Disclosed is a rechargeable secondary lithium ion battery, having an improved anode material, cathode material and electrolyte solution, so as to reduce the formation of dendrites by deposits of lithium metal on the surface of carbonaceous material when lithium ions are inserted into the carbonaceous material during charging, and mitigate the risk of side reactions. Also disclosed are a lithium battery assembly capable of providing a high discharge pulse within a wide temperature range, and a forming method. The lithium battery assembly comprises a primary lithium/oxyhalide battery and a rechargeable secondary lithium ion battery connected in parallel to the primary lithium/oxyhalide battery, the open circuit voltage of the rechargeable secondary lithium ion battery in a full state being higher than that of the primary lithium/oxyhalide battery connected in parallel. Since the open circuit voltage of the rechargeable secondary lithium ion battery in the full state is higher than that of the primary lithium/oxyhalide battery connected in parallel, the rechargeable secondary lithium ion battery is lower than the full state when the two batteries are connected in parallel and under a load end open circuit condition, thereby alleviating ageing and self-discharging caused by side reactions. |
