Description
Technical field
The utility model relates to a kind of lithium rechargeable batteries, relates in particular to adopt the transformation technology to realize 3 volts of lithium rechargeable batteries of voltage matches.
Background technology
The embedding of lithium rechargeable batteries by its lithium ion on anodal and negative pole, take off the redox reaction that embedding causes and produce electric energy, lithium rechargeable batteries use can be reversible lithium ion embed, the material that takes off embedding is as positive pole and negative material, and organic electrolyte or polyelectrolyte are injected gap between positive pole and the negative pole so that lithium rechargeable batteries to be provided.Therefore the lithium rechargeable batteries per unit mass has high relatively energy density, therefore, carries out apace and increases for the research and development of chargeable lithium ion battery.
Alkaline cell and lithium battery that present known 1.5 volts of batteries are non-chargings, and rechargeable battery is 1.2 volts of ni-mhs and nickel-cadmium cell, or 3.7 volts of lithium rechargeable batteries.Common alkaline battery capacity is little, and can only use once, and the integrated cost height not only bad for people's use, and causes environmental pollution, and ni-mh and nickel-cadmium chargeable battery output voltage are low, and two just 2.4 volts in parallel, and inefficiency.Though the output voltage of conventional lithium battery is 3.7 volts, mostly the voltage of the camera battery that daily people use is 3 volts, and power supply is improper.Therefore, substitute 1.5 volts of greatest problem that battery is non-rechargeable battery with 1.2 volts of rechargeable batteries, promptly voltage does not match.At this problem, the someone adopts the transformation technology to realize voltage matches, but the drawback of this technology is the circuit complexity, and volume is big, cost height, poor reliability.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of very simple, effective VMT voltage mate technlolgy to realize providing the lithium rechargeable batteries of 3 volts of voltages.
The technical scheme that its technical problem that solves the utility model adopts is: utilizing diode one-way only operation principle and Schottky diode forward voltage drop is that 0.3V is that 0.7V is different with the pressure drop of PN junction diode forward, a parallel Schottky diode and PN junction diode of oppositely connecting before rechargeable battery.When charging, Schottky diode forward conduction and PN junction diode are not worked because of reverse connection.But the 4.2V of charger output is through this Schottky diode step-down 0.3V, for battery provides 3.9V maximum charging voltage.When discharge, conventional lithium rechargeable batteries links to each other with load appliance with a PN junction diode by a Schottky diode, PN junction diode forward conducting and Schottky diode is not worked because of reverse connection.But battery the 3.9V of high output through this PN junction diode step-down 0.7V, for load appliance provides 3.2V the highest discharge voltage, and but the 3.0V of the minimum output of battery provides the minimum discharge voltage of 2.3V through this PN junction diode step-down 0.7V for load appliance.
The operating voltage of this 3V lithium rechargeable batteries in the 3.2V scope, can be used to substitute two joint 1.5V batteries at 2.3V.This employing that discharges and recharges diode can also discharge and recharge overload protection is provided.When charging and discharging currents surpasses maximum rating, can burn out this and discharge and recharge diode and play the destructive protection of afterbody.
The invention has the beneficial effects as follows: circuit structure is simple, and volume is little, and cost is low, the reliability height.The utility model technology is applicable to two joint logotype 1.5V batteries of any kind.
