Initial Charge

A new synthetic route to ~4 nm grain-sized SnO 2 was proposed which involved a homogeneous precipitation in a deep eutectic solvent (DES) at room temperature. The white SnO 2 precipitate was obtained from SnCl 2 ⋅ 2 H 2 O dissolved DES by injecting slow drop-wise H 4 N 2 ⋅ H 2 O under stirring. The as-prepared nanocrystalline SnO 2 has a Brunauer–Emmett–Teller surface area of 65.12m2/g with an average Barretl–Joyner–Halenda pore diameter of 3.5 nm. As anode for lithium ion batteries, the nanocrystalline SnO 2 electrode delivered an initial charge capacity as high as 1045 mAh/g and its capacity retention is 58% after 30 cycles.

Charge Temperature

Pre-charge as a key step in the battery manufacture processes, which has a great impact on the film-forming properties and electrochemical performances, especially the Li-rich system batteries. As a key influence factor, it is necessary to clarify the effect of pre-charge temperature on battery performance. In this paper, we mainly studied the influence of different pre-charge temperatures (25°C, 40°C, 60°C) on the gas production and electrochemical performance of the batteries. The results show that the increase of the pre-charge temperature will result in the increase of gas production, and the gas components are mainly CO2, H2. After the long-term cycle, the sample under 40°C maintains the highest capacity retention rate, and as the pre-charge temperature increases, the median voltage of the battery can be effectively increased. In addition, compared with room temperature pre-charge, high pre-charge temperature samples have more excellent rate performance.
