material and the second lithium metal phosphate material are LiMPO, wherein M is one or more of iron (Fe) or manganese (Mn), and wherein the first lithium metal phosphate material is blended with the second lithium metal phosphate material at a weight ratio of greater than 1:1.

Electrodes comprising blended active materials

Provided herein is an apparatus. The apparatus can include a battery cell. The battery cell can include an electrode. The apparatus can include a first solid electrolyte interphase on the electrode. The first solid electrolyte interphase can be formed from a first electrolyte having a salt concentration greater than or equal to 1 M. The apparatus can include a second solid electrolyte interphase on the electrode. The second solid electrolyte interphase can be formed from a second electrolyte different from the first electrolyte.
