Abstract: The present disclosure provides a lithium-ion battery, the lithium-ion battery comprises a positive electrode plate, a negative electrode plate, a separator and an electrolyte, the positive active material comprises a layered lithium-containing compound, the negative active material comprises graphite, the positive film and the negative film satisfy a relationship 0.3?(OIc×PDc)/(OIa×PDa)?20.0. The present disclosure can make the lithium-ion battery have smaller swelling and higher charging capability, and also make the lithium-ion battery have excellent cycle life and excellent safety performance during the long-term fast charging process.

Abstract: Hierarchical multi-agent reinforcement learning may be used for joint order dispatching and fleet management for ride-sharing platforms. Information may be obtained. The information may include a status of a ride-sharing platform and a set of messages. The obtained information may be input into a trained hierarchical reinforcement learning (HRL) model. The trained HRL model may include at least one manager module corresponding to a region, and the at least one manager module may include a set of worker modules each corresponding to a division the region. At least one goal of the division in the region may be obtained based on the status of the ride-sharing platform and the set of messages. A vehicle action may be generated for each vehicle in the division in the region based on the status of the ride-sharing platform, the set of messages, and the at least one goal.
