To date, there has been no report on fast-charging and Ahlevel sodium-ion batteries (SIBs) by utilizing thick hard carbon anodes that demonstrate prolonged cycling life and high areal capacity at high rates. Further, the relationship among the complex structure of hard carbon, storage mechanism, and fastcharging performance in alkali-metal ion batteries has been a subject of ongoing debate [1,2].

The trends of exponential growing core counts incur new requirements on operating systems. The contemporary monolithic OSs protect shared kernel data by locking in multicore environment. However, the lock contention of OS functions may lead to overall performance degradation. This paper adopts microkernel architecture for scalability concerns, since it has flexibilities for the management of computing resources and explicit data layout to avoid locking. We present a scalable Memory management service(MMS) based on microkernel OS. The physical memory is distributed into servers to remove the lock contention over page pools. Then we discuss the new problems, including load balance and "distributed memory fragmentation". MMS is divided into one master and multiple slaves. The master is a coordinator for adjusting loads and routing requests with a global memory view,while the slaves are responsible for the management of distributed page zones and virtual memory areas. The experimental results show that MMS achieves better scalability than Linux on a 32-core machine.
