4. Li-ion battery
Lithium-ion batteries are developed on the basis of secondary lithium batteries. It solves the two technical problems of poor safety and short charge and discharge life of secondary lithium batteries in principle.
Its typical battery system is composed as follows: the positive and negative electrodes of the battery are composed of compounds or materials that can intercalate and extract Li+, among which, positive electrode: lithium or transition metal oxide (LiMO2); negative electrode: carbon that can intercalate Li+ (form LixC ); Electrolyte: organic solution or solid polymer.
The main characteristics of lithium-ion batteries are:
1. High density, 1.5-2 times that of Ni-MH batteries;
2. High voltage, the terminal voltage can reach 3V, which is more than twice that of Ni-MH battery (1.2V);
3. No pollution;
4. Long cycle life, more than 10 million times;
5. Large load capacity, can discharge continuously with high current;
Lithium-ion battery is a new type of battery with the best comprehensive performance among all rechargeable batteries. Compared with other batteries, lithium-ion batteries have great advantages in specific energy, specific power and cost when used in hybrid vehicles.
Many units at home and abroad have paid special attention to the research and application of lithium-ion batteries. The following lists the parameters of some companies' lithium-ion batteries.
From the perspective of the advantages of lithium-ion batteries, it is very suitable for hybrid vehicles, but the decomposition temperature of lithium-ion battery materials is about 200 ° C, it will release oxygen molecules, and the electrolyte will burn rapidly under the action of high temperature, causing spontaneous combustion and flammability of the battery. Explosion risk.
Therefore, in order to ensure the safety of lithium-ion batteries, a thermal management system must be done, including over-temperature protection (OTP), over-current protection (OCP), over-charge protection (OVP), and over-discharge protection (UVP). Although this method is effective, it will inevitably increase the cost of the battery and increase the volume and weight of the battery.
