I have the following shelf in the garage that is used to store and charge batteries for tools, garden machines, bicycles.
The shelf and back panel are currently in MDF which is associated with fire risk, so I would like to replace it with something fireproof (the wall behind is concrete). Can anyone suggest a fireproof board material that would be suitable so I can just replace the shelf and back panel? I want the items easily accessible, so metal cabinets, etc., are not an option. Ideally, it should be fairly easy to screw into so that various chargers can be attached in the future. Or alternatively, if there is some type of metal tool board with a shelf and that is easy to attach various things to?
There is paint that is fire-retardant.
Probably really expensive 😬

Don't really believe in any intumescent fireproof paint. Thermal runaway in a lithium battery can drive the temperature up to 1000 °C and even aluminum melts.
Eternit?
More realistically perhaps could be klinker and mounting adhesive for attachment.
Some type of fibercement board would be good but haven't really found anything yet that can be purchased in small quantities. Klinker could work but feels unnecessarily heavy and noisy.
The cabinet and back are now in MDF which, of course, has associated fire risk
The question is how much it affects in the event of a fire. MDF is quite fire-resistant and in practice, it probably doesn't make much difference in a fire. I would think more in terms of fire spread and perhaps smoke gases if one wants to have a slightly more advanced discussion.

Lithium batteries typically burn with long jet flames, which is why it is advantageous that they are on a stable non-combustible surface in case of spontaneous combustion. If the surface catches fire and collapses, causing the burning battery to bounce against the floor, the risk of ignition of nearby objects (such as cars, gas cylinders, fuel cans, and other things often stored in garages) increases.
If the base catches fire and collapses so that the burning battery bounces to the floor, the risk of ignition of nearby objects (such as cars, gas cylinders, fuel cans, and other items often stored in the garage) increases.
Yes, that's what I'm getting at with MDF being fire-resistant. I'm quite convinced that the batteries would have burned out long before the shelf has charred enough to collapse. I think there's a greater risk of the fire spreading by burning batteries falling off the shelf due to lack of edges than it "burning through". But of course, if the shelf catches fire and continues to burn independently, it could become a second phase in the process.
Some form of "steel tray" would probably be optimal.
Elfa tracks and wire shelves. Use Elfa baskets that hang on the tracks for the chargers.
If you want a bin, metal flower boxes. Or some metal box that you build your own brackets for.
An oven tray with holes for screws and nuts works if the Elfa tracks are installed (or moved) at the right distance. Otherwise, the sides of many washing machines work well as shelves.
Vermiculite boards of the type used for insulating stoves feel a bit bulky and fragile for this purpose, although it is an excellent fireproof material; but in terms of strength, ordinary gypsum would probably beat vermiculite.
I am still on the hunt for a suitable fiber cement board. I might possibly be able to get hold of an old Eternit board, but it doesn't seem very appealing to start working on one of those. Plan B tiles, Plan C an ELFA shelf.
I bought a shelf similar to the one below and installed it by the workbench. Completely made of metal and convenient for having screwdrivers, work lamps, etc., hanging and easily accessible. Can't quite remember where I bought it, but probably Amazon.
Check for interior fittings for service vehicles. There are plenty of tool boards, hooks, shelves, drawers, etc. All made of metal. Probably available on the second-hand market as well.
