本文提出一种最小活性物质电池模型，解析其充放电特性，发现考虑活性维持成本时，充电功率-效率权衡呈环状且效率有有限时间最大值，区别于被动设备。
AI 中文摘要
利用活性物质为功能设备供能已引起越来越多的兴趣。我们提出了一个用于存储从活性物质中提取能量的最小电池模型，并解析地推导了其充放电特性。当考虑维持活性的能量成本时，充电功率-效率权衡变为环状，且效率达到有限时间最大值，这与被动能量设备形成鲜明对比。
英文摘要
Harnessing active matter to power functional devices has attracted growing interest. We propose a minimal battery model for storing energy extracted from active matter and derive its charging and discharging characteristics analytically. When the energetic cost of sustaining activity is included, the charging power-efficiency trade-off becomes loop-like and the efficiency attains a finite-time maximum, in sharp contrast to passive energy devices.
