A preparation method of CsDFP for aqueous negative electrode slurry includes carrying out ion exchange reactions with LiPO.sub.2F.sub.2 and a cesium source. The activation energy of Li.sup.+ intercalation in the negative electrode is reduced due to the existence of Cs.sup.+, leading to a better rate performance. Further, the impedance growth rate of the batteries is reduced and the high temperature storage performance is excellent since PO.sub.2F.sub.2— participates in the electrochemical reaction to form a stable low-impedance SEI film on the surface of the negative electrode plate. Moreover, films are continuously formed to repair the SEI films under the gradual release of CsDFP, which is conducive to inhibiting the growth of lithium dendrites during long-term high-rate cycling, thereby obtaining an improved cycle performance.

A metal boride aerogel includes a three-dimensional aerogel structure comprising metal boride particles having an average diameter of less than one micron. A method is disclosed for forming a metal boride aerogel including dispersing boron nanoparticles in a solution of a metal salt, forming a boron-loaded metal oxide precursor gel using the dispersed boron nanoparticles in the solution of the metal salt, drying the boron-loaded metal oxide precursor gel to form a boron-loaded metal oxide precursor aerogel, and heating the boron-loaded metal oxide precursor aerogel to form a metal boride aerogel. The metal boride aerogel is essentially free of metal oxide.
