A positive electrode material, a positive electrode sheet and a lithium ion battery. The positive electrode material is obtained by mixing a lithium manganese iron phosphate material and a ternary material. During mixing, a mass ratio n of the ternary material to the lithium manganese iron phosphate material in the positive electrode material is determined according to a range of a ratio k of an actual specific capacity of the ternary material to an actual specific capacity of the lithium manganese iron phosphate material. Specifically, when k is less than or equal to 1.34, n is 1 to 9; and when k is greater than 1.34, n is 0.1 to 1, so as to avoid the following situations: due to an improper mixing ratio of the two materials, a lithium ion battery prepared using the positive electrode material is prone to problems such as low capacity retention, low cycle retention, and severe gas generation during cycling. The lithium ion battery prepared from the positive electrode material may have high energy density, high capacity retention rate, good cycle performance and good safety performance at the same time.

The present application provides a vehicle bus fault recording method and apparatus, a device, and a storage medium. The method includes: sending wake-up record messages to a primary domain control node of an ECU according to a preset cycle after the ECU is woken up; receiving, by the primary domain control node, the wake-up record messages sent by at least one ECU controlled by the primary domain control node when it is detected that vehicle sleep fault detection conditions are met; and storing the wake-up record messages of the at least one ECU in a memory of the vehicle. When abnormal battery drain occurs in the vehicle, troubleshooting personnel can search for specific wake-up reasons of the vehicle by the wake-up record messages, thereby improving the efficiency of solving the vehicle battery drain problem.

A method for operating a vehicle, where one or more key devices are associated with the vehicle. The one or more associated key devices are adapted for allowing a user of the vehicle to initiate a vehicle starting operation. The method comprises the steps: initiating a vehicle shut-off sequence after initiation of the vehicle starting operation, where the vehicle shut-off sequence is initiated upon receipt of a shut-off request, where the vehicle shut-off sequence comprises a searching operation for detecting associated key devices within a boundary of the vehicle; and controlling the vehicle to entering a conditional operation mode when detecting that no associated key devices are within the boundary, wherein the conditional operation mode is authorizing a pre-determined vehicle activity preventing a non-operational state of the vehicle.
