An composite comprising amorphous carbon nitride (ACN) and zinc oxide is derived from ZIF-8 by pyrolysis. The composite is a promising anode material for sodium-ion batteries. The nitrogen content of the ACN composite is as high as 20.4 %, and the bonding state of nitrogen is mostly pyridinic, as determined by X-ray photoelectron spectroscopy (XPS). The composite exhibits an excellent Na(+) storage performance with a reversible capacity of 430 mA h g(-1) and 146 mA h g(-1) at current densities of 83 mA g(-1) and 8.33 A g(-1) , respectively. A specific capacity of 175 mA h g(-1) was maintained after 2000 cycles at 1.67 A g(-1) , with only 0.016 % capacity degradation per cycle. Moreover, an accelerating rate calorimetry (ARC) test demonstrates the excellent thermal stability of the composite, with a low self heating rate and high onset temperature (210 °C). These results shows its promise as a candidate material for high-capacity, high-rate anodes for sodium-ion batteries.

In this paper, a hierarchical nanostructure LiFePO4@C composite was firstly fabricated by an oleylamine mediated method. The oleylamine played a multifunctional role in restricting the particle size and forming the porous nano-structure of LiFePO4@C composite. Benefiting from its hierarchical structure, LiFePO4@C exhibited superior electrochemical performance, especially at low temperature. It can deliver a capacity of 117 mA h g−1 at a current density of up to 700 mA g−1 (about 5 C) at −20 °C.

The protection layer was introduced to the surface of the Li anode to enhance the charge/discharge performance of lithium/sulfur batteries. The Pt protection layer was formed by magnetron sputtering method. When the Li anode is coated with the protection layer, the unit cells with a liquid electrolyte showed an enhanced charge/discharge performance, resulting in an average discharge capacity of 750mAh/g during 90 cycles. All the charge/discharge tests were performed at room temperatures.

The suitability of some different kinds of liquid electrolytes with a 1M solution of LiCF3SO3 was evaluated for discharging capacity and cycle performance of Li/S cells at room temperature. The liquid electrolyte component was found to have a profound influence on the discharging capacity and cycle property. The lithium–sulfur battery based on the alcohol-ether binary electrolyte shows two discernible voltage plateaus at around 2.4 and 2.1 V, which correspond to the formation of soluble polysulfides and of solid reduction products, respectively. However, the liquid electrolyte based on carbonate electrolyte shows a bad compatibility with sulfur cathode. The lithium sulfur battery can not deliver acceptable discharging capacity and cycle performances.
