A safer rechargeable battery is offered. More concretely, The secondary battery composed to prevent the overcharge is offered.
The electrolyte salt concentration of an electrolyte solution (solid or liquid) and those absolute quantity is controlled in the rechargeable battery in this execution form by using the anode material including n-dope domain and p-dope domain and in which many electron reactions are possible. In the anode of this rechargeable battery disconnection of lithium ion will take place first with the low potential (potential of n dope) at the time of charge, next, absorption of an anion will take place with as high potential (potential of p dope) as the point. Although the career of the ion current is only a lithium ion in the potential of n dope, in p dope potential, anion current flows through the anode side and lithium ion current flows through the cathode side. Thereby, before overcharge, the electrolytic concentration decreases, the internal resistance goes up, and the overcharge is avoided.
提供了一种更安全的可充电电池。更具体地说,提供了由防止过充的次级电池组成的电池。在这种执行形式中,通过使用包括n掺杂区域和p掺杂区域的阳极材料,并且其中许多电子反应是可能的,来控制可充电电池中电解质溶液(固体或液体)的电解质盐浓度和绝对量。在这种可充电电池的阳极中,在充电时首先会发生
锂离子的分离,其电位较低(n掺杂电位),接下来,吸收阴离子时电位会升高到较高(p掺杂电位)的点。虽然在n掺杂电位的离子电流只有
锂离子,但在p掺杂电位时,阴离子电流通过阳极侧流动,
锂离子电流通过阴极侧流动。因此,在过充之前,电解质浓度降低,内部电阻上升,从而避免了过充。
