Particular embodiments may provide a lithium-ion battery comprising a MAX compound to prevent and/or decrease Manganese dissolution. In some embodiments, the MAX compound comprises the formula MAX, wherein M is an early transition metal atom, n is an integer from 1 to 3, A is a group 13 or group 14 element, and X is C or N.

MAX carbide additive materials for lithium-ion batteries

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 a cathode. The cathode can include a cathode active material. The cathode can include a coating disposed on the cathode active material. The coating can include LiMMAF(OH), where Mis a first metal, Mis a second metal, A is an anionic species, 1≤x≤2, 0≤y≤1, 0≤z≤1, and 0≤u≤1.

Electrode coatings and components thereof

A rechargeable metal halide battery fabricated with a liquid nitrogen treated metallic anode demonstrates a stable cycle life with a slow rate of degradation and high discharge capacity in comparison to battery cells with untreated anodes. The anode, which may be an alkali metal and/or an alkaline earth metal, is pretreated with the liquid nitrogen prior to formation in a battery stack. The liquid nitrogen treatment forms a metal nitride on a surface of the anode that (i) increases the surface area of the anode, (ii) acts as a passivation layer that prevents detrimental SEI-forming side reactions that degrade anodes, and (iii) suppresses dendrite growth. Where the anode is lithium, the metal nitride is lithium nitride (LiN).
