Abstract Li-ion batteries were first commercialized by Sony in 1991 and have been used widely in portable electronic devices, electric vehicles and grid applications. Although Li-ion batteries have achieved a phenomenon commercial success and become so pervasive and indispensable in our modern life, their development has been sluggish and fallen way behind the rapid advancement of electronic technologies. Batteries with a higher energy density than Li-ion batteries are highly desired for many emerging applications. It is widely recognized that solid metallic lithium batteries (SMLBs) are one of the most promising candidate technologies. The first research on SMLBs was reported by Michel Armand in 1978. At almost the same time, Liquan Chen studied lithium-ion conductors in Germany with Werner Weppner in 1977. When he came back to China in 1978, he initiated and pioneered the research on SMLBs and related fundamental studies of solid-state ionics in China for the first time. In this interview, Prof. Chen reviews his work of the past 40 years in solid lithium batteries and lithium-ion batteries, and the renaissance and future prospects of SMLBs.

The electrolytic solutions of contemporary Li-ion batteries are made exclusively with the organic solvents since anodic materials of these batteries have potentials with greater negativity than the potential of the water reduction, thus the organic electrolytes can withstand the voltages of 3-5 V that are characteristic for these batteries. Ever since it was discovered that some materials can electrochemically intercalate and deintercalate Li+ ions in aqueous solutions, numerous studies have been conducted with the aim of extending operational time of the aqueous Li-ion batteries. Manganese oxide has been studied as the electrode material in rechargeable lithium-ion batteries with organic electrolytes. In this paper its electrochemical behavior as an anode material in aqueous electrolyte solutions was examined. MnO2 as a component of nanodispersed MnO2/C (Vulcan?) composite was successfully synthesized hydrothermally. Electrochemical properties of this material were investigated in aqueous saturated LiNO3 solution by both cyclic voltammetry and galvanostatic charging/discharging (LiMn2O4 as cathode material) techniques. The obtained composite shows a relatively good initial discharge capacity of 96.5 mAh/g which, after 50th charging/discharging cycles, drops to the value of 57mAh/g. MnO2/C (Vulcan?) composite, in combination with LiMn2O4 as a cathode material, shows better discharge capacity compared to other anodic materials used in aqueous Li-ion batteries according to certain studies that have been conducted. Its good reversibility and cyclability, and the fact that hydrothermal method is simple and effective, makes MnO2/C(Vulcan?) composite a promising anodic material for aqueous Li-ion batteries.

One of the main goals for most of the research in advanced Li-ion batteries is to develop cathode materials with improvement on cost and toxicity. This is to replace the existing commercial cathode material, LiCoO2. LiNi0.4Co0.6O2 was introduced as one of the most promising candidates for a cathode material due to its lower cost and higher capacity compared with LiCoO2. Modification of cathode materials by substituting with other materials is one of the alternative ways to improve the electrochemical performance of the material. In this case, a little amount of Ti was substituted to replace Co in order to give the material LiNi0.4Co0.55Ti0.05O2. Results showed that the substituition of some Co with Ti improves the electrochemical behavior of the material.
