<p><span lang="EN-US">A hybrid composite containing 65 mass % of tin hexacyanoferrate mixed with 35 mass % of carbon nanotubes has been synthesized and its electrochemical behavior as a negative electrode in alkali metal-ion batteries has been studied in 1 mol L<sup>-1</sup> aqueous solution of sodium sulfate. The specific capacity of pure tin hexacyanoferrate is 58 mAh g<sup>-1</sup>, whereas the specific capacity normalized per total electrode mass of the composite studied reaches 34 mAh g<sup>-1</sup>. The estimated maximal specific power of an aqueous alkali-metal ion battery with a tin hexacyanoferrate electrode is ca. 3.6 kW kg<sup>-1</sup> being comparable to characteristics of industrial electric double-layer capacitors. The maximal specific energy accumulated by this battery may reach 25.6 Wh kg<sup>-1</sup> at least three times exceeding the specific energy for supercapacitors.</span></p>

Lithium/fluorinated carbon (Li/CFx) batteries are the highest-energy-density primary batteries which are widely used in various field. Herein, the novel fluorinated carbon (CFx) with superior performance are made of fluorination of ketjen-black. The fluorinated ketjen-black (F-KB) as the cathode material of Li/CFx delivered a high specific capacity over 880 mAh g-1 with a discharge plateau ~3.1 V (vs. Li+/Li). The energy density over 2400 Wh kg-1 for F-KB is higher than the theoretical energy density (2180 Wh kg-1) of fluorinated graphite. F-KB can be discharged at high rate of 5C delivering a high-power density of 9710 W kg-1 with the energy density of 1610 Wh kg-1, showing good performance of rate capability.
