一种新型锌锂电池的制备方法
技术领域
本发明属于锂离子电池技术领域，尤其涉及一种新型的锌锂电池的制备方法。
背景技术
随着经济的不断发展，必然引起石油资源的枯竭和环境污染、温室效应的加剧，人们必须把握经济增长，环境保护和能源供给的三者平衡关系。时代的需求召唤着高效清洁能源的开发。
伴随高新技术的发展和人民生活水平的提高，锂离子电池制造技术的进步和电池成本的下降，锂离子电池将成为化学电源的主流，其应用前景非常广阔。
从整个正负极电池材料的发展来看，目前制约锂离子电池能量密度提升的关键因素是正极材料。正极材料在锂离子电池产品组成中占据着最重要的地位，它的性能和价格直接影响到锂离子电池的性能和价格。正极材料还需要额外负担负极材料的不可逆容量损失。因此，正极材料的研究与改进一直是锂离子电池材料研究的关键。
