锂离子电池:

锂离子电池一般是使用锂合金金属氧化物为正极材料、石墨为负极材料、使用非水电解质的电池。

充电正极上发生的反应为

LiCoO2==Li(1-x)CoO2+XLi++Xe-(电子)

充电负极上发生的反应为

6C+XLi++Xe- = LixC6

充电电池总反应:LiCoO2+6C = Li(1-x)CoO2+LixC6

正极

正极材料:可选的正极材料很多,主流产品多采用锂铁磷酸盐。不同的正极材料对照:



正极反应:放电时锂离子嵌入,充电时锂离子脱嵌。
充电时:LiFePO4 → Li1-xFePO4 + xLi+ + xe-放电时:Li1-xFePO4 + xLi+ + xe- → LiFePO4

负极

负极材料:多采用石墨。新的研究发现钛酸盐可能是更好的材料。负极反应:放电时锂离子脱嵌,充电时锂离子嵌入。 充电时:xLi+ + xe- + 6C → LixC6放电时:LixC6 → xLi+ + xe- + 6C

应用范围:

1 储能设备 :基于太阳能风能地热海洋能发电系统之储能设备 ;电网调峰;不断电系统UPS ;配合太阳能电池使用作为储能设备(比亚迪已经在生产此类电池)家庭照明等;

5 其它小型电器 矿灯
6)启动电源: 汽车、摩托车拖拉机柴油机,,铁路内燃机车电力机车、客车起动电源;
7)固定型电源:主要用于通讯、移动基站、电信、铁路运输、电力、、金融、发电厂计算机系统作为保护、自动控备用电源
8)军事领域:军队现场电子指挥系统、海(潜艇、水下机器人)、陆(军士兵系统、机器战士)、天(无人飞机)、空(卫星、飞船)诸兵种。
锂离子电池
技术已不是一个单纯一项产业技术,它攸关信息产业的发展,更是新能源产业发展的基础技术之一,并成为现代和未来军事装备不可缺少的重要粮食之一。相信在不就的将来磷酸铁锂电池将取代铅酸电池一统动力电池天下局面,且用途将更加广泛!

Comparision between LiFePO4 battery and Lead-Acid battery:

BatteryIngredients

LiFePO4 battery

Lead-Acid

Safety & Environmental Concern

Safest; no explosion; no smoke; no fire under very bad working condition; most environmentally friendly; non-toxic; no rare metal, fire resistant, easily disposed of.

Safty is acceptable; heavy pollution to water and soil; breaking ecological balance; threatening people's health especially for Children; hard to dispose of; high re-use cost.

Life Cycle

Best, up to 2000 times under 80% DOD

Very short life cycle, about 150 times under 100% DOD; maintenance needed ofen.

Long term Cost

Most economical

Cost of whole lifetime is higher than LiFePO4.

Thermal Performance

Excellent - can work normally under -20~70

The capacity decays quickly if the temperature is higher than 50.
