Chemical formula
Charging: 2 pbso ₄ + 2 h ₂ O = PbO ₂ + Pb + 2 h ₂ SO ₄

Discharge: PbO ₂ + Pb + 2 h ₂ SO ₄ = 2 pbso ₄ + 2 h ₂ O]]> 2018-12-06 00:41:01 UTC https://padlet.com/2018141023/kristine123/wish/311642409 Is it health or effect？ 2018141023 https://padlet.com/2018141023/kristine123/wish/311642410 Yes, it does. A button battery discarded in nature can pollute 600,000 litres of water, equivalent to a person's lifetime water consumption]]> 2018-12-06 00:41:01 UTC https://padlet.com/2018141023/kristine123/wish/311642410 What the purpose of including that ingredient in the product 2018141023 https://padlet.com/2018141023/kristine123/wish/311642411    Partition (paper) in order to prevent positive and negative plate contact, resulting in internal short circuit self-discharge
Lead pin can be used as a current path to connect the positive and negative poles of two single batteries
Battery shell (cover) made of hard rubber (plastic), used for the placement of plate groups and electrolyte

I begin to learn how does battery hurt the environment. But you need to add more information .Maybe you also need to introduce "how does it hurts the environment"
Kristine:Thank for your question
Firstly, mercury discarded in nature batteries will slowly spill out of the batteries and into the soil or water
Second, they enter the body through crops and damage the kidneys.]]> 2018-12-10 06:12:39 UTC https://padlet.com/2018141023/kristine123/wish/312783171 By Auriya 2018051013 https://padlet.com/2018141023/kristine123/wish/312843028 Your padlet makes feel very comfortable. The background picture is a very nice sky. I learn some chemical that I don't know. I also know some properties about the battery. The melting high is good for our life I think. It's also means the battery is not easy to burn .  If we didn't care about the refuse sorting, what does the battery will effect to the environment?

I didn't know before and I know that I can't Anywhere the litter after use that because the chemical composition is bad for the environment, by the way you should write something in you own opinion.
 kristine;thank for your adivice,you can find it in my padlet]]> 2018-12-10 11:14:15 UTC https://padlet.com/2018141023/kristine123/wish/312854926 Arthur 2018140004 https://padlet.com/2018141023/kristine123/wish/312865508 Dear Kristine, good job!
I really learn a lot from your padlet, I can't imagine how did you create such a good padlet.

#1Before I read your padlet, I always thing that bettery only use H2SO4, but now I know that it also use H20.

#2Through your padlet, I know that battery could pollute water, and make humans' body become bad, but could you please tell me how it makes our body become bad?

#3I think your pictures' places are very good, one square one picture, it makes me feel good.
I can learn it from you.
Kristine:thank you,The metal in waste battery has very toxic heavy metal, the destructive force to human central nervous system is very big

However, we should also reasonably deal with waste batteries when using them to reduce the impact on the earth's environment.Batteries do great harm, but the earth's current demand for batteries is great, we can only look for other environmental protection energy to replace batteries, do not pollute the environment, but also to meet People's Daily needs.
We can use windmills to use wind energy instead of batteries
