Oh, I made a mistake. What i meant was 'not' a conductivity but 'the rate of conduction heat transfer' Sorry :( I'll edit my subject.

I edited it.

When we measure 'the rate of conduction heat transfer'=Q , we assume that the hot side and the cold side's area are same. But if the both side's area is different to each other, how can i know the rate of conduction heat transfer? like below figure. Would you like to help me?? Thanks.

Because it's a 18650, it might be about 3.7V. Also, the max current of Q1 is 50 nano A.

Well, because i can change the battery to 18650(standard), so you might not to be worry about that.

I made a Li-ion charging circuit with LTspice, and I wonder if it works well. Could you check this??

Thanks for your help! have a good day

I'd like to use LTspice, but I can't find the Li-ion battery component. Would you find me the component(or library)? Thanks.

I want to know the time for charging it.

Can secondary cell can be described in circuit simulator?? With other symbols like capacitor. Also I wonder if there's a program that provide secondary cell(like Li-ion battery). Please help me

What is the fastest circuit to charge a supercapacitor?? could you show me??

I'm in a project that make a powerbank with supercapacitor. I made it but it didn't work. Can you confirm it?? My circuit is here. The green one is a board (charging board, 864-kc v1.0). It gives 4.2V DC to capacitor.

I tried it, but it didn't work. I charged the caps and tried to charge with the board, but i couldn't charge them

Um, guys, I tried to make a batteries, but it doesn't work. I used DMM but it displayed 0V when i measured the charging part.(The charging board's 'B+' and 'B-') I think it is because of the board, so i want to find another one. The board's name is '864-KC v1.0'. Google it! and the circuit was...
