背景技术：Background technique:

自热饭煲、自热饭盒都是利用化学能加热熟食品、煮米饭、下饺子、煮面条，但它们只能依靠厂家调整包装剂量大小实现发热时间长短的目的，属于不可再生的一次性消耗类资源包装产品。随着数码产品如手机、笔记本电脑等产品的广泛使用，锂离子电池以优异的性能在这类产品中得到广泛应用，并在逐步向其他产品应用领域发展，如电动工具、电动车、路灯备用电源、航灯、家用小电器等，可以说拥有了最大的应用群体。据资料显示，2008年全球锂离子电池产量为27.8亿颗，产业规模71亿美元，到了2011年锂离子电池产量增长到46.4亿颗，产业规模153亿美元；在《2012年中国锂离子电池产业研究》显示，中国是世界上除日本外最大的锂离子电池生产国及主要消费国，规模达到397.4亿元；2012年4月18日，国务院讨论通过了《节能与新能源汽车产业发展规划(2012～2020年)》(下称《规划》)，明确了以纯电驱动为汽车工业转型的主要战略取向，推广普及非插电式的混合动力汽车，并提出了在2015年纯电动以及混合动力车累计产销量达到50万辆，到2020年超过500万辆的目标。可以预计，《规划》这一强大的助推剂，将有望改变当前世界锂电池产业格局。锂离子电池中的磷酸锂铁电池则同时拥有锂钴、锂镍和锂锰的主要优点，不含钴等贵重元素，原料价格低且磷、锂、铁存在于地球的资源含量丰富，不会有供料问题，而且，工作电压适中(3.2V)、电容量大(170mAh/g)、高放电功率、可快速充电且循环寿命长，是目前业界认为较符合环保、高性能要求要求的锂离子电池。电热膜作为电能的利用效率往往远远高于传统一次能源的利用效率，电热膜加热效率(85％)又高于普通电热丝加热效率(40％)。电热膜是一种超导电薄膜。它是按一定配比，把非金属半导体材料与另一种在高温条件下起粘合作用的粉状物，调合均匀，涂覆于各种加热体的底部或周围，经烧结而成。电热膜加热功率在0.1-2千瓦之内，使用寿命可达2000小时。因此，寻求设计一种使用锂电作为电源，利用高效膜加热技术的电饭煲具有较高的社会意义和经济价值。Self-heating rice cookers and self-heating lunch boxes use chemical energy to heat cooked food, cook rice, serve dumplings, and cook noodles, but they can only rely on the manufacturer to adjust the packaging dosage to achieve the purpose of heating time, which is a non-renewable one-time consumption class resource wrapper product. With the widespread use of digital products such as mobile phones and notebook computers, lithium-ion batteries have been widely used in such products with excellent performance, and are gradually developing into other product applications, such as power tools, electric vehicles, and street lamps. Power supplies, aviation lights, small household appliances, etc., can be said to have the largest application groups. According to data, in 2008, the global output of lithium-ion batteries was 2.78 billion, with an industrial scale of US$7.1 billion. By 2011, the output of lithium-ion batteries had increased to 4.64 billion, with an industrial scale of US$15.3 billion; "Research" shows that China is the world's largest producer and major consumer of lithium-ion batteries except Japan, with a scale of 39.74 billion yuan; on April 18, 2012, the State Council discussed and approved the "Energy-saving and New Energy Automobile Industry Development Plan ( 2012-2020)" (hereinafter referred to as the "Plan"), clarified that pure electric drive is the main strategic orientation of the transformation of the automobile industry, popularized non-plug-in hybrid electric vehicles, and put forward the plan for pure electric and hybrid electric vehicles in 2015. The cumulative production and sales volume of automobiles will reach 500,000 units, and the target of exceeding 5 million units will be exceeded by 2020. It can be expected that the powerful booster of the "Plan" will hopefully change the current pattern of the world's lithium battery industry. The lithium iron phosphate battery in the lithium ion battery has the main advantages of lithium cobalt, lithium nickel and lithium manganese at the same time. There are material supply problems, and the working voltage is moderate (3.2V), large capacity (170mAh/g), high discharge power, fast charging and long cycle life. It is currently considered by the industry to be more environmentally friendly and high-performance lithium batteries. ion battery. The utilization efficiency of electric heating film as electric energy is often much higher than that of traditional primary energy, and the heating efficiency of electric heating film (85%) is higher than that of ordinary electric heating wire (40%). Electrothermal film is a kind of superconducting film. It is made by blending non-metallic semiconductor material and another powder that acts as a bond under high temperature conditions evenly according to a certain ratio, coating on the bottom or around various heating bodies, and sintering. The heating power of the electric heating film is within 0.1-2 kilowatts, and the service life can reach 2000 hours. Therefore, it is of high social significance and economic value to seek to design a kind of electric cooker that uses lithium battery as power supply and utilizes high-efficiency film heating technology.
